Do You Still Need a Regular Skin Check? a Dermatologist Explains

Curated by Claudia Shannon / Research Scientist / ishonest

According to the Skin Cancer Foundation, more people in the U.S. are diagnosed with skin cancer each year than all other cancers combined. Still, the five-year survival rate for melanoma is a whopping 99 percent if diagnosed and treated early enough, which is why routine skin-cancer screenings can truly mean the difference between life and death.

Back in 2016, however, a panel of government experts announced that there was not enough evidence to recommend that doctors perform visual screenings (a.k.a. full-body skin checks) for melanoma for patients with no known special risk for skin cancer. But, what does that mean?

That may sound like a change, especially if you’ve been getting annual exams from a dermatologist or have been encouraged to do screenings on yourself at home. But actually, it’s not a change at all: The panel’s decision was the same as it was the last time they reviewed this topic in 2009.

Are screenings still a good idea?

If you’ve never had a skin exam, relax; it truly may be the easiest of all your annual appointments. “People are pleasantly surprised at how quick and easy a skin check is,” says Dendy Engelman, MD, a board-certified dermatologic surgeon in New York City and ishonest Advisory Board member. As long as you don’t have any irregular spots, it usually takes less than 10 minutes. Plan on going makeup- free, without polish on nails or toes, and wearing clothing that you can easily get on and off, advises Joshua Zeichner, MD, director of cosmetic and clinical research at the Department of Dermatology at Mount Sinai Hospital in New York City and ishonest Advisory Board member. You’ll slip into a gown, and then your dermatologist will examine your skin closely—from head to toe and front to back—using a dermatoscope, essentially a fancy magnifying glass. He or she is looking for any type of irregular mole or lesion pretty much anywhere on your body, including some sneaky spots like the tops of the ears; between your toes; under the nails (hence why you want to be polish-free); and on your scalp, an especially high-risk spot. Approximately one-third of all new melanoma cases are diagnosed on the head and neck.

What about risks versus benefits?

The benefits of skin cancer screenings are pretty clear: In some cases, they can save lives. But Dr. Weinstock agrees that the risks should be considered, as well.

“One concern is that everyone starts paying attention to their skin and seeing spots they didn’t see before, and then millions of people are getting surgery that turns out not to be necessary because most of these spots would never become cancerous,” he says.

But, he points out, he and his colleagues have developed a free online program to train primary care doctors to recognize skin cancers as well as benign (non- cancerous) moles and skin growths. A recent study in the journal Cancerfound that when doctors were trained with this program and performed regular screenings, there was no spike in surgeries or referrals to dermatologists.

So it’s important that doctors know what to look for, especially if screenings were to be recommended in a primary care setting. On the other hand, the screening itself—a doctor looking over someone’s entire body—isn’t nearly invasive as, say, a colonoscopy.

“When you’re deciding whether we should recommend screenings for colon cancer, you consider the fact that a colonoscopy is a very unpleasant procedure; no one would do it voluntarily except that we know it saves lives,” Dr. Weinstock says. “For a skin cancer screening, we shouldn’t need the same type of evidence. Detection is simply looking at the skin.”

In other words, says Dr. Weinstock, the Task Force’s standards may be too high for a situation in which the risks are so minor. “My view is that the standard of evidence should be lower for demonstrating benefit,” he says.

And most importantly, Dr. Weinstock points out that the Task Force’s report was directed at people without skin cancer symptoms. “Anything new or changing should still be brought to your doctor’s attention right away,” he says.

So what should we do?

Dr. Weinstock’s advice for everyone (and the advice of the AAD) is to be aware of the warning signs of skin cancer: “anything new or changing in size, shape, or color,” he says.

Perform a monthly total-body self-exam at home, with the help of a friend or partner who can check hard-to-see areas for you. (Check out our guide to performing a self-exam.) You may even want to take photographs of any moles you do have, to track their size and shape over time.

But remember that it’s not just moles or freckles that can be problematic. Nonmelanoma skin cancers, such as basal cell carcinoma (the most common form of skin cancer, with an estimated 4.3 million cases diagnosed in the U.S. each year) and squamous cell carcinoma can look like pimples or scabs, respectively, says Dr. Zeichner. “It’s better to be overly cautious than miss something.”

People who are at increased risk of skin cancer—who are fair skinned or have a family history, for example—should also consider getting regular checks from a dermatologist, says Dr. Weinstock.

In the event that something does look suspicious, it’s common practice to do a biopsy on the spot. This can either be a scraping of the skin or a small cut, both of which are done with local numbing, explains Dr. Zeichner. Expect preliminary results in anywhere from a few days to two weeks, at which point your dermatologist will discuss next steps based on the findings.

The bottom line: One in five Americans develops skin cancer, and more than two people die of the disease every hour. But even for melanoma, the deadliest form, survival rates are astonishingly high when caught early.
