(Cutaneous Melanoma; Malignant Melanoma)
by Laurie LaRusso, MS, ELS
Melanoma is a type of skin cancer. It is the least common form of skin cancer. It is also one of the more serious forms because it is more likely to spread to other parts of the body.
Melanoma arises from the type of cell called melanocytes. They give moles their dark colors. These cells can be found in the skin, eyes, digestive system, nail beds, or lymph nodes. Although melanoma is most common in the skin, it may also arise in these other areas.
Treatment for melanoma depends on how early it is detected, or if the melanoma has spread.
Cancer occurs when cells in the body divide without control or order. Eventually these uncontrolled cells form a growth or tumor. The term cancer refers to malignant growths. These growths invade nearby tissues and spread to other parts of the body. It is not clear exactly what causes these problems in the cells. It is probably a combination of genetics and environment.
Risk Factors TOP
The most common risk factor is exposure to ultraviolet (UV) radiation. The most common source of UV comes from the sun, but it is also found in sun lamps and tanning booths.
Melanoma is found most often in older adults, but it can happen in young adults. It is more common in people who are Caucasian. Other factors that may increase your chances of melanoma include:
Melanomas are not usually painful. They often have no symptoms at first.
The first sign is often a change in the size, shape, color, or feel of an existing mole. Melanoma may also appear as a new, dark, discolored, or abnormal mole. Remember that most people have moles. Almost all moles are benign.
The following are signs that a mole may be a melanoma (ABCDE criteria):
Early diagnosis and treatment is important. Take the following steps to find melanoma in its early stages:
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your doctor will look at your skin and moles. A skin biopsy of the suspicious area will be done. A tissue sample will be examined for cancer cells.
Your doctor may also examine lymph nodes. Enlarged lymph nodes may suggest the spread of melanoma. A sample of lymph node tissue may also be removed for testing.
Once melanoma is found, more tests will be done to determine the stage of cancer. Melanoma is staged like other cancers, from I to IV. The stage will help determine your treatment course.
Treatment will depend on the location and stage of the melanoma. Talk to your doctor about the best treatment plan for you. Treatment options may include one or more of the following:
Lymph nodes near the tumor may also be removed for testing or to stop the spread of cancer.
Chemotherapy is medication that kills cancer cells. It is used to treat advanced melanoma. There are many options. Choices will be made based on your specific needs.
Other Medications TOP
Immunotherapy is used to treat advanced melanoma, and melanoma that has a high risk of returning. It makes the body's own immune system better at finding and destroying cancer cells.
Some people have a mutation in the BRAF gene. This can make the melanoma grow and divide quickly. BRAF mutation is present in nearly half of all melanomas. Certain medications can help your body target cells with the BRAF mutation.
Radiation Therapy TOP
Radiation can kill cancer cells and shrink tumors. It is usually used in combination with other therapies. It may be the sole treatment for eye melanomas.
