Khloe Kardashian's facial tumor, Jesse Tyler Ferguson's skin cancer: What to know about SPF

Some of your favorite stars are sharing important reminders about skin health.

Khloe Kardashian took to her Instagram Stories Tuesday to clear up why she's been photographed with an "ever-evolving bandage" on her face the past few weeks.

"After noticing a small bump on my face and assuming it was something as minor as a zit, I decided to get it biopsied 7 months after realizing it was not budging," she wrote alongside a photo of the bump in question. 

A few days later, she was told she needed to have "an immediate operation to remove a tumor from my face."

Luckily, her doctor was able to get "everything," and she's now in the healing process.

She added she was sharing her story to remind her followers to "get checked, and frequently."

"Please take this seriously and do regular self-exams as well as your annual checkups," she urged fans.

Kardashian isn't the only one. Last August, Hugh Jackman shared a video of himself with a bandage on his nose, explaining his doctors saw something "irregular" and decided to do a biopsy.

"So if you see a shot of me with this on, don't freak out," the actor, 54, said before urging his followers to take care of their skin. "Remember, go and get a check and wear sunscreen. Don't be like me as a kid, just wear sunscreen."

He reiterated his message in the caption of the video: "Please get skin checks often, please don’t think it won’t happen to you and, above all, please wear sunscreen."

In a post to Instagram months earlier, "Modern Family" star Jesse Tyler Ferguson, 46, also urged his followers to make regular visits to see a dermatologist and wear sunscreen after getting "a bit of skin cancer" removed from his neck.

"Reminder to stay up to date on your dermatology checks… especially if you’re fair like me. I always wind up getting something taken from me, every time I go," he wrote. "Today, they took a bit of skin cancer that they found. Don’t worry, I got it early and I’m gonna be just fine. 🔪 (and, wear sunscreen! SPF 1000 for me!)

In the photo, you can see a bandage covering a section of his neck just below his ear.

His husband Justin Mikita wrote in the comment section, "Gotta keep you around forever. Derm appointments once a month!"

Experts also stress the importance of adequate SPF usage and proper application.

Dr. Barry D. Goldman, a clinical instructor at Cornell NewYork-Presbyterian Hospital, told USA TODAY in March that 80-90% of all skin cancers are on the face and neck.

"I've seen many tumors on the eyelids or around the eyes, the forehead. Basically, the whole face should be covered... We think of the whole face as a high-risk area for skin cancer," he said. 

Dr. Samer Jaber, also a dermatologist, tells his patients at Washington Square Dermatology to use sunscreen every day on the entire face.

"We know regular use of sunscreen on the face both prevents against skin cancer and is great for anti-aging, preventing wrinkles and discoloration on the face," he said, adding that it's also important to wear SPF on non-sunny days since UVA rays can penetrate clouds and windows.

Dr. Caroline Robinson, a dermatologist and founder of Tone Dermatology, added that it should be applied to any other uncovered areas as well, including the neck, ears and hands.

"The American Academy of Dermatology recommends applying 1 shot glass of sunscreen to cover the entire body, approximately 1/2 teaspoon of which will cover the face and neck. Your sunscreen should be at least an SPF 30, broad spectrum protecting against both UVA and UVB rays and water resistant," she added. "It should be worn daily regardless of whether you are indoors or outdoors and reapplied during the day especially if outdoors."

In addition to sunscreen, the American Academy of Dermatology Association suggests seeking shade when appropriate as well as wearing sun-protective clothing, including wide-brimmed hats, long sleeves and sunglasses.

The association also encourages patients to see a board-certified dermatologist if they notice new or suspicious spots on the skin, or anything changing, itching or bleeding.

In order to notice any changes, the association says it's beneficial to get in the habit of checking your skin monthly.
