About skin cancer

Skin cancer is a disease of the body's skin cells. Skin cancer develops when the cells which make up our skin are damaged and grow abnormally.

The sun's ultraviolet (UV) radiation is the main cause of skin cancer. Each time your skin is damaged by UV, changes take place in the structure and function of our skin cells. If UV damage keeps adding up, skin cells become less able to repair, increasing the risk of skin cancer.

Using sun protection during sun protection times will prevent UV damage and cut your cancer risk – and it's never too late. Using sun protection will cut your risk of skin cancer at any age.
