Surgery Overview

Surgery to remove (excise) a melanoma removes the entire melanoma along with a border (margin) of normal-appearing skin. The width of the border of normal skin removed depends on the depth of the melanoma. More tissue, usually skin and fat, is also removed from under the melanoma.

• Small excisions may be closed with stitches and heal without problems.
• Large excisions or those located on the hands, face, or feet may require a skin graft to close the wound after surgery.

The type of anesthetic used for your surgery depends on the size and location of the melanoma. Surgery on small, easily reached melanomas may require only a local anesthetic. Surgery for larger melanomas may require general anesthesia.

How It Is Done

Surgery to remove (excise) melanoma removes the cancer and a border of healthy tissue. In the "Area of excision" picture:

• The inner circle represents the melanoma and healthy tissue that are excised.
• An eye-shaped incision (cut) is often done so that the surgical site can be neatly closed.

If the excision is small, the skin may be closed with stitches after surgery. The "After surgery" picture shows the usual shape of the scar after surgery to remove a small melanoma.

If the excision is large, a skin graft may be needed.

Other ways of removing a melanoma can leave a round scar or a scar shaped a little like the letter "Z."

What To Expect

Recovery after surgery to remove a melanoma depends upon the site and extent of surgery. The wound may take longer to heal if reconstructive surgery techniques such as skin grafts are used.

Why It Is Done

Surgery is the most common treatment for melanoma. Sometimes lymph nodes may be removed at the same time to check them for cancer. Surgery also may be done to remove lymph nodes that have cancer or to remove tumours that may have spread to other parts of the body.

How Well It Works

Surgery to remove the melanoma usually cures melanoma if it is found early. Surgery and other treatments may be needed if cancer is found in the nearby lymph nodes.

Surgery may be used as part of the treatment for metastatic melanoma. In certain cases, surgery can help with long-term survival. And surgery may help relieve symptoms.

Risks

Risks of surgery to remove melanoma include:

• Infection.
• Scarring.
• Bleeding.
• Rejection of the skin graft.
