Melanoma Symptoms & Diagnosis

Symptoms

Melanomas are not usually painful. At first they often have no symptoms. The first sign is often a change in the size, shape, color, or feel of an existing mole. They 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:

  • Uneven shape—one half does not match the shape of the other half
  • Ragged edges—ragged, notched, blurred, or irregular; pigment may spread into surrounding skin
  • Uneven color—color is uneven with shades of black, brown or tan, and possibly even white, gray, pink, red, or blue
  • Change in size—usually growing larger; usually larger than the eraser of a pencil (5 mm or ¼ inch)
  • Change in texture—may begin to have fine scales; may become hard or lumpy in advanced cases
  • Bleeding—may start to itch or, it may ooze or bleed in more advanced cases

Diagnosis

The doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor will look at your skin and moles. A biopsy will be taken of certain. Other moles will be watched over time.

The doctor may also examine lymph nodes. They may be in the groin, underarm, neck, or areas near the suspicious mole. Enlarged lymph nodes may suggest the spread of melanoma. The doctor may need to remove a sample of lymph node tissue to test for cancer cells.
