If you would like to know more about melanoma, the National Library of Medicine and the National Institutes of Health have a website called Medline.

Here's some pretty neat information for you regarding melanoma. Melanoma is a malignant tumor that originates in melanocytes, the cells which produce the pigment melanin that colors our skin, hair, and eyes and is heavily concentrated in most moles. The majority of melanomas, therefore, are black or brown. However, melanomas occasionally stop producing pigment. When that happens, the melanomas may no longer be dark, but are skin-colored, pink, red, or purple.
Malignant melanomas are usually small brown-black or larger multicolored patches, plaques or nodules with irregular outline. They may crust on the surface or bleed. Many of them may arise in pre-existing moles.

I should point out that a growing or bleeding mole is not necessarily a sign of melanoma. I had a growing and occasionally bleeding mole on my upper lip removed in 1982 which upon biopsy turned out to be non-malignant. However, any change in a mole should be checked out to be sure.
