• Asymmetry of one side versus the other:

Most early melanomas are asymmetrical meaning a line through the middle would not create matching halves.

• Border Shape:

The borders of early melanomas are often uneven and may have scalloped or notched edges.

• Color Variation:

Common moles are usually a single shade of brown. Varied shades of brown, tan, or black are often the first sign of melanoma. As melanomas progress, the colors red, white, and blue may appear.

• Diameter/Size:

Early melanomas tend to grow larger than common moles (at least to the size of a pencil eraser).

• Evolving:

Any changes in size, shape, color, or elevation can be a sign of danger. Example: When a mole starts to evolve or change, see a doctor.

Melanoma can only be treated with surgery or radiation therapy. Mohs surgery, the most advanced technique of treating cancer would be ineffective on Melanoma patients. Since Mohs surgery involves removing only cancerous cells, it is not recommended for Melanoma patients.
