Mohs Micrographic Surgery for Nonmelanoma Skin Cancer
Mohs micrographic surgery involves removing a
skin cancer one layer at a time and examining these layers under a microscope
immediately after they are removed. This procedure allows for a close
examination of each layer of skin to detect cancer cells. It also allows a
minimal amount of tissue to be removed while making sure that all
the cancer cells are removed.
local anesthetic is injected into the skin before the
surgery. Your doctor then begins to remove the skin cancer and a small amount
of healthy tissue, one layer of skin at a time. Each tissue layer is prepared
and examined under the microscope for cancer cells. Surgery is complete when no
more cancer cells are detected.
Clinical validity refers to the predictive value of a test for a given clinical outcome (e.g., the likelihood that cancer will develop in someone with a positive test). It is primarily determined by the sensitivity and specificity with which a test identifies people with a defined clinical condition within a given population. Sensitivity of a test refers to the proportion of people who test positive for a clinical condition among those who actually have the clinical condition; specificity refers...
Mohs micrographic surgery can be an
effective treatment for skin cancer. This technique preserves as much nearby
healthy skin as possible. It is recommended for squamous cell carcinoma when the highest cure rate is desired while sparing as much healthy tissue as possible.1 And for basal cell carcinoma, Mohs surgery is the best treatment for sparing healthy tissue and preventing recurrence.2
Risks of surgery include:

What To Think About
Mohs micrographic surgery is the
best procedure to preserve skin tissue surrounding the cancer. But it requires
special training and equipment. And it is time-consuming and expensive.
