Skin consists of three different types of cells, and squamous cell and basal cells and melanocytes. Squamous cells located just beneath the surface of the skin with the basal cells and melanocytes from beneath them under the basal cells. Depending on the skin cells that are affected by cancer, will determine the type of cancer is and treatment.
