A melanoma tumor is considered Stage I if it is up to 2 mm thick, and it may or may not have ulceration. There is no evidence the cancer has spread to lymph nodes or distant sites (metastasis).
Does melanoma always start on the skin?
Most melanoma cells still make melanin, so melanoma tumors are usually brown or black. But some melanomas do not make melanin and can appear pink, tan, or even white. Melanomas can develop anywhere on the skin, but they are more likely to start on the trunk (chest and back) in men and on the legs in women.
