Images of melanoma are found online at various websites, including WebMD, Mayo Clinic, Healthline, American Cancer Society and MedlinePlus. Melanoma is an aggressive form of skin cancer, and it causes the most deaths due to skin cancer, according to MedlinePlus.
Online sources present images of melanoma, other types of skin cancers and benign skin growths so that the visitor can perceive contrasts between the various types of skin cancers and contrasts between cancer and harmless growths. Skin cancer image collections often emphasize five specific, key factors to look for in identifying a skin growth as cancerous or harmless. These factors are the ABCDE of skin cancer: asymmetry, borders, colors, diameter and evolution, according to MedlinePlus.
