The surgical removal of tissue, organs, or abnormal growths from the body. This procedure involves cutting out the targeted area completely, often to treat cancer, infections, or other pathological conditions.
From Latin 'excisio' meaning 'a cutting out,' derived from 'excidere' (ex- 'out' + caedere 'to cut'). The term has maintained its literal meaning of cutting something out since ancient Roman medical texts.
