Picture of Basal Cell Carcinoma
Basal cell carcinoma: The most common type of skin cancer, which commonly presents as a sore that seems to get better and then recurs and may start to bleed. Basal cell carcinoma often occurs on the face and neck, where the skin is exposed to sunlight. These tumors are locally invasive and tend to burrow in but not metastasize (spread) to distant locations.
