C43.9: Malignant melanoma of skin, unspecified
You have melanoma (skin cancer).
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.
Your melanin-producing cells have multiplied uncontrollably. These cells produce a dark pigment (melanin). 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. If these melanin-producing cells multiply uncontrollably, then a dark spot can be seen on the skin.
