Mohs surgery is a procedure to treat superficial as well as more complex skin cancers where margins of surgical excision are critical. It is commonly used for skin cancers around the eyelids, nose and critical landmarks of the face. It is an excellent tool to clear margins for recurrent skin cancers or tumours with poorly defined margins.
Mohs surgery is performed under local anaesthesia in day surgery. The Mohs surgeon excises the tumour with a small margin. This specimen is then mapped, stained and examined under the microscope to serve as a guide to the exact location of the tumour and the clearance. If cancer cells are found in the margins, your surgeon will remove and examine another tissue sample taken from the specific region that is indicated on the map. These steps are repeated until the cancer is cleared.
Following skin cancer removal, wounds are reconstructed to preserve function and aesthetic appearance. In some cases, a plastic surgeon is required for reconstruction and this will be provided by the integrated skin cancer clinic.
