ETYM Latin, from tumere to swell: cf. French tumeúr. Related to Tumid. Usage US
(Alternate spelling: tumour). An abnormal new mass of tissue that serves no purpose; SYN. tumour, neoplasm.
Overproduction of cells in a specific area of the body, often leading to a swelling or lump. Tumors are classified as benign or malignant (see cancer).
Benign tumors grow more slowly, do not invade surrounding tissues, do not spread to other parts of the body, and do not usually recur after removal. However, some benign tumors can be dangerous, such as in areas like the brain. The most familiar types of benign tumor are warts on the skin. In some cases, there is no sharp dividing line between benign and malignant tumors.
