The most common way to treat a melanoma is to have it surgically removed together with some of the surrounding healthy tissue and then tested to see if it is cancerous. This is usually performed under local anaesthetic, although general anaesthetic (which means you will be asleep) is sometimes needed. Radiotherapy (a form of radiation) is also used to treat some forms of skin cancer, to reduce the chance of it coming back after surgery. There are several different types of treatment for skin cancer. The one you have will depend on various factors, including the type of cancer and how far it has spread. Surgery to remove the affected skin is often the first option. Your doctor will discuss the best type of treatment for you depending on the type of skin cancer you have.
