Basal cell carcinoma. Close-up of a skin tumour on the cheek of an elderly man. This cancer is known as basal cell carcinoma,or rodent ulcer. It commonly occurs on the face or neck region,typically affecting fair-skinned people over age 50. Direct skin damage from ultraviolet radiation in sunlight is thought to be the cause in most cases. Basal cell carcinoma usually appears as a small,flat nodule growing slowly,which then breaks down at the centre to form a shallow ulcer. The tumour may invade deeper tissues if untreated. It may be removed by cryosurgery or radiotherapy or with a surgical operation. Treatment usually results in a complete cure | |
