This section is for teenagers and young adults. It is about a type of skin cancer called melanoma. If you are looking for information about melanoma in people of all ages, you can read our general information about melanoma.
Melanoma develops from cells in the skin called melanocytes. The cells start to grow and divide more quickly than usual. In melanoma, the melanocytes start to spread into the layers of skin. When they grow out of control, they usually look like a dark spot or unusual-looking mole on your skin.
It is important to know the symptoms of melanoma, so it can be found and treated as early as possible. Early-stage melanomas (called thin melanomas) are usually cured with surgery.
