Definition

Any abnormal tissue damage or wound, from tiny skin spots to massive organ damage. Medicine's vaguest term, conveniently covering everything from 'weird bump' to 'catastrophic injury.'

Example Usage

The dermatologist photographed the suspicious lesion, refusing to commit to calling it anything more specific until the biopsy returned.

Origin

From Latin 'laesio,' meaning 'injury' or 'attack'

Fun Fact

The word 'lesion' is so versatile that medical students joke it means 'we noticed something wrong but aren't sure what to call it yet.'
