Surgery is the most common treatment for skin cancer. How it is done depends mostly on the size of the cancer and where it is.
If you have a small cancer, the doctor can usually remove (excise) it under local anaesthetic. Or they may use a technique to destroy the cells known as curettage and electrocautery.
A larger cancer is more likely to be removed while you are under a general anaesthetic. The skin is replaced with a skin graft or skin flap, if needed. A type of surgery called Mohs micrographic surgery (or margin-controlled excision) is used in some hospitals in the UK.
