squamous cell carcinoma

squamous cell carcinoma
(SCC)
the second commonest form of skin cancer (after basal cell carcinoma), occurring usually in late-middle and old age. Sunlight is the commonest cause but other environmental carcinogens may be responsible. SCC is mainly found on areas exposed to light and is three times more common in men than in women. SCC grows faster than basal cell carcinoma; it spreads locally at first but later may spread to sites distant from its origin (see metastasis). Treatment is usually by surgical excision or radiotherapy.
