15 Skin Cancer Myths You Need to Stop Believing Right Now
That sun-kissed glow may actually be the kiss of cancer. Here are the myths people believe that could raise your risk of skin cancer.
I tan and never burn—why should I worry?
“A big skin cancer myth is that people who tan effortlessly without burning will not get skin cancer. That is absolutely false. We see cancer in patients of all skin types. Already having a dark tan, or dark skin that doesn’t appear to burn, is not enough to protect you,” says Monica L. Halem, MD, founder and medical director for the New York Dermatologic Surgery Cosmetic Laser Center. Tanning may look healthy, but it is always an indication of skin damage. According to the Centers for Disease Control and Prevention (CDC), tanning is the skin’s response to injury. Skin cells signal that they have become damaged by producing melanin (additional skin pigment). So the next time you decide to go for that gorgeous goddess look, consider a faux-glow instead. Check out these sunscreen tips you should always follow to protect your skin.
Tanning salons are a safe way to tan
Wrong. “One visit to an indoor tanning bed before age 35 can increase your risk of melanoma, the most dangerous type of skin cancer, by more than 50 per cent,” says Joslyn M. Albright, MD, who specializes in surgical oncology, breast cancer, and melanoma at Advocate Christ Medical Center in Chicago. One study reported in the Journal of Clinical Oncology followed 73,494 female nurses for 20 years and found that tanning bed use increased the risk for three types of skin cancer: malignant melanoma, basal cell carcinoma, and squamous cell carcinoma. As a result of this study and of others like it, the researchers concluded that policymakers should pass and enforce restrictions on the indoor tanning industry.
Skin cancer is limited to skin
Your eyes can get sunburned, too, and they can develop ocular melanoma, a kind of cancer which forms in cells that produce pigment in or around your eyes. “Just as exposure to UV rays damage the skin in the form of sunburn, they can also harm the eyes or affect vision. However, 94 per cent of people don’t realize the sun can be just as harmful to their eyes as it is to their skin,” says Ryan Parker, OD, optometrist and optometric consultant with Essilor of America.
According to Dr. Parker, if your eyes are exposed to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis, or “sunburn of the eye,” a painful health condition which includes symptoms such as red eyes, a feeling like grit in your eyes, extreme sensitivity to light, and excessive tearing. As with your skin, repeated intense exposure can lead to cancer; the risk is higher for people with light-coluored eyes. Dr. Parker also suggests rethinking that seemingly blissful plan, to fall asleep in the sun without sunglasses on. “According to The Skin Cancer Foundation, skin cancer on the eyelid accounts for 5 to 10 per cent of all skin cancers,” he adds.
It’s worth the extra money for high SPF sunscreens
The SPF—sun protection factor—on sunscreens and other products can be misleading. Here’s how it works: A product with an SPF of 100 theoretically allows you to stay out in the sun, and not burn, 100 times longer than you would without it. However, you still need to reapply it if you sweat or get wet to gain protection. People also tend to use less quantity of high-SPF sunscreens than they might those with lower SPF when they’re slathering them on.
A sunscreen with 15 SPF will screen out 93 per cent of the sun’s UVB rays, explains general pediatrician Andrette Ward, MD, of White Memorial Community Health Center. “An SPF of 30 screens out 97 per cent. An SPF of 50, 98 per cent,” she says. “Appropriate use of sunscreen with an SPF of 30 is sufficient for protection from harmful UV radiation. Sunscreens with an SPF higher than 50 do not provide any additional protection from UVB radiation. They may also not provide enough screening for UVA radiation.” According to the Environmental Working Group’s Guide to Sunscreens, products with SPF 50 or above simply don’t do a great job at blocking UVA rays. Those are the ones most associated with malignant melanoma, the deadliest form of skin cancer. Save your money and stay in the 30-50 SPF range. Believe it or not, these 10 foods can boost your skin’s SPF.
There’s not much I can do to protect myself from UVA rays
According to Dr. Halem, the best, most complete UVA ray blocker is still zinc. But let memories of lifeguards with white paste on their nose make you panic: “Zinc now goes on clear,” she says. There are many sheer zinc products on the market. Look for those that contain at least 20 per cent zinc oxide, or a combination of 15 per cent zinc oxide coupled with titanium dioxide to provide the best protection from UVAs. Zinc oxide is not absorbed into the skin, making it an excellent choice for children’s sun protection. Here are six more reasons to switch to zinc oxide or another mineral sunscreen this summer.
Tanning as a child protects you from skin cancer as an adult
“This is one of the biggest skin cancer myths there is. Many people believe that large amounts of early sun exposure desensitizes children to skin cancer and sun damage when they grow up. In actuality, the opposite is true,” says Dr. Ward. Lots of sun exposure during childhood only adds to your lifelong sun damage and skin cancer risk.
If it’s winter, I can ease up on the sunscreen
Winter sports enthusiasts take note—whether it’s summer or winter, hot or cold, the sun is still the sun. “You are exposed to UV rays even in the winter, especially if you ski at high altitudes,” says Dr. Halem. According to Rewire, UV rays may pose additional threats come the winter months because they reflect off snow and ice. If you’ve ever found yourself squinting outside in the bright, white snow, you’ll know that protecting your eyes under sunglasses during winter months is important, too. This might help explain the rise of skin cancer in Canada.
If I can’t see the sun, I’m safe
An overcast day is no protection. “UV rays can stream right through the clouds,” explains Dr. Albright. In fact, according to The Skin Cancer Foundation, a full 80 per cent of UV rays can make it through cloud cover. If you’re vain about your skin, whether it’s overcast or sunny, make sure to slather up any exposed areas when you go outside.
These are the 13 signs of cancer men are likely to ignore.
My child and I have dark skin, so we don’t have to worry about skin cancer
People of colour can get skin cancer, although their risk is lower than lighter skinned individuals, according to the CDC. All children require protection from UV rays, though: “Infants and toddlers of colour have less melanin in their skin than they will eventually have when they are grown. For that reason, they have less skin protection from UV rays as children than they will as adults,” explains Dr. Ward. Remember that sun damage to skin is cumulative. “Skin cancer has a lower incidence in people of colour, that much is true. However, skin cancers tend to be diagnosed later, with worse outcomes, in those population,” she adds.
I rarely go outdoors—I don’t need sun protection
If your idea of a fabulous time is curling up with a good book by the window, you’re getting more sun exposure than you think. Windows block UVB rays from burning your skin, but they do nothing to reduce UVAs, those tricky rays associated with melanoma. While it’s true you won’t get a sunburn while sitting indoors, UVA rays can filter through window glass, including skylights, and car windows.

I applied sunscreen this A.M., so I’m good
Putting on sunscreen before you leave home in the morning is a great start! However, “reapplication every two hours is key, especially after swimming, strenuous exercise, and sweating,” stresses Dr. Albright. That includes your SPF face makeup, too. Touch-ups during the day may be difficult to do, but if you’re counting on your makeup to protect your face from the sun, it’s an absolute must. And yes, there are sunscreens out there that you can apply over makeup.

Clothing provides plenty of sun protection
Not all fabrics are created equal. In fact, clothing made from lightweight summer fabrics typically have an ultraviolet protection factor (UPF) of around 5, which is too low to offer meaningful protection. “Most people think they’ll be protected if they wear a T-shirt, but those types of lightweight fabrics do not provide much sun protection,” says Dr. Albright. “If you will be in a situation of intense unshaded sun exposure, it’s a good idea to check out sun protective clothing. Protection levels range from UPF 15, all the way to 50+.” Here are seven more tips to protect your skin from sun damage.
You’re too old to get skin cancer
“Many of my patients think melanoma is a common cancer in young adults, especially women. They’re right, but that doesn’t mean elderly people, both men and women, don’t need to worry,” says Dr. Albright. According to the American Cancer Society, the risk of getting melanoma actually goes up as you age; the average age at diagnosis is 63. It’s important to continue to protect your skin from UV rays and to see a dermatologist regularly throughout your lifetime.
Few moles equals low skin cancer risk
The CDC lists having lots of moles as being a risk factor for skin cancer, but not having moles does not mean you’re risk-free. One study, reports the American Cancer Society, found that most people who are diagnosed with melanoma do not have many moles. The takeaway is simple: Keep an eye on any mole—even if it’s your only one—and let your doctor know if you notice a change.
People don’t die from skin cancer
Malignant melanoma is very deadly: According to data compiled by the American Cancer Society, over 91,000 people in the U.S. are expected to be diagnosed with new melanomas during 2018. Of that number, over 9,000 are expected to die from their disease. That’s really bad news. The good news is, most skin cancer can be avoided by dispelling the myths associated with it and following safe sun guidelines.
