General Information About Skin Cancer
Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin. The skin is the body's largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D. The skin has several layers, but the two main layers are the epidermis (upper or outer layer) and the dermis (lower or inner layer).

- Fluorouracil (5-FU). With topical chemotherapy, the medicine that kills cancer cells is in a cream or lotion that is put right on the skin. Treatment with 5-FU cream or lotion is used for both basal cell and squamous cell carcinomas that are superficial (only in the top layer of skin).
- Imiquimod 5% cream (Aldara). Imiquimod is used to treat superficial basal cell cancer on the skin of the body, neck, arms, or legs, but it is not approved for treating the face.
People treated with medicines will need to have regular follow-up visits with their doctors to make sure the skin cancer is gone.
Chemotherapy may be used to destroy cancer cells in the small number of people who have basal cell or squamous cell carcinoma that has spread (metastasized) to other organs in the body, though metastasis is rare.
What To Think About
Medicines such as 5-FU and imiquimod may cause your skin to be sore. Your skin may turn red, swell, itch, or break out in a rash. Your skin may also be sensitive to sunlight. If your skin turns too red or raw, your doctor may stop the treatment.
How well medicines work for nonmelanoma skin cancer is not fully known. Studies are currently being done on the following medicines to find out their effectiveness.
- Interferon is a substance produced by the body that helps the immune system fight disease more effectively.
- Tretinoin (Retin-A) cream is derived from vitamin A and is one of a class of substances called retinoids. Tretinoin cream may prevent new skin cancers in people who have an increased risk for skin cancer.
