Images of melanoma cancer are presented on the official websites of the National Cancer Institute at the National Institutes of Health and Mayo Clinic. An image gallery of various types of skin cancer, including melanoma cancer, is also provided by the American Cancer Society.
Melanoma is a malignant tumor that forms due to a mutation in a person's melanocytes, which are responsible for producing the pigment melanin. They generally form in the torso region in men and the lower limbs in women, as stated by the American Cancer Society.
The only method of determining melanoma cancer is by performing a biopsy, according to the National Cancer Institute. The photos it provides include an abnormally large, irregularly shaped melanoma with varying color tones and uneven borders. The slide show of melanoma pictures presented on Mayo Clinic serves as a guide for various identifying factors that may indicate melanoma.
