Surgery for melanoma skin cancer
Surgery is the main treatment for most melanomas. It can often cure early-stage melanomas.
If melanoma was diagnosed with a skin biopsy, the area will probably need to be excised (removed) again to help make sure all of the cancer has been removed. This fairly minor surgery will cure most thin melanomas.
After the skin is numbed, more skin will be cut away from the area around the melanoma, and the wound is then stitched closed. This will leave a scar.
Mohs surgery: This method may be used in some cases to remove a smaller amount of tissue. In this approach the cancer is removed in very thin layers until a layer shows no signs of cancer. But not all doctors agree on the use of Mohs surgery for melanoma.
Amputation: If the melanoma is on a finger or toe and has grown deeply, the treatment may require that part or all of that digit be removed.
Lymph node dissection
In the past, a lymph node dissection was sometimes done to see if the melanoma had spread to nearby lymph nodes. Today, a sentinel lymph node biopsy (see “How is melanoma of the skin found?”) is often done first because it is a smaller surgery that is less likely to cause side effects such as lymphedema (see below).
If the sentinel lymph node biopsy (or another type of lymph node biopsy) finds cancer, then a lymph node dissection will likely be done to remove the other nodes in that area. It is not clear if a lymph node dissection can cure melanomas that have spread to the nodes. This is still being studied.
Removing lymph nodes can cause some long-term side effects, including lymphedema. Lymph nodes help drain fluid from the arms and legs. If they are removed, fluid can build up, leading to limb swelling. This side effect, along with the discomfort of the surgery itself, is the reason lymph nodes are not removed unless the doctor thinks it’s necessary. For more on lymphedema, see Understanding Lymphedema (for Cancers Other Than Breast Cancer).
Surgery for melanoma that has spread
When melanoma has spread from the skin to distant organs (such as the lungs or brain), it is very unlikely to be cured by surgery. Even so, surgery is sometimes done because removing even a few areas of spread could help some people to live longer or have a better quality of life. If you have metastatic melanoma and your doctor recommends surgery, be sure you understand what the goal of the surgery would be.
