Skin Cancer Stages
Skin cancer occurs when DNA molecules become irreparably damaged, leading to uncontrollable cell growth and division that causes a tumor or tumors to form. After diagnosis, doctors must pinpoint the stage of the cancer using a variety of diagnostic tools and measurement systems. This is called "staging," and helps doctors determine the proper treatment course.
