Mohs micrographic surgery
Mohs surgery is a technique of removal of cancerous skin lesions that ensures that the entirety of the lesion is fully removed before the skin is closed. It also allows the surgeon to perform the smallest, most precise and efficient excision possible.
This technique consists of removing the lesion piece by piece and immediately analysing each of them with a microscope. This allows the surgeon to know exactly when the healthy tissue is reached and when to stop the excision.
This technique was pioneered by Dr. Frederic Mohs in the 1940s and quickly spread throughout the US, although it was a bit less popular in Switzerland and France. It is especially effective because, if the lesion is not removed entirely, it can resurge relatively quickly while remaining hidden by the skin used to close the opening from the initial removal. This could cause the development of a tumor that would require a more serious and invasive operation.
Mohs surgery is especially effective for cancerous lesions located on the face.
