BASAL CELL CARCINOMA

Written by

The most common form of skin cancer. Its main cause is cumulative exposure to ultraviolet light; most tumours develop on exposed sites, chiefly the face and neck. It grows very slowly, often enlarging with a raised, pearly edge, and the centre may ulcerate (rodent ulcer). It does not metastasise (see METASTASIS) and can be cured by surgical excision or RADIOTHERAPY. Small lesions can also be successfuly treated by curettage and cauterisation (see ELECTROCAUTERY), LASER treatment or CRYOSURGERY. If the diagnosis is uncertain, a biopsy and histological examination should be done.
