Sun, sun, sun. The weather is one of the top reasons many of us live in Florida. But too much exposure to the sun's ultraviolet (UV) rays can cause skin cancer, the most common type of cancer. The American Cancer Society estimates that more than 5 million skin cancers are diagnosed each year in the United States. That's more than if you add up all cancers.

"Fortunately, there are many ways in which we can protect ourselves and minimize the risk," said Dr. Mercedes Florez-White, a dermatologist at FIU Health and associate professor of dermatology at the FIU Herbert Wertheim College of Medicine. "The problem is many people don't protect themselves."

A 2021 survey by the American Academy of Dermatology (AAD) found that a third of Americans lack a basic understanding of and sun protection.

"Something as simple as seeking shade whenever possible can go a long way toward preventing skin cancer," said Florez-White.

But the AAD survey found that more than half (53 percent) of adults are unaware that shade can protect them from the sun's harmful ultraviolet rays.

According to the AAD survey, "Gen Z (those born after 1996) appeared to have the biggest misunderstanding of the dangers of sun exposure and skin cancer, followed closely by Millennials (those born between 1981-1996)."
