Doctors are good at telling which moles are probably normal and which look as if they might be atypical or unusual or even cancers. To tell if a mole is an early cancer, the doctor will usually need to look at some cells from the mole under a microscope.
Some specialist clinics eg at Addenbrooke's Dermatology have equipment that detects the most atypical suspicious moles without the need for biopsy. If a biopsy of a mole indicates the presence of atypical or already cancerous cells, removal of the mole will probably be recommended. The removal of the mole usually includes the removal of a normal margin of tissue around the mole.
This is to ensure that no cancer cells remain around the site of the mole. There are different techniques for mole removal according to where they are on your body. Those on the face are treated very carefully to minimise any scarring. Your doctor will carefully explain what is involved for you and support you throughout the process. Your general practitioner is the best person to advise you about the removal of moles within the NHS. For example, it might not be a health priority of the NHS for moles to be removed for purely cosmetic reasons. If the mole seems suspicious to them, it will be a priority to know if it is a skin cancer and they will advise you of how to proceed.
