C43.3: Malignant melanoma of other and unspecified parts of face

You have melanoma (skin cancer) on the face.

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

Melanin-producing cells in your face have multiplied uncontrollably. In the skin, special cells produce a dark pigment. This pigment is to protect the body from sunlight. If a lot of sunlight gets on your skin, then these skin cells produce more pigment. This makes the skin brown. These melanin-producing skin cells also occur in the scalp. There the cells release the pigments to the hair roots. These pigments determine the color of the hair. If these melanin-producing cells multiply uncontrollably, a dark patch can appear on the skin.
