Micrographic (Mohs’) Surgery
This is a special surgical technique for removing certain types of skin cancer which allows us to map the excision margins microscopically.
As far as is possible, this means we know the cancer has been completely removed and because we are checking the entire margin it often means we conserve tissue which would have to have been removed if the tumour was excised with standard margins.
This is particularly valuable when treating sites which are functionally or aesthetically crucial such as around the eye. The procedure is done under local anaesthesia and after the tissue has been removed it is prepared and processed by a biomedical scientist before Dr Neil Walker examines the sections under a microscope. Further tissue is removed as necessary and the process continued until the margins are negative. The wound can then be repaired as appropriate.
