Squamous Cell Carcinoma (Skin Cancer)

Squamous cell carcinoma (SCC) is a type of skin cancer that begins in the squamous cells of the outer layer of skin. SCC is the second most common type of skin cancer, after basal cell carcinoma, and is often caused by exposure to the sun or other sources of ultraviolet (UV) radiation. Squamous cell carcinoma typically appears as a rough, scaly patch or bump on the skin that may be pink-to-red, white, or flesh-colored. It can also appear as an open sore that does not heal. If left untreated, SCC can grow into surrounding tissue and spread to other parts of the body, so it is important to have it diagnosed and treated by a dermatologist as soon as possible.

Treatment for SCC depends on the size, location, and depth of the cancer, but typically includes surgical excision or Mohs micrographic surgery. For early forms of SCC called squamous cell carcinoma in-situ, treatment by cryotherapy (freezing) or topical chemotherapy may be an option. In more extensive cases, radiation therapy or systemic chemotherapy may be necessary. It is important to protect your skin from the sun and avoid other sources of UV radiation, as well as to perform regular self-examinations and see a dermatologist for regular skin exams to help detect and prevent skin cancer.
