KK: /mɛləˈnoʊmə/
A type of skin cancer that develops from cells that produce pigment, often appearing as a dark spot or growth on the skin.
The doctor diagnosed her with melanoma after examining the unusual mole on her arm.
Melanoma is formed from "melano-" (from Greek "melas", meaning black) and "-oma" (from Greek "oma", meaning tumor or swelling). The word refers to a type of tumor that is characterized by dark pigmentation, typically associated with skin cancer.
Think of 'melas' meaning black, which helps you remember that 'melanoma' refers to a dark-colored tumor.
