Micrographic (Moh's) Surgery

Micrographic (Moh's) Surgery 

In 1941, Frederick Moh's described a microscopically guided method of tracing and removing BCCs. The aim of surgery is to completely remove skin cancer by examining sections of tissue during surgery until adequate margins are achieved. It is a specialized procedure reserved for those tumours designated as being difficult, more aggressive, large, unusual, recurrent, previously incompletely removed or located at cosmetically sensitive or anatomically important sites.

This technique spares normal tissues because of the microscopic control involved. The pain, post-operative cosmetic result, follow up care, and healing time are similar as with standard surgical excision.

The overall chance of a cure with micrographic (Mohs) surgery is 95 - 99%.
