Cedars-Sinai Dermatologist: How to Prevent Skin Cancer, Post-Pandemic
Memorial Day weekend is here, traditionally the time to bust out the pool-and-beach gear, fire up the barbecue and swap sweatshirts for shorts, T-shirts and sandals.
This year, as sun and sports enthusiasts—and just about everyone else—emerge from their pandemic cocoons, it’s important to take extra precautions against sun overexposure, dermatologists say.
“People who have been spending a prolonged time indoors are at increased risk of sunburns and sun damage, including skin cancer later on,” said Cedars-Sinai dermatologist Brandon E. Cohen, MD. “That is particularly true in the current circumstance, given that many people have been indoors longer than usual.”
Skin cancer is the abnormal growth of skin cells, which usually is caused by the sun’s harmful ultraviolet rays and ultraviolet tanning beds. More people are diagnosed with skin cancer than all other cancers combined, Cohen said.
The three major types of skin cancer are:
- Basal cell carcinoma, the most common type of skin cancer, with 3.6 million cases diagnosed yearly in the U.S.
- Squamous cell carcinoma, the second most common type, with 1.8 million annual U.S. cases
- Melanoma, the most dangerous type of skin cancer, with more than 200,000 new U.S. cases and about 7,200 deaths projected this year
Although most skin cancers are successfully treated, experiencing five or more blistering sunburns between ages 15 and 20 increases melanoma risk by 80% and nonmelanoma skin cancer risk by 68%, according to the American Academy of Dermatologists.
“Melanoma is the most concerning skin cancer,” Cohen said. “It arises out of the cells that make up moles. Some clues that you have melanoma may be a pigmented mole that can be asymmetric in shape, variable in its colors, or if it’s a new mole or one that’s been changing or growing over time.”
Cohen recommends these seven tips to prevent skin cancer:
- Slowly increase your sun exposure. A trip to the ballpark or a long walk or run for your first dose of sun this season can cause a serious sunburn and lasting damage.
- Apply a sunscreen that has broad-spectrum protection and an SPF of at least 30. Remember to reapply it every few hours when outdoors. Use sunscreen even for short walks and car trips.
- Wear sun-protective clothing, such as hats and long sleeves.
- Avoid direct sun exposure during peak times—between 10 a.m. and 2 p.m.
- Do not get a sunburn.
- Avoid all tanning bed exposure.
- Perform regular skin checks on yourself, your children and partners to look for new or unusual-looking moles.
“Avoid skin cancer if you can, but if you are diagnosed, the good news is that the vast majority of those cancers can be successfully treated,” Cohen said. “There also have been a number of exciting innovations in the field of medicine and oncology that greatly improve the outcomes of melanoma patients. Treatments such as immunotherapies help boost the patient’s own immune system to fight the cancer.”
