CBHA offers sun protection tips

MATTAWA - The warm days of summer are here, and the Columbia Health Association reminds you to protect against the sun and skin cancer.

According to the CBHA, skin cancer is the most common type of cancer in the United States. Ultraviolet (UV) rays from the sun are the main cause of skin cancer.

“UV rays are found primarily in sunlight and tanning beds,” CBHA Phyisician Assistant Melissa Alvarez said.

There are three types of UV radiation: UVA, UVB and UVC. UVA rays cause cells to age and can damage the DNA of skin cells.

UVB rays are the primary cause of sunburn. They are also thought to cause skin cancer as they can directly affect the cells’ DNA. UVC rays are unable to penetrate our atmosphere and are not normally thought to be linked to cancer.

UV rays can damage skin cells, including the gene that controls the growth of skin cells. This damage acts as the starting point for skin cancer.

Although UVB rays are thought to be the most potent cause of cancer, no UV rays are entirely harmful. The body needs small amounts of UV exposure to help produce vitamin D.

However, the amount needed is minimal and staying out in the noon sun without sun screen is more dangerous than beneficial.

“I can’t stress enough the importance of wearing sunscreen,” Alvarez said. “There are a lot of myths floating around out there. A common misconception is that only fair skinned people suffer the damage of UV rays.”

Alvarez said the risk of UV radiation on the eye and immune system is equal in fair and dark skinned people.

Alvarez recommends protective clothing. Hats that shade the ears, face, temples and back of the neck are recommended.

According to Alvarez, you should check yourselves frequently “head-to-toe” for signs of skin damage. Changes in the size, shape or color of moles are a warning sign. Watch for sores that bleed and don’t heal. Pay attention to red patches or lumps and changes in the sensation of a mole, such as itchiness or pain.

“Protecting your skin and eyes against the sun is one of the best things you can do to protect your future health,” Alvarez said.
