If you are particularly covered, the surgeon will assess each mole individually, determining which moles are suspicious and which are benign. The priority is to remove suspicious moles, those which are benign can be removed at a later stage.
There is a limit on how many moles can be removed in one session, and this is dependent on how many the surgeon can remove whilst the patient is under anaesthetic. The patient will be given a realistic view of how many growths can be removed in each session, and if more than one treatment is needed, patients can next come in a few days after their previous session.
