What are the side effects of treatment for melanoma?
Because treatment may damage healthy cells and tissues, unwanted side effects sometimes occur. These side effects depend on many factors, including the location of the tumor and the type and extent of the treatment. Side effects may not be the same for each person, and they may even change from one treatment session to the next. Before treatment starts, the health care team will explain possible side effects and suggest ways to help the patient manage them.
The side effects of surgery depend mainly on the size and location of the tumor and the extent of the operation. Although patients may have some pain during the first few days after surgery, this pain can be controlled with medicine. People should feel free to discuss pain relief with the doctor or nurse. It is also common for patients to feel tired or weak for a while. The length of time it takes to recover from an operation varies for each patient.
Scarring may also be a concern for some patients. To avoid causing large scars, doctors remove as little tissue as they can (while still protecting against recurrence). In general, the scar from surgery to remove an early stage melanoma is a small line (often 1 to 2 inches long), and it fades with time. How noticeable the scar is depends on where the melanoma was, how well the person heals, and whether the person develops raised scars called keloids. When a tumor is large and thick, the doctor must remove more surrounding skin and other tissue (including muscle). Although skin grafts reduce scarring caused by the removal of large growths, these scars will still be quite noticeable.
Surgery to remove the lymph nodes from the underarm or groin may damage the lymphatic system and slow the flow of lymphatic fluid in the arm or leg. Lymphatic fluid may build up in a limb and cause swelling (lymphedema). The doctor or nurse can suggest exercises or other ways to reduce swelling if it becomes a problem. Also, it is harder for the body to fight infection in a limb after nearby lymph nodes have been removed, so the patient will need to protect the arm or leg from cuts, scratches, bruises, insect bites, or burns that may lead to infection. If an infection does develop, the patient should see the doctor right away.
The side effects of chemotherapy depend mainly on the specific drugs and the dose. In general, anticancer drugs affect cells that divide rapidly, especially:
The side effects of biological therapy vary with the type of treatment. These treatments may cause flu-like symptoms, such as chills, fever, muscle aches, weakness, loss of appetite, nausea, vomiting, and diarrhea. Patients may also get a skin rash. These problems can be severe, but they go away after treatment stops.
The side effects of radiation therapy depend on the amount of radiation given and the area being treated. Side effects that may occur in the treated area include red or dry skin and hair loss. Radiation therapy also may cause fatigue. Although the side effects of radiation therapy can be unpleasant, the doctor can usually treat or control them. It also helps to know that, in most cases, side effects are not permanent.
People with melanoma may not feel like eating, especially if they are uncomfortable or tired. Also, the side effects of treatment, such as poor appetite, nausea, or vomiting, can be a problem. Foods may taste different. Nevertheless, patients should try to eat well during cancer therapy. They need enough calories to maintain a good weight and protein to keep up strength. Good nutrition often helps people with cancer feel better and have more energy.
The doctor, dietitian, or other health care provider can suggest ways to maintain a healthy diet.
