The American Academy of Dermatologists wants to warn you about the danger of sun exposure. Skin cancer is the most common form of cancer in the United States. It is estimated one American dies every hour from melanoma, the deadliest form of skin cancer.

The AAD sets aside the first Monday of May as "Melanoma Monday," a day when dermatologists offer free skin cancer screenings. The free screenings have detected more than 188,000 suspicious lesions, including more than 21,500 suspected melanomas, since 1985.

This year the organization is encouraging everyone to make sure to check their skin for signs of cancer and to protect it for the sun's ultraviolet rays.

To reduce your risk of developing skin cancer, the CDC recommends:

Staying in the shade, especially during midday hours

Wearing clothing that covers your arms and legs

Wearing sunglasses that block both UVA and UVB rays

Using sunscreen with an SPF 15 or higher and both UVA and UVB protection

Avoiding indoor tanning
