Squamous cell carcinoma (SCC) is a common type of skin cancer that most often results from prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds or lamps. SCC are usually found on sun-exposed sites, such as the scalp, the backs of the hands or the ears. But squamous cell carcinoma of the skin can occur anywhere on the body, including inside the mouth, on the anus and genitals. The clinical presentation of a squamous cell carcinoma is usually a slow-growing, tender, scaly or crusted lump. The lesion may develop into a sore or ulcer that fails to heal. They often arise within actinic keratoses. A skin biopsy must be done to confirm the diagnosis. Squamous cell carcinoma of the skin is usually not life-threatening, though it can be aggressive in some cases. Untreated, squamous cell carcinoma of the skin can grow large or spread to other parts of your body, causing serious complications. The treatment for SCC depends upon its size, location, number to be treated and how far it has spread, and the overall health of the patient. Some of the treatments include: Electrodesiccation and curettage (ED&C), Surgical excision, Mohs surgery, topical treatments, photodynamic therapy, cryotherapy and Radiotherapy.
