Medical → Metastatic melanoma

Skin melanoma is the most malignant type of cancer. It usually begins in a mole. When there is distant metastasis (spread of cancer from one organ or part to another non-adjacent organ or part), the cancer is generally considered incurable. Some patients with metastatic melanoma do not have an obvious detectable primary tumor. The five year survival rate in metastatic melanoma is less than 10%.
