Excision is the removal of a skin cancer
along with some of the healthy skin tissue around it (margin). For this
local anesthetic is used to numb the area.
After the cancerous area is removed, the incision is closed with
stitches. If the incision is large, sometimes a skin
graft or flap is required. Reconstructive surgery may
be needed if the excision surgery creates a scar.
excision is different from
Mohs micrographic surgery. In Mohs surgery, the skin
cancer is removed one layer at a time. Each layer is checked under a microscope
right away. By doing Mohs surgery, the surgeon can cut away all the cancer
cells and spare as much healthy skin as possible.
Recovery from skin cancer surgery
varies depending on the site and how much skin is removed.
Standard excision works well to
basal cell and
squamous cell carcinomas. But Mohs surgery works
better for some skin cancer in places (such as the face) where it is important
to save as much skin as possible.
Standard excision treatment for
basal cell carcinoma less than
20 mm (0.8 in.) wide has cure
rates as high as 95 out of 100 people, when done with
4 mm (0.2 in.) margins.1 When standard excision is used to treat squamous cell carcinoma, about 92 out of 100 people are cured.
In most cases, Mohs micrographic surgery has cure rates that are a little
higher than excision cure rates.2
Risks of using excision to remove skin cancers
include the following:
The edges (margins) of the skin
where a skin cancer was removed will be examined in a lab by a pathologist to
see whether any cancer cells still remain outside the area of skin that was
removed. It is extremely important that the entire skin cancer be removed to
reduce the risk of recurrence.
