Melanoma is the most dangerous form of skin cancer and develops when unrepaired DNA damage to skin cells (usually from sunshine or tanning beds) triggers mutations that lead to skin cells multiplying rapidly to form tumors. While melanoma is not the most common skin cancer, it is the most deadly since it can spread to other parts of the body where it is harder to treat.
If melanoma is recognized and caught early, it is almost always curable. That is why it is so important to understand the early warning signs of skin cancer.
