'resection' originates from Latin, specifically the word 'resectio,' where 're-' meant 'back' and 'sectio' meant 'cutting.'

'resectio' transformed into the French word 'résection,' and eventually became the modern English word 'resection' through Middle English.

Initially, it meant 'cutting back,' but over time it evolved into its current meaning of 'surgical removal of part of an organ or structure.'
