A young friend with a receding hairline recently asked if bald men are more likely to get skin cancer on their scalps.
Unfortunately, the answer is yes, skin cancers are more often diagnosed on scalps of men who are bald than those who are not.
However, according to an article by Dr. Ida Orengo, professor of dermatology at Baylor College of Medicine and director of the Mohs Surgery Center at the Baylor Clinic in Houston, a full head of hair does not necessarily protect you from getting skin cancer on the scalp. "Dark thick hair gives more protection compared to blond wispy locks, but some type of extra protection should be used at all times."
All types of skin cancers can be diagnosed on the scalp. The three most common are squamous, basal and melanoma. And, unfortunately, a study by researchers at the University of North Carolina at Chapel Hill (Arch Dermatol. 2008;144(4): 515-521) have found that people with scalp or neck melanomas die at nearly twice the rate of people with melanoma elsewhere on the body, including the face or ears. Further, the study found that patients with scalp or neck melanomas were older (59 years) than patients with other melanomas (55 years), and more likely to be male (74 percent versus 54 percent, respectively. In addition, scalp and neck melanomas were thicker (0.8 millimeters) than melanomas at other sites (0.6 millimeters) and more likely to be ulcerated. Lymph node involvement was also more common for patients with scalp or neck melanoma.
Protect your scalp by wearing a hat with a three-inch brim made with materials that have been tested for UPF levels. This is part of the SunAWARE advice - W - Wear sun protective clothing including a hat with a three inch brim and sunglasses.
The best hats have tags showing a rating of UPF 50+. Do not rely on shampoos and conditioners that include SPF ingredients. While these may help, protection will be uneven, and you are not likely to "reapply" every two hours while exposed. Further, remember to check your scalp when you routinely check your skin.
How to Check Your Scalp:
Catherine Poole at the Melanoma International Foundation emphasizes the importance of checking your scalp as part of R in SunAWARE- Routinely check your skin, understand your need for vitmin D, and report any concerns to a health care provider.
Using a hair dryer and a comb, make parts through your hair - one row at a time - over the top of your head and down to your ears to check for any lesion covered by hair. You can check the back of your head using a hand held mirror, but this is cumbersome. Ask someone to help. (Checks made by hairdressers or other members of your family are helpful) Make notes.
Be SunAWARE. Be Safe.
