This form of cancer begins in melanocytes, the cells that make the pigment melanin. It may begin in a mole, but can also begin in other pigmented tissues, such as in the eye or in the intestines.
A mole that:
- Changes in size, shape, or color
- Has irregular edges or borders
- Is more than one color
- Is asymmetrical (if the mole is divided in half, the 2 halves are different in size or shape)
- Oozes, bleeds or is ulcerated (a condition in which a hole forms in the skin when the top layer of cells breaks down and the tissue below shows through)
- A change in pigmented (colored) skin
- Is new or grows near an existing mole
Different treatments are available for patients with melanoma, including clinical trials of new treatments for patients with cancer.
