Skin cancer is on the rise among young peopleWilliam Perugini/Shutterstock
Melanoma, the potentially fatal form of skin cancer
increased eightfold for women under 40 and fourfold among young men since 1970, according to research
out of the Mayo Clinic in Rochester, Minnesota. The researchers suggest that tanning along with better detection may be driving the uptick. What's more, melanoma in children, while still extremely rare, increased about two percent per year
from 1973 to 2009 among U.S. children from newborns to age 19. And it's not just melanoma either, says Andrew C. Krakowski, MD, the Chief Medical Officer at DermOne
, LLC in Conshohocken, Pennsylvania. "I took care of two five-year olds with a syndrome that caused them to make basal cell skin cancers—about 500 of them each!" Find out what skin cancer looks like
You can get skin cancer in your eyes triocean/Shutterstock
Ocular or eye melanoma can present as a freckle inside the eye, says San Diego, Calif.-based dermatologist Mona Z Mofid, MD
, also the medical director of the American Melanoma Foundation. There are around 2,000 new cases of eye melanoma diagnosed each year in the United States, according to the Melanoma Research Foundation
. "The eyelid area is also a common site for other types of skin cancer such as basal cell and squamous cell and these often go unnoticed," Dr. Mofid says.
Skin cancer can develop where the sun doesn't shineplenoy m/Shutterstock
Places like the underside of the penis, inside the vagina, and in the crease of the buttocks can and do develop skin cancers, says New York City dermatologist and Mohs surgeon Michelle Henry, MD
, also a Clinical Instructor of Dermatology at Weill Cornell Medical College. And if you have ever wondered why your dermatologists spreads your toes during your annual skin cancer check, it's because, yes, melanoma can turn up there, as well, adds New York City dermatologist Dendy E. Engelman, MD
. "I have diagnosed Invasive melanoma between the toes of a 64-year-old lady," she says.
"I found a pigmented basal cell carcinoma in a 50-year-old Hispanic woman's arm pit which looked just like a skin tag, but the clincher was that it kept growing and would bleed time and again," says Adam Friedman, MD
, an Associate Professor of Dermatology at George Washington School of Medicine and Hospital in Washington DC. "This is why it is so important to have yearly skin checks so that a trained professional can look at every nook and cranny where one can't or would not even want to look," he says.
Darker skin is not magically protected from skin cancerSata Production/Shutterstock
People with darker skin types may be less likely to develop skin cancer, but when they do, it is often more advanced by the time it's caught and therefore more difficult to treat. The estimated five-year melanoma survival rate for African Americans is 69 percent, compared to 93 percent for whites, the Skin Cancer Foundation
states. Think about Bob Marley, says Mofid. The reggae singer died from melanoma on his toe. "Darker-skinned individuals underestimate their skin cancer risk and the highest increase in skin cancer has been among the Hispanic population," she says. "Monthly self exams (including between the toes) as well as regular skin checks by your dermatologist can help with early detection." Here's how to check yourself for skin cancer
Moles aren't the only sign of skin cancerwavebreakmedia/Shutterstock
Irregular, growing moles are the most common sign of skin cancer, and the "ABCDE rule" serves as a good guide for identifying melanoma.
- Asymmetry: The mole is misshapen.
- Border: The edges are irregular.
- Color: The color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue.
- Diameter: The spot is larger than a pencil eraser.
- Evolving: The mole is changing in size, shape, or color.
But melanomas may also look like a sore or pimple that doesn't heal. They may itch, ooze, bleed or hurt, the American Cancer Society points out
. These same skin cancer symptoms may also be signs of basal or squamous cell skin cancers.
There is no good type of skin cancerSERGEI PRIMAKOV/Shutterstock
Melanoma is the deadliest form of skin cancer, which is why some people refer to the other types of skin cancer (basal cell or squamous cell) as the "good kind." There is no good type of skin cancer. Untreated squamous cell skin cancers, in particular, can grow large, cause discomfort and can spread. Basal cell carcinomas can also cause disfigurement if not treated early, according to experts at the Skin Cancer Foundation
The sun's UV rays aren't the only cause of skin cancerLucky Business/Shutterstock
Yes, exposure to the sun's ultraviolet rays is the main cause of skin cancer—and indoor tanning booth sessions increase risk as well—but your genetics play a role. If someone in your family has battled skin cancer, you could be at increased risk. Another risk factor is if you've ever had to take immunosuppressant drugs after organ transplantation (the meds suppress immunity). There are other surprising skin cancer causes
We still don't use enough sunscreen!fizkes/Shutterstock
Despite all of the public health messages about the sun and skin cancer risk, most of us apply just 25 to 50 percent of the recommended amount of sunscreen, according to the American Academy of Dermatology. See more here
. Here's the deal: One ounce (a shot glass) is what's needed to cover all your exposed skin, and it should be applied to dry skin 15 minutes before stepping outside. Then you have to reapply every two hours, or after swimming or sweating. Choose a broad spectrum sunscreen—which means it blocks both UVA and UVB rays—with an SPF of at least 30. Importantly, use sunscreen all year round—not just when you hit the beach. Here are some of the other sunscreen mistakes
