How is melanoma diagnosed?

The first step of diagnosing melanoma usually involves a visual inspection. If you notice an unusual growth or change in a mole on your own skin, see a doctor right away. The doctor will visually examine the mole or growth. If the doctor suspects melanoma, a biopsy will be performed, which involves removing the growth and analyzing it under a microscope. The method of biopsy depends on the size and shape of the growth. If it's a small mole or growth, the doctor will likely remove the whole growth for the biopsy. If the growth is larger, a doctor will usually remove only a part of the growth. If melanoma is confirmed, doctors will analyze the thickness and depth of the growth to determine the extent of the cancer.

A complete medical history, with special attention paid to family history of melanoma among immediate family members such as father, mother, brother, or sister, and a physical exam help your physician determine the level of risk that your signs or symptoms are melanoma. The only definitive way to diagnose melanoma is a biopsy of the abnormal area of the skin, which can be analyzed in the lab.
