Non-melanoma skin cancer (NMCS) refers to a group of cancers that slowly develop in the upper layers of the skin. The term non-melanoma distinguishes these more common types of skin cancer from the less common skin cancer known as melanoma, which can be more serious. Overexposure to ultraviolet (UV) light is the main cause of non-melanoma skin cancer. UV light comes from the sun, as well as from artificial tanning sunbeds and sunlamps.
Surgery is the main treatment for non-melanoma skin cancer. It involves removing the cancerous tumor and some of the surrounding skin. Other treatments for non-melanoma skin cancer include freezing (cryotherapy), anti-cancer creams, radiotherapy, Rhenium-SCT, and other techniques.
