1. Electrodessication and curettage.

This method of treatment involves the application of an electric current of low voltage and high amperage. The heat produces cell death, and a spoon-shaped curette is then used to remove the dead tissue. This cauterization and curettage is performed sequentially until only normal tissue remains.

2. Cryotherapy.

This involves the application of an extremely cold material, such as liquid nitrogen ( — 196°C) or solid carbon dioxide (-79°C). Freezing of the tissue also produces cell death. Experience is required to assess the time needed to obtain sufficient depth of freezing to eradicate the tumour. Only superficial B.C.C.s, not nodular ones, are suitable for this form of treatment.

3. Surgery.

Sometimes excision and suturing, with or without skin grafting, may be necessary or preferable. However if the lesion is small, accessible and in certain specific regions, this is not normally required. It is the most suitable treatment, though, for recurrent tumours.

Other methods of treatment include Mobs Chemosurgery for difficult tumours, and radiotherapy for elderly people with tumours not overlying bone or cartilage and not exposed to wear and tear’.
