Chemotherapy uses anti-cancer drugs to destroy cancer cells. Chemotherapy cream or lotion can be applied directly onto the skin cancer. This is called topical chemotherapy.
Usually a drug called 5-fluorouracil (Efudix®), often called 5FU, is used to treat non-melanoma skin cancers. Your doctor or nurse will give you the cream to put on at home. Your doctor, nurse, or a pharmacist, will explain how to apply it.
You apply the cream either once or twice a day. The area can usually be left uncovered. However, your doctor or nurse may advise you to cover the area with a waterproof dressing after putting on the cream. You should follow the instructions they give you.
The treatment should make the skin red and inflamed. Once the area becomes sore and weepy, the treatment will be stopped. This is usually after 3 to 4 weeks, depending on where it is on your body. It may be less if it is on your face, or longer for other areas.
If the area is very sore, your doctor can prescribe a steroid cream to help.
The skin usually takes 1 or 2 weeks to heal after you finish the treatment. But sometimes it can take longer.
Try to protect the treated area from the sun, as it can make the inflammation worse. Usually there are no other side effects with this type of chemotherapy.
