The single most effective technique for removing basal cell carcinoma and squamous cell carcinoma, the most common types of skin cancer, is Mohs micrographic surgery. Mohs surgery accomplishes omitting cancer cells most completely while sparing the greatest amount of healthy tissue. Mohs surgery differs from other procedures in that microscopic examination of all removed tissues occurs during the procedure rather than after. This elimates the need to estimate how far or deep the roots of the skin cancer go.
Mohs surgery procedure
The procedure of Mohs surgery begins with removing one thin layer of tissue at a time. As the layers are removed, they are studied under a microscope for the presence of cancer cells on its margins. After seeing the margins under the microscope, if they are cancer-free, then the surgery is done. If there are still cancer cells on the margins, more tissues are removed from the margin where the cancer cells were found. This procedure is repeated until all of the margins of the final tissue sample have been examined and determined that it is cancer-free.
