Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Local growth mostly: Mostly skin cancers (like all cancers) grow locally, spreading both side to side as well as down. For melanomas in particular, deep growth is more dangerous. Cancers also can jump (or metastasize) via lymphatic vessels or blood vessels.

Darker is protective: Skin cancer is 20 times more likely in whites versus black skin. The darker the inherent color of the skin the less likely to get skin cancer.

What is Cancer?: Cancer is the uncontrolled growth of a part of the body, with the potential for spread locally or to distant locations, causing dysfunction or organ failure and, ultimately, death. Any cancer increases the risk for blood clots, which can flow to the lungs and kill a patient (pulmonary embolism). Cancers tend to deprive a patient of nutrients, damaging the immune system, increasing infection risk. ...Read moreSee 1 more doctor answer
