Melanoma is an extremely virulent, life-threatening cancer. It is readily detectable and always curable if treated early, but it progresses faster than other types of skin cancer and tends to spread beyond the skin. Once this occurs, melanoma becomes very difficult to treat and cure. Non-cancerous skin growths have the potential to become cancerous. Another precancerous skin growth, cutaneous horns , appears as funnel-shaped growths that extend from a red base on the skin.
Skin cancer is by far the most common cancer in the world.
Most cases are cured, but the disease is a major health concern because it affects so many people. An open or inflamed skin wound that won't heal. A small, dark, multicolored spot with irregular borders either elevated or flat that may bleed and form a scab. A cluster of shiny, firm, dark bumps. Diameter larger than a pencil eraser.
