EDISON - Dermatologists say many people forget to use sunscreen once summer ends, increasing their risk for skin cancer.

Skin cancer affects more than 2 million Americans each year and doctors say this time of year is particularly problematic.

Retired dermatologist Don Olshansky knows the dangers, and unfortunately has paid the price, getting skin cancer several times. "I used to tell my patients to wear the sunscreens until Halloween," he says.

Dr. Glenn Kolansky with the Advanced Dermatology Surgery and Laser Center in Tinton Falls says many people think they don't need sunscreen if the weather is cloudy. "I've had many people come into my office that are actually burnt because they say, 'I thought it was cloudy and I didn't need sunscreen,'" says Kolansky.

Doctors have several recommendations to reduce skin cancer risks. Everyone should avoid unprotected sun exposure, especially when the sun is high in the sky. Broad spectrum sunscreen, with both UVA and UVB coverage, should always be used, and it should be put on a half-hour before going outside.
