Basal cell carcinoma (BCC) is a type of skin cancer that results from the uncontrolled growth of basal cells, which are found in the lower layer of the epidermis. BCC is the most common type of skin cancer, accounting for approximately 75-80% of all skin cancer cases. It is caused by prolonged exposure to ultraviolet radiation from the sun, as well as tanning beds. BCC typically appears as a small, fleshy bump or nodule on the skin, and can range in color from tan to pink to red. It may also appear as a flat, scaly area of skin. BCC can be highly invasive and spread to other parts of the body if left untreated. Early diagnosis is key, as BCC is highly treatable when caught early. Treatment options include topical creams, cryotherapy, radiation therapy, and surgical excision. The outlook for BCC is good when it is identified and treated early. If left untreated, however, it can cause significant damage to the skin, including scarring and disfigurement.
