(Basal Cell Carcinoma; Squamous Cell Carcinoma)
- Basal cell carcinoma —This is the most common type of skin cancer. Basal cell carcinoma develops in the outermost layer of skin. This cancer usually grows slowly and does not spread to other tissues in the body.
- Squamous cell carcinoma —This cancer develops in the uppermost layer of skin cells. Squamous cell carcinoma usually grows slowly. However, in some cases it can grow fast and spread to other tissues in the body. If treated early this type of cancer is rarely fatal. However, the cancer can be fatal if it spreads beyond the skin.
