Skin Cancer

Melanoma can occur anywhere on the body.

In men, melanoma is often found on the trunk (the area from the shoulders to the hips) or the head and neck. In women, melanoma often develops on the arms and legs. Melanoma usually occurs in adults, but it is sometimes found in children and adolescents.

Possible signs of melanoma include a change in the appearance of a mole or pigmented area. These and other symptoms may be caused by melanoma or by other conditions. A doctor should be consulted if any of the following problems occur:

A mole that:

  • changes in size, shape, or color.
  • has irregular edges or borders.
  • is more than 1 color.
  • is asymmetrical (if the mole is divided in half, the 2 halves are different in size or shape).
  • itches.
  • oozes, bleeds, or is ulcerated (a hole forms in the skin when the top layer of cells breaks down and the underlying tissue shows through).
  • Change in pigmented (colored) skin.
  • Satellite moles (new moles that grow near an existing mole).
