Skin cancer is a disease of the body's skin cells usually as a result of skin cell damage. Skin cancer can grow when the cells which make up our skin are damaged, causing them to grow abnormally.
Each time your skin is exposed to ultraviolet (UV) radiation, changes take place in the structure and function of our skin cells. Over time, the skin can become permanently damaged, which will worsen with each exposure.
Every additional decade of overexposure to UV further increases your risk of skin cancer. Increased use of sun protection against sun exposure will help prevent skin cancer and melanoma at any age.
All skin types can be damaged by exposure to UV radiation. People with skin types which are less likely to burn are still at risk, albeit lower, of developing skin cancer.
