How does polypoid melanoma affect the body?

The cause of polypoid melanoma is thought to be tied to the overproduction of certain skin cells called melanocytes, which are the cells that produce skin pigment. This cell overproduction usually leads to a new skin growth that appears out of nowhere. Generally, these growths are found on the torso, though they can form anywhere on the body, including mucous membranes. Polypoid melanoma lesions are usually very thick, dome-shaped, and may be a variety of colors ranging from black to completely colorless. Polypoid melanoma progresses very quickly, and if it's not diagnosed very early, the cancer can spread rapidly through the skin to other parts of the body.
