The American Cancer Society publishes photos of melanoma skin cancer in its skin cancer gallery on its official website, Cancer.org, as of 2015. However, the ACS cautions that although the photos in the gallery are of actual cancers, skin cancer can take on a different appearance than the photos shown, so it is important that visitors see their doctors for any new or changing lumps, bumps, sores, marks or spots on their bodies.
Melanoma is one of the most dangerous forms of skin cancer, although it is less common than other skin cancer types, including squamous cell and basal cell cancers. Melanomas usually have multiple colors within their borders, with many appearing to be black or brown. Some can be tan, pink or white. They usually have jagged borders, are generally not symmetrical and they may not be round in shape.
Although melanomas can develop anywhere on the body, they are more apt to occur on the chest and back in male patients and on the legs in female patients. Other common areas for melanoma skin cancer include the face and neck. Melanomas tend to grow quickly, although this is not always the case, and they may even spread into neighboring skin, notes the ACS.
