Stage 0: The cancer involves only the top layer of skin. It is carcinoma in situ. Stage I: The growth is 2 centimeters wide (three-quarters of an inch) or smaller. Stage II: The growth is larger than 2 centimeters wide (three-quarters of an inch). Stage III: The cancer has spread below the skin to cartilage, muscle, bone, or to nearby lymph nodes.
