Clinical Information

Melanoma is a type of skin cancer that develops specifically in melanocytes, which produce melanin.
Doctors and researchers haven’t identified the specific cause of melanoma. However, being exposed to ultraviolet (UV) radiation from tanning lamps, tanning beds, or sunlight can increase one’s risk of developing melanoma. Aside from that, unusual moles and medical history can also impact the risk of melanoma.
Typically, the first signs of melanoma are a change in a mole that already exists, pigment, or unusual-looking growth on one’s skin.
A physical examination is usually done on a patient to diagnose melanoma.
Treatment will vary depending on the stage of melanoma. Early-stage melanomas may only require surgery for treatment. While advanced stages may require immunotherapy, chemotherapy, radiation therapy, etc.

Synonyms Include:

Skin tumor
Skin cancer
Malignant skin neoplasm
Malignant melanocytic neoplasm
Invasive melanoma
Cutaneous melanoma
