The most common types of skin cancer include basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM). Both BCC and SCC are known as non-melanoma skin cancer (NMSC).
Basal Cell Carcinoma (BCC) is the most common but least dangerous form of skin cancer. It grows slowly, invades locally, and rarely spreads throughout the body.
Squamous Cell Carcinoma (SCC) occurs in areas of high sun exposure (head, neck, arms and hands) and grows more rapidly than BCCs. Because SCC can spread around the body, it can be life-threatening if not caught and treated early.
Malignant Melanoma (MM) accounts for 5% of all skin cancers and may develop from a mole or as a new skin lesion. Melanoma can occur in any part of the body, even in non-sun-exposed areas. Because it has a tendency to spread through the lymphatics or bloodstream, melanoma can be life-threatening if not caught and treated early.
