The term [cancer] is Latin and means "crab". The word was first used by Galen of Pergamon (129AD - 200AD) who used it to describe the crab-like appearence of the veins of a cancerous tumor, probably a breast cancer. Galen said "... as a crab's feet extend from every part of its body, so in this disease are the veins distended, forming a similar figure". The term cancer is also used in other applications, such as astronomy (Tropic of Cancer) and astrology, as in the zodiacal sign of Cancer.
The Latin term [cancer] was probably pronounced "kanker" and this may be the origin of the term [canker] to refer to ulcerations around the mouth or angles of the mouth, canker sores. This is also probably the origin of the term [chancre] used for some dried-out sore wounds.
Greek terms merged into the New Latin, so the Greek terms derived from [karkinos] also made it into modern medical terminology.
|The word [cancer] is used today to denote a malignant tumor. There are variations of the term using the root term [-carcin-] as in [carcinoma].
