#Melanoma Amelanotic melanoma is a type of #skin #cancer. Unlike most forms of melanoma, a person with amelanotic melanoma will develop a mole or similar growth that does not contain melanin. Melanin is the pigment that gives skin cells and moles their color. Because it does not have this pigment, amelanotic melanoma can be hard to detect. Amelanotic melanoma is a relatively uncommon form of cancer. A 2012 database study of people with melanoma found that just 3.9 percent had amelanotic melanoma. Nearly 70 percent of people with amelanotic melanomas had red skin lesions. In a larger-scale 2014 study, about 8 percent of people with melanoma had amelanotic growths. In itself, an amelanotic melanoma is no more dangerous than any other form of melanoma. Most people who are diagnosed and treated at an early stage survive. However, the fatality rates for amelanotic melanoma tend to be higher than for other types of melanoma. This is because amelanotic melanoma often goes undetected for longer, which gives it time to spread. A 2014 study found that 88 percent of people with amelanotic melanoma had survived 5 years following diagnosis, compared to 95 percent of people with pigmented melanoma.
