Surgery is the most common treatment for skin cancer. How it’s done depends mostly on the size of the cancer and where it is. Small cancers can often be removed by cutting them out (excision) under local anaesthetic or by a technique known as curettage and electrocautery.
Larger tumours are more likely to be cut out while you are under a general anaesthetic, and the skin 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.
