Prostatitis, or inflammation of the prostate, is more common than you might think — it accounts for roughly two million doctor visits every year. The troubling symptoms include burning or painful urination, an urgent need to go (especially at night), painful ejaculations, and also pain in the lower back and perineum (the space between the scrotum and anus).

Prostatitis overview

There are four general categories of prostatitis:

Acute bacterial prostatitis comes on suddenly and is often caused by infections with bacteria such as Escherichia coli that normally live in the colon. Men can suffer muscle aches, fever, and blood in semen or urine, as well as urogenital symptoms. Acute inflammation can cause the prostate to swell and block urinary outflow from the bladder. A complete blockage is a medical emergency that requires immediate treatment. Depending on symptom severity, hospitalization may be necessary.

Chronic bacterial prostatitis results from milder infections that sometimes linger for months. It occurs more often in older men and the symptoms typically wax and wane in severity, sometimes becoming barely noticeable.

Chronic nonbacterial prostatitis, also called chronic pelvic pain syndrome (CPPS), is the most common type. CPPS can be triggered by stress, urinary tract infections, or physical trauma causing inflammation or nerve damage in the genitourinary area. In some men, the cause is never identified. CPPS can affect the entire pelvic floor, meaning all the muscles, nerves, and tissues that support organs involved in bowel, bladder, and sexual functioning.

Asymptomatic inflammatory prostatitis is diagnosed when doctors detect white blood cells in prostate tissues or secretions in men being evaluated for other conditions. It generally requires no treatment.

Both acute and chronic bacterial prostatitis can cause blood levels of prostate-specific antigen (PSA) to spike. This can be alarming, since high PSA is also indicative of prostate cancer. But if a man has prostatitis, then that condition — and not prostate cancer — may very well be the reason for the rise in PSA.

Prostatitis treatments

Fortunately, research advances are leading to some encouraging developments for men suffering from this condition.

Antibiotics called fluoroquinolones are effective treatments for acute and chronic bacterial prostatitis. A four-to six-week course of the drugs typically does the trick. However, bacterial resistance to fluoroquinolones is a growing problem. An older drug called fosfomycin can help if other drugs stop working. PSA levels will decline with treatment, although that process may take three to six months.

CPPS is treated in other ways. Since it is not caused by a bacterial infection, CPPS will not respond to antibiotics. Medical treatments include nonsteroidal anti-inflammatory drugs such as ibuprofen, alpha blockers including tamsulosin (Flomax) that loosen tight muscles in the prostate and bladder neck, and drugs called PDEF inhibitors such as tadalafil (Cialis) that improve blood flow to the prostate.

Specialized types of physical therapy can provide some relief. One method called trigger point therapy, for instance, targets tender areas in muscles that tighten up and spasm. With another method called myofascial release, physical therapists can reduce tension in the connective tissues surrounding muscles and organs. Men should avoid Kegel exercises, however, which can tighten the pelvic floor and cause worsening symptoms.

Acupuncture has shown promise in clinical trials. One study published in 2023 showed significant improvements in CPPS symptoms lasting up to six months after the acupuncture treatments were finished. Mounting evidence suggest that CPPS should be treated with holistic strategies that also consider psychological factors.

Men with CPPS often suffer from depression, anxiety, and other mental health issues that can exacerbate pain perception. Techniques such as mindfulness and cognitive behavioral therapy for CPPS can help CPPS sufferers develop effective coping strategies.

Comment

“An accurate diagnosis is important given differences in how each of the four categories of prostatitis is treated,” said Dr. Boris Gershman, a urologist at Beth Israel Deaconess Medical Center and assistant professor of surgery at Harvard Medical School. PSA should also be retested after treating bacterial forms of prostatitis, Dr. Gershman added, to ensure that the levels go back to normal. If the PSA stays elevated after antibiotic treatment, or if abnormal levels are detected in men with nonbacterial prostatitis, then the PSA “should be evaluated in accordance with standard diagnostic approaches,” Dr. Gershman said.

Ever wonder if every medical test or treatment you've taken was truly necessary? Or are you inclined to get every bit of health care you can? Maybe you feel good about getting the most out of your health insurance. Perhaps a neighborhood imaging center is advertising discounted screening tests, your employer offers health screens as a perk, or you're intrigued by ads touting supplements for a seemingly endless number of conditions.

But keep in mind: just because you could get a particular test or treatment or take a supplement doesn't mean you should. One study suggests that as much as 20% of all health care in the US is unneeded. In short: when it comes to health care, more is not always better.

Isn't it better to be proactive about your health?

We're all taught that knowledge is power. So it might seem reasonable to want to know as much as possible about how your body is working. And isn't it better to take action before there's a problem rather than waiting for one to develop? What's the harm of erring on the side of more rather than less?

The truth is that knowledge is not always power: if the information is irrelevant to your specific situation, redundant, or inaccurate, the knowledge gained through unnecessary health care can be unhelpful or even harmful. Unnecessary tests, treatments, and supplements come with risks, even when they seem harmless. And, of course, unnecessary care is not free — even if you're not paying a cent out of pocket, it drives up costs across health systems.

Screening tests, wellness strategies, and treatments to reconsider

Recommended screening tests, treatments, and supplements can be essential to good health. But when risks of harm outweigh benefits — or if proof of any benefit is lacking — think twice. Save your time, money, and effort for health care that is focused on the most important health threats and backed by evidence.

Cancer screening: When to stop?

Screening tests for some cancers are routinely recommended and can be lifesaving. But there's a reason they come with a recommended stop age. For instance, guidelines recommend that a person at average risk of colorectal cancer with previously normal colonoscopies stop having them once they turn 75. Similar limits apply to Pap smears (age 65) and mammograms (age 75). Studies suggest that beyond those ages, there is little benefit to continuing these screens.

Watch out for wellness marketing

Dietary supplements are a multibillion-dollar industry. And a whopping 70% or more of US adults take at least one, such as vitamin D, fish oil, or a multivitamin. People often consider them as insurance in case vital elements are missing from their diet, or they believe supplements can prevent dementia, heart disease, or another condition.

Yet little evidence supports a benefit of routine supplement use for everyone. While recent studies suggest a daily multivitamin might slow cognitive decline in older adults, there's no medical consensus that everyone should be taking a multivitamin. Fish oil (omega-3) supplements haven't proven to be as healthful as simply eating servings of fatty fish and other seafood low in toxic chemicals like mercury and PCBs. And the benefits of routinely taking vitamin D supplements remain unproven as well.

It's worth emphasizing that dietary supplements clearly provide significant benefit for some people, and may be recommended by your doctor accordingly. For example, if you have a vitamin or mineral deficiency or a condition like age-related macular degeneration, good evidence supports taking specific supplements.

Reconsider daily aspirin

Who should be taking low-dose aspirin regularly? Recommendations have changed in recent years, so this is worth revisiting with your health care team.

• Older recommendations favored daily low-dose aspirin to help prevent cardiovascular disease, including first instances of heart attack and stroke.
• New recommendations favor low-dose aspirin for people who've already experienced a heart attack, stroke, or other cardiovascular disease. Adults ages 40 to 59 who are at a high risk for these conditions and low risk for bleeding also may consider it.

Yet according to a recent study, nearly one-third of adults 60 and older without past cardiovascular disease take aspirin, despite evidence that it provides little benefit for those at average or low risk. Aspirin can cause stomach bleeding and raise risk for a certain type of stroke.

Weigh in on prostate cancer screening

Men hear about prostate cancer often. It's common, and the second leading cause of cancer deaths among men. But PSA blood tests and rectal exams to identify evidence of cancer in the prostate are no longer routinely recommended for men ages 55 to 69 by the United States Preventative Services Task Force.

The reason? Studies suggest that performing these tests does not reliably reduce suffering or prolong life. Nor do possible benefits offset downsides like false positives (test results that are abnormal despite the absence of cancer). That can lead to additional testing, some of which is invasive.

Current guidelines suggest making a shared decision with your doctor about whether to have PSA testing after reviewing the pros and cons. For men over age 70, no screening is recommended. Despite this, millions of men have PSA tests and rectal examinations routinely.

Not everyone needs heart tests

There are now more ways than ever to evaluate the health of your heart. But none are routinely recommended if you're at low risk and have no signs or symptoms of cardiovascular disease. That's right: in the absence of symptoms or a high risk of cardiovascular disease, it's generally safe to skip EKGs, stress tests, and other cardiac tests.

Yet many people have these tests as part of their routine care. Why is this a problem? Having these tests without a compelling reason comes with risks, especially false positive results that can lead to invasive testing and unneeded treatment.

Four more reasons to avoid unnecessary care

Besides the concerns mentioned already, there are other reasons to avoid unnecessary care, including:

• The discomfort or complications of testing. If you're needle-phobic, getting a blood test is a big deal. And while complications of noninvasive testing are rare (such as a skin infection from a blood test), they can occur.
• The anxiety associated with waiting to find out test results
• False reassurance that comes with false negatives (results that are normal or nearly so, suggesting no disease when disease is actually present)
• All treatments have side effects. Even minor reactions — like occasional nausea or constipation — seem unacceptable if there's no reason to expect benefit from treatment.

The bottom line

You may believe your doctor wants you to continue with your current schedule of tests and treatments, while they might think this is your preference! It's worth discussing if you haven't already, especially if you suspect you may be taking pills or getting tests you don't truly need.

If your doctor says you can safely skip certain tests, treatments, and supplements, it doesn't mean that he or she is neglecting your health or that you don't deserve great health care! It's likely that the balance of risks and benefits simply doesn't support doing these things.

Less unnecessary care could free up resources for those who need it most. And it could save you time, money, and unnecessary risks or side effects, thus improving your health. It's a good example of how less can truly be more.

Most men over 50 will develop an enlarged prostate. Also called benign prostatic hyperplasia (BPH), this bothersome condition makes it hard to urinate and can eventually lead to other problems, such as infections, kidney stones, and bladder damage, if left untreated. Many different BPH therapies are available, including medications and various types of surgery.

One of the newer surgical options, called aquablation, trims excess prostate tissues with highly pressurized jets of saline. Doctors perform aquablation in the operating room while looking at the prostate gland on an ultrasound machine. Patients are put under general anesthesia, so they don’t feel any pain during the procedure.

Men typically have to urinate through a catheter for about 24 hours after surgery until swelling of the urethra (the tube through which urine flows out of the bladder) subsides. Aquablation is gaining in popularity — in part because, unlike other more traditional BPH treatments, it can preserve normal ejaculation.

In September, researchers published a study showing that improvements in urinary function from aquablation were still holding up after five years.

Results of data analysis

The study assessed long-term data from two clinical trials. The first, called the WATER trial (for Waterjet Ablation Therapy for Endoscopic Resection of Prostate Tissue) launched in 2015 and enrolled 116 men with prostates ranging up to 80 cubic centimeters. The second trial, WATER II, launched in 2017 and enrolled 101 men with prostates ranging between 80 and 150 cubic centimeters. (Normal prostates range from 25 to 30 cubic centimeters in size.) Enrolled patients had a median age of 66 in the WATER study and 68 in WATER II. In addition, 92% of men in the WATER trial were sexually active, as were 75% of the men in WATER II.

Both clinical trials used the so-called International Prostate Symptom Score (IPSS) to measure treatment-related improvements in urinary functioning and quality of life. Calculated based on how patients rate their symptoms on a standardized questionnaire, IPSS scores fall into three categories: mild symptom scores range from 1 to 7; intermediate symptom scores range from 8 to 18; and scores greater than 19 indicate severe symptoms.

When they first enrolled in the trials, men in the WATER and WATER II studies reported average IPSS scores of 22.9 and 23.3 respectively. Five years later, the average respective scores were much lower: 7.0 and 6.8. The average length of hospital stay was 1.4 days in the WATER group and 1.6 days for the WATER II group. Only 1% of men were taking BPH medications after five years, and fewer than 5% had been surgically re-treated.

Another randomized control trial, WATER III, is currently underway in Europe. That trial compares aquablation with a more established type of BPH surgery, prostate enucleation, which uses a laser to remove obstructing tissues. Six-month data reported in 2023 showed that men in either group had comparable symptom improvements.

However, 98% of men in the prostate enucleation group had ejaculatory dysfunction. That side effect is caused by damage to delicate tissues around the bladder neck that propel semen out of the body. Semen therefore flows back into the bladder, a condition called retrograde ejaculation. None of the men in the aquablation group reported ejaculatory problems.

A word of caution

Aquablation can result in extended bleeding, cautions Dr. Heidi Rayala, an assistant professor of urology at Harvard Medical School and a member of the Harvard Medical School Guide to Prostate Diseases advisory board. That’s because unlike other types of surgery for BPH, including prostate enucleation, aquablation doesn’t cauterize tissues with heat. “I tell my patients to expect some blood in the urine for about four to six weeks after the procedure,” Dr. Rayala said.

Moreover, aquablation may be unsuitable for some men who take blood thinners to prevent blood from clotting, according to Dr. Rayala. Appropriate candidates for the surgery must be able to “safely discontinue anticoagulant medications during post-operative healing, given the bleeding risk,” Dr. Rayala said. Still, aquablation is an excellent option for most men, Dr. Rayala said, especially those with medium to large prostates “who want a durable solution with a lower risk of sexual side effects.”

“These early results are encouraging, but limited by a relatively small number of patients,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases. “Further evidence with a significantly larger number of patients and longer follow-up will help to support this new method of reducing prostate tissue as an important treatment option.”

By the time boys are 8 or 10, they’re steeped in Marvel action heroes with bulging, oversized muscles and rock-hard abs. By adolescence, they’re deluged with social media streams of bulked-up male bodies.

The underlying messages about power and worth prompt many boys to worry and wonder about how to measure up. Sometimes, negative thoughts and concerns even interfere with daily life, a mental health issue known body dysmorphic disorder, or body dysmorphia. The most common form of this in boys is muscle dysmorphia.

What is muscle dysmorphia?

Muscle dysmorphia is marked by preoccupation with a muscular and lean physique. While the more extreme behaviors that define this disorder appear only in a small percentage of boys and young men, it may color the mindset of many more.

Nearly a quarter of boys and young men engage in some type of muscle-building behaviors. “About 60% of young boys in the United States mention changing their diet to become more muscular,” says Dr. Gabriela Vargas, director of the Young Men’s Health website at Boston Children’s Hospital. “While that may not meet the diagnostic criteria of muscle dysmorphia disorder, it’s impacting a lot of young men.”

“There’s a social norm that equates muscularity with masculinity,” Dr. Vargas adds. “Even Halloween costumes for 4- and 5-year-old boys now have padding for six-pack abs. There’s constant messaging that this is what their bodies should look like.”

Does body dysmorphic disorder differ in boys and girls?

Long believed to be the domain of girls, body dysmorphia can take the form of eating disorders such as anorexia or bulimia. Technically, muscle dysmorphia is not an eating disorder. But it is far more pervasive in males — and insidious.

“The common notion is that body dysmorphia just affects girls and isn’t a male issue,” Dr. Vargas says. “Because of that, these unhealthy behaviors in boys often go overlooked.”

What are the signs of body dysmorphia in boys?

Parents may have a tough time discerning whether their son is merely being a teen or veering into dangerous territory. Dr. Vargas advises parents to look for these red flags:

• Marked change in physical routines, such as going from working out once a day to spending hours working out every day.
• Following regimented workouts or meals, including limiting the foods they’re eating or concentrating heavily on high-protein options.
• Disrupting normal activities, such as spending time with friends, to work out instead.
• Obsessively taking photos of their muscles or abdomen to track “improvement.”
• Weighing himself multiple times a day.
• Dressing to highlight a more muscular physique, or wearing baggier clothes to hide their physique because they don’t think it’s good enough.

“Nearly everyone has been on a diet,” Dr. Vargas says. “The difference with this is persistence — they don’t just try it for a week and then decide it’s not for them. These boys are doing this for weeks to months, and they’re not flexible in changing their behaviors.”

What are the health dangers of muscle dysmorphia in boys?

Extreme behaviors can pose physical and mental health risks.

For example, unregulated protein powders and supplements boys turn to in hopes of quickly bulking up muscles may be adulterated with stimulants or even anabolic steroids. “With that comes an increased risk of stroke, heart palpitations, high blood pressure, and liver injury,” notes Dr. Vargas.

Some boys also attempt to gain muscle through a “bulk and cut” regimen, with periods of rapid weight gain followed by periods of extreme calorie limitation. This can affect long-term muscle and bone development and lead to irregular heartbeat and lower testosterone levels.

“Even in a best-case scenario, eating too much protein can lead to a lot of intestinal distress, such as diarrhea, or to kidney injury, since our kidneys are not meant to filter out excessive amounts of protein,” Dr. Vargas says.

The psychological fallout can also be dramatic. Depression and suicidal thoughts are more common in people who are malnourished, which may occur when boys drastically cut calories or neglect entire food groups. Additionally, as they try to achieve unrealistic ideals, they may constantly feel like they’re not good enough.

How can parents encourage a healthy body image in boys?

These tips can help:

• Gather for family meals. Schedules can be tricky. Yet considerable research shows physical and mental health benefits flow from sitting down together for meals, including a greater likelihood of children being an appropriate weight for their body type.
• Don’t comment on body shape or size. “It’s a lot easier said than done, but this means your own body, your child’s, or others in the community,” says Dr. Vargas.
• Frame nutrition and exercise as meaningful for health. When you talk with your son about what you eat or your exercise routine, don’t tie hoped-for results to body shape or size.
• Communicate openly. “If your son says he wants to exercise more or increase his protein intake, ask why — for his overall health, or a specific body ideal?”
• Don’t buy protein supplements. It’s harder for boys to obtain them when parents won’t allow them in the house. “One alternative is to talk with your son’s primary care doctor or a dietitian, who can be a great resource on how to get protein through regular foods,” Dr. Vargas says.

Animals renowned for their outstanding night vision include owls, cats, tarsiers (a tiny primate in Southeast Asia) — and even the dung beetle.

But humans? Not so much.

Over time, many people suffer from night blindness, also known as nyctalopia. This condition makes seeing in dim or dark settings difficult because your eyes cannot adjust to changes in brightness or detect light.

What are the dangers for those experiencing night blindness?

Night blindness is especially problematic and dangerous when driving. Your eyes cannot adjust between darkness and the headlights of oncoming vehicles, other cars may appear out of focus, and your depth perception becomes impaired, which makes it difficult to judge distances.

Night blindness also may affect your sight at home by making it hard for your vision to quickly adjust to a dark room after turning off the lights. “This can cause people to bump into furniture or trip and suffer an injury,” says Dr. Isabel Deakins, an optometrist with Harvard-affiliated Massachusetts Eye and Ear.

What happens in the eye to create night blindness?

The ability to see in low-light conditions involves two structures in the eye: the retina and the iris.

The retina, located in the back of the eye, contains two types of light-detecting cells called cones and rods. The cones handle color vision and fine details while the rods manage vision in dim light.

The iris is the colored part of your eye. It contains muscles that widen or narrow the opening of your pupil to adjust how much light can enter your eyes.

If your irises don’t properly react, the pupils can dilate and let in too much light, which causes light sensitivity and makes it hard to see in bright light. Or your pupils may remain too small and not allow in enough light, making it tough to see in low light.

What causes night blindness?

Night blindness is not a disease but a symptom of other conditions. “It’s like having a bruise on your body. Something else causes it,” says Dr. Deakins.

Several conditions can cause night blindness. For instance, medications, such as antidepressants, antihistamines, and antipsychotics, can affect pupil size and how much light enters the eye.

Eye conditions that can cause night blindness include:

• glaucoma, a disease that damages the eye’s optic nerves and blood vessels
• cataracts, cloudy areas in the lens that distort or block the passage of light through the lens
• dry eye syndrome.

However, one issue that raises the risk of night blindness that you can’t control is age. “Our eyes react more slowly to light changes as we age, and vision naturally declines over time,” says Dr. Deakins.  “The number of rods in our eyes diminish, pupils get smaller, and the muscles of the irises weaken.”

What helps if you have night blindness?

If you notice any signs of night blindness, avoid driving and get checked by an eye care specialist like an optometrist or ophthalmologist. An eye exam can determine if your eyeglass prescription needs to be updated.

“Often, a prescription change is enough to reduce glare when driving at night," says Dr. Deakins. “You may even need separate glasses with a stronger eye prescription that you wear only when driving at night.”

Adding an anti-reflective coating to your lens may help to cut down on the glare of the headlights of an oncoming car. However, skip the over-the-counter polarized driving glasses sold at many drug stores. "These may help cut down on glare, but they don't address the causes of night blindness," says Dr. Deakins.

An eye exam also will identify glaucoma or cataracts, which can be treated. Glaucoma treatments include eyedrops, laser treatment, or surgery. Cataracts are corrected with surgery to replace the clouded lens with an artificial one. Your eye care specialist can also help identify dry eye and recommend treatment.

Ask your primary care clinician or a pharmacist if any medications that you take may cause night blindness. If so, it may be possible to adjust the dose or switch to another drug.

Three more ways to make night driving safer

You also can take steps to make night driving safer. For example:

• Wash the lenses of your glasses regularly. And take them to an optician to buff out minor scratches.
• Keep both sides of your front and rear car windshields clean so that you can see as clearly as possible.
• Dim your dashboard lights, which cause glare, and use the night setting on your rearview mirror.

Let’s face it: inflammation has a bad reputation. Much of it is well-deserved. After all, long-term inflammation contributes to chronic illnesses and deaths. If you just relied on headlines for health information, you might think that stamping out inflammation would eliminate cardiovascular disease, cancer, dementia, and perhaps aging itself.

Unfortunately, that’s not true.

Still, our understanding of how chronic inflammation can impair health has expanded dramatically in recent years. And with this understanding come three common questions: Could I have inflammation without knowing it? How can I find out if I do? Are there tests for inflammation? Indeed, there are.

Testing for inflammation

A number of well-established tests to detect inflammation are commonly used in medical care. But it’s important to note these tests can't distinguish between acute inflammation, which might develop with a cold, pneumonia, or an injury, and the more damaging chronic inflammation that may accompany diabetes, obesity, or an autoimmune disease, among other conditions. Understanding the difference between acute and chronic inflammation is important.

These are four of the most common tests for inflammation:

• Erythrocyte sedimentation rate (sed rate or ESR). This test measures how fast red blood cells settle to the bottom of a vertical tube of blood. When inflammation is present the red blood cells fall faster, as higher amounts of proteins in the blood make those cells clump together. While ranges vary by lab, a normal result is typically 20 mm/hr or less, while a value over 100 mm/hr is quite high.
• C-reactive protein (CRP). This protein made in the liver tends to rise when inflammation is present. A normal value is less than 3 mg/L. A value over 3 mg/L is often used to identify an increased risk of cardiovascular disease, but bodywide inflammation can make CRP rise to 100 mg/L or more.
• Ferritin. This is a blood protein that reflects the amount of iron stored in the body. It’s most often ordered to evaluate whether an anemic person is iron-deficient, in which case ferritin levels are low. Or, if there is too much iron in the body, ferritin levels may be high. But ferritin levels also rise when inflammation is present. Normal results vary by lab and tend to be a bit higher in men, but a typical normal range is 20 to 200 mcg/L.
• Fibrinogen. While this protein is most commonly measured to evaluate the status of the blood clotting system, its levels tend to rise when inflammation is present. A normal fibrinogen level is 200 to 400 mg/dL.

Are tests for inflammation useful?

In certain situations, tests to measure inflammation can be quite helpful.

• Diagnosing an inflammatory condition. One example of this is a rare condition called giant cell arteritis, in which the ESR is nearly always elevated. If symptoms such as new, severe headache and jaw pain suggest that a person may have this disease, an elevated ESR can increase the suspicion that the disease is present, while a normal ESR argues against this diagnosis.
• Monitoring an inflammatory condition. When someone has rheumatoid arthritis, for example, ESR or CRP (or both tests) help determine how active the disease is and how well treatment is working.

None of these tests is perfect. Sometimes false negative results occur when inflammation actually is present. False positive results may occur when abnormal test results suggest inflammation even when none is present.

Should you be routinely tested for inflammation?

Currently, tests of inflammation are not a part of routine medical care for all adults, and expert guidelines do not recommend them.

CRP testing to assess cardiac risk is encouraged to help decide whether preventive treatment is appropriate for some people (such as those with a risk of a heart attack that is intermediate — that is, neither high nor low). However, for most people evidence suggests that routine CRP testing adds relatively little to assessment using standard risk factors, such as a history of hypertension, diabetes, smoking, high cholesterol, and positive family history of heart disease.

So far, only one group I know of recommends routine testing for inflammation for all without a specific reason: companies selling inflammation tests directly to consumers.

Inflammation may be silent — so why not test?

It’s true that chronic inflammation may not cause specific symptoms. But looking for evidence of inflammation through a blood test without any sense of why it might be there is much less helpful than having routine health care that screens for common causes of silent inflammation, including

• excess weight
• diabetes
• cardiovascular disease (including heart attacks and stroke)
• hepatitis C and other chronic infections
• autoimmune disease.

Standard medical evaluation for most of these conditions does not require testing for inflammation. And your medical team can recommend the right treatments if you do have one of these conditions.

The bottom line

Testing for inflammation has its place in medical evaluation, and in monitoring certain health conditions such as rheumatoid arthritis. But it’s not clearly helpful as a routine test for everyone. A better approach is to adopt healthy habits and get routine medical care that can identify and treat the conditions that contribute to harmful inflammation.

Roughly one in six men will be diagnosed with prostate cancer at some point in their lives, but these cancers usually aren’t life-threatening. Most newly diagnosed men have Grade Group 1 (GG1) prostate cancer, which can linger for years without causing significant harms.

Prostate cancer is categorized according to how far it has spread and how aggressive it looks under the microscope. Pure GG1 prostate cancer is the least risky form of the disease. It occurs frequently with age, will not metastasize to other parts of the body, and it doesn’t require any immediate treatment.

So, should we even call it cancer? Many experts say no.

Dr. Matthew Cooperberg, who chairs the department of urology at the University of California, San Francisco, says men wouldn’t suffer as much anxiety — and would be less inclined to pursue unneeded therapies — if their doctors stopped referring to low-grade changes in the prostate as cancer. He recently co-chaired a symposium where experts from around the world gathered to discuss the pros and cons of giving GG1 cancer another name.

Treatment discrepancies

GG1 cancer is typically revealed by PSA screening. The goal with screening is to find more aggressive prostate cancer while it’s still curable, yet these efforts often detect GG1 cancer incidentally. Attendees at the symposium agreed that GG1 disease should be managed with active surveillance. With this standard practice, doctors monitor the disease with periodic PSA checks, biopsies, and imaging, and treat the disease only if it shows signs of progression.

But even as medical groups work to promote active surveillance, 40% of men with low-risk prostate cancer in the United States are treated immediately. According to Dr. Cooperberg, that’s in part because the word “cancer” has such a strong emotional impact. “It resonates with people as something that spreads and kills,” he says. “No matter how much we try to get the message out there that GG1 cancer is not an immediate concern, there’s a lot of anxiety associated with a ‘C-word’ diagnosis.”

A consequence is widespread overtreatment, with tens of thousands of men needlessly suffering side effects from surgery or radiation every year. A cancer diagnosis has other harmful consequences: studies reveal negative effects on relationships and employment as well as “someone’s ability to get life insurance,” Dr. Cooperberg says. “It can affect health insurance rates.”

Debate about renaming

Experts at the symposium proposed that GG1 cancer could be referred to instead as acinar neoplasm, which is an abnormal but nonlethal growth in tissue. Skeptics expressed a concern that patients might not stick with active surveillance if they aren’t told they have cancer. But should men be scared into complying with appropriate monitoring? Dr. Cooperberg argues that patients with pure GG1 “should not be burdened with a cancer diagnosis that has zero capacity to harm them.”

Dr. Cooperberg does caution that since biopsies can potentially miss higher-grade cancer elsewhere in the prostate, monitoring the condition with active surveillance is crucial. Moreover, men with a strong family history of cancer, or genetic mutations such as BRCA1 and BRCA2 that put them at a higher risk of aggressive disease, should be followed more closely, he says.

Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases, agrees. Dr. Garnick emphasized that a name change for GG1 cancer needs to consider a wide spectrum of additional testing. “This decision can’t simply be based on pathology,” he says. “Biopsies only sample a miniscule portion of the prostate gland. Genetic and genomic tests can help us identify some low-risk cancers that might behave in a more aggressive fashion down the road.”

Meanwhile, support for a name change is gaining momentum. “Younger pathologists and urologists are especially likely to think this is a good idea,” Dr. Cooperberg says. “I think the name change is just a matter of time — in my view, we’ll get there eventually.”

Has the recent news about measles outbreaks in the US surprised you? Didn’t it seem like we were done with measles?

In the US, widespread vaccination halted the ongoing spread of measles more than 20 years ago, a major public health achievement. Before an effective vaccine was developed in the 1960s, nearly every child in the US got measles. Complications like measles-related pneumonia or hearing loss were common, and 400 to 500 people died each year.

As I write this, there have been 800 confirmed cases in 24 states, mostly among children. The biggest outbreak is in west Texas, where 62 people have been hospitalized and two unvaccinated school-age children recently died, the first measles deaths in the US since 2015. Officials in New Mexico have also reported a measles-related death.

Can we prevent these tragedies?

Measles outbreaks are highly preventable. It’s estimated that when 95% of people in a community are vaccinated, both those individuals and others in their community are protected against measles.

But nationally, measles vaccination rates among school-age kids fell from 95% in 2019 to 92% in 2023. Within Texas, the kindergarten vaccination rates have dipped below 95% in about half of all state counties. In the community at the center of the west Texas outbreak, the reported rate is 82%. Declining vaccination rates are common in other parts of the US, too, and that leaves many people vulnerable to measles infections.

Only 2% of the recent cases in the US involved people known to be fully vaccinated. The rest were either unvaccinated or had unknown vaccine status (96%), or they had received only one of the two vaccine doses (1%).

What to know about measles

As measles outbreaks occur within more communities, it’s important to understand why this happens — and how to stop it. Here are seven things to know about measles.

The measles virus is highly contagious

Several communities have suffered outbreaks in recent years. The measles virus readily spreads from person to person through the air we breathe. It can linger in the air for hours after a sneeze or cough. Estimates suggest nine out of 10 nonimmune people exposed to measles will become infected. Measles is far more contagious than the flu, COVID-19, or even Ebola.

Early diagnosis is challenging

It usually takes seven to 14 days for symptoms to show up once a person gets infected. Common early symptoms — fever, cough, runny nose — are similar to other viral infections such as colds or flu. A few days into the illness, painless, tiny white spots in the mouth (called Koplik spots) appear. But they’re easy to miss, and are absent in many cases. A day or two later, a distinctive skin rash develops.

Unfortunately, a person with measles is highly contagious for days before the Koplik spots or skin rash appear. Very often, others have been exposed by the time measles is diagnosed and precautions are taken.

Measles can be serious and even fatal

Measles is not just another cold. A host of complications can develop, including

• brain inflammation (encephalitis), which can lead to seizures, hearing loss, or intellectual disability
• pneumonia
• eye inflammation (and occasionally, vision loss)
• poor pregnancy outcomes, such as miscarriage
• subacute sclerosing panencephalitis (SSPE), a rare and lethal disease of the brain that can develop years after the initial measles infection.

Complications are most common among children under age 5, adults over age 20, pregnant women, and people with an impaired immune system. Measles is fatal in up to three of every 1,000 cases.

During the latest outbreaks, 85 cases —nearly one in nine — have required hospitalization.

Getting measles may suppress your immune system

When you get sick from a viral or bacterial infection, antibodies created by your immune system will later recognize and help mount a defense against these intruders. In 2019, a study at Harvard Medical School (HMS) found that the measles virus may wipe out up to three-quarters of antibodies protecting against viruses or bacteria that a child was previously immune to — anything from strains of the flu to herpesvirus to bacteria that cause pneumonia and skin infections.

“If your child gets the measles and then gets pneumonia two years later, you wouldn’t necessarily tie the two together. The symptoms of measles itself may be only the tip of the iceberg,” said the study’s first author, Dr. Michael Mina, who was a postdoctoral researcher in the laboratory of geneticist Stephen Elledge at HMS and Brigham and Women’s Hospital at the time of the study.

In this video, Mina and Elledge discuss their findings.

Vaccination is highly effective

Two doses of the current vaccine provide 97% protection — much higher than most other vaccines.  Rarely, a person gets measles despite being fully vaccinated. When that happens, the disease tends to be milder and less likely to spread to others.

The measles vaccine is safe

 The safety profile of the measles vaccine is excellent. Common side effects include temporary soreness in the arm, low-grade fever, and muscle pain, as is true for most vaccinations. A suggestion that measles or other vaccines cause autism has been convincingly discredited. However, this often-repeated misinformation has contributed to significant vaccine hesitancy and falling rates of vaccination.

Ways to protect yourself from measles infection

• Vaccination. Usually, children are given the first dose around age 1 and the second between ages 4 and 6 as part of the Measles-Mumps-Rubella (MMR) vaccine. If a child — or adult — hasn’t been vaccinated, they can have these doses later.

  If you were born after 1957 and received a measles vaccination before 1968, consider getting revaccinated or tested for measles antibodies (see below). The vaccine given before 1968 was less effective than later versions. And before 1957, most people became immune after having measles, although this immunity can wane.

• Isolation. To limit spread, everyone diagnosed with measles and anyone who might be infected should avoid close contact with others until four days after the rash resolves.
• Mask-wearing by people with measles can help prevent spread to others. Household members or other close contacts should also wear a mask to avoid getting it.
• Frequent handwashing helps keep the virus from spreading.
• Testing. If you aren’t sure about your measles vaccination history or whether you may be vulnerable to infection, consider having a blood test to find out if you’re immune to measles. Memories about past vaccinations can be unreliable, especially if decades have gone by, and immunity can wane.
• Pre-travel planning. If you are headed to a place where measles is common, make sure you are up to date with vaccinations.

The bottom line

While news about measles in recent months may have been a surprise, it’s also alarming. Experts warn that the number of cases (and possibly deaths) are likely to increase. And due to falling vaccination rates, outbreaks are bound to keep occurring. One study estimates that between nine and 15 million children in the US could be susceptible to measles.

But there’s also good news: we know that measles outbreaks can be contained and the disease itself can be eliminated. Learn how to protect yourself and your family. Engage respectfully with people who are vaccine hesitant: share what you’ve learned from reliable sources about the disease, especially about the well-established safety of vaccination.
