What is a potential indicator of malignant melanoma?

On the basis of multivariate analysis, the most important factors for predicting survival in patients with stage I and II melanomas are tumor thickness, presence of ulceration, and anatomic site of the primary tumor (the prognosis is poorer with head and neck lesions than with extremity lesions).

Where does melanoma usually spread to first?

Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade.

Where is malignant melanoma found in the body?

Melanoma can develop anywhere on the body, including the head and neck, the skin under the fingernails, the genitals, and even the soles of the feet or palms of the hands. Melanoma may not be colored like a mole. It may have no color or be slightly red, which is called amelanotic melanoma.

Is there a difference between melanoma and malignant melanoma?

Melanoma is a cancer that begins in the melanocytes. Other names for this cancer include malignant melanoma and cutaneous melanoma. Most melanoma cells still make melanin, so melanoma tumors are usually brown or black.
