Specialist surgical care

Mohs & skin cancer surgery.

Mohs micrographic surgery is a specialised technique for selected skin cancers. Tissue margins are examined during the procedure, helping preserve healthy tissue. A specialist assessment is needed to determine whether Mohs is appropriate.

Skin cancer care

Assessment comes before the operation.

Skin cancer includes basal cell carcinoma, squamous cell carcinoma and melanoma. If you have a suspicious spot, a biopsy result or a confirmed diagnosis, specialist assessment helps determine the type of cancer and the most appropriate treatment pathway.

Treatment may involve a biopsy, standard excision, Mohs surgery or another approach. Mohs is most often considered for selected higher-risk basal cell and squamous cell carcinomas; it is not the right treatment for every skin cancer.

Understanding the procedure

Why Mohs may be recommended.

Mohs surgery may be considered for certain cancers in areas where preserving healthy tissue is particularly important, for tumours with less clearly defined edges, or for cancers that have returned.

It is not the right treatment for every skin cancer. Your dermatologist will consider the diagnosis, location, size, previous treatment and your individual circumstances before recommending an approach.
