Skin cancer is a disease in which cancer (malignant) cells are found in the outer layers of your skin. Your skin protects your body against heat, light, infection, and injury. It also stores water, fat and vitamin D.

The skin has two main layers and several kinds of cells. The top layer of skin is called the epidermis. It contains three kinds of cells: flat, scaly cells on the surface called squamous cells; round cells called basal cells; and cells called melanocytes, which give your skin its color.

On this site we provide information on melanoma, basal cell, squamous cell and AK pre-cancers as well as ways to prevent sun damage. This information is not meant in place of a visit to a board-certified dermatologist, but as a supplement to regular screenings.
