“An abscess is a 'going away' — Latin abscessus, from abscedere, to go away or withdraw. The word describes what healthy tissue does: it withdraws from the infection, leaving a pocket of pus behind.”
Abscessus in Latin means a going away, a departure, from abscedere (to go away, to withdraw), from abs- (away from) + cedere (to go, to yield). In medical Latin, the word described the process by which healthy tissue recedes from infected tissue, creating a walled-off cavity that fills with pus. The abscess is not the infection itself. It is the body's containment strategy — the tissues go away, leaving the infection trapped in a pocket.
Hippocrates described abscesses and their treatment around 400 BCE, and the fundamental intervention has not changed: drain the pus. 'Ubi pus, ibi evacua' (where there is pus, evacuate it) is a surgical maxim that has held for twenty-four centuries. Incision and drainage remains the primary treatment for abscesses in 2026. Antibiotics help, but the pus must come out. The ancient advice works.
The word acquired metaphorical uses. An abscess of corruption. An abscess of discontent. The metaphor is precise: a walled-off pocket of something bad, growing under the surface, requiring opening to heal. Political commentators use the word when they mean a hidden problem that has been contained but not resolved.
Dental abscesses, peritonsillar abscesses, and brain abscesses can be life-threatening. Before antibiotics, an untreated abscess could lead to sepsis (blood poisoning) and death. The body's containment strategy — walling off the infection — works as a short-term measure. Long-term, the pocket must be opened. The word abscessus — going away — describes both the tissue's response and the treatment: make the pus go away.

An abscess is the body fighting an infection by containing it — building walls around the enemy. The strategy works temporarily. The infection is isolated. But the pus accumulates, the pressure builds, and eventually the abscess must be opened. The twenty-four-century-old surgical advice — drain it — has not been improved upon.
The Latin said going away. The tissue goes away from the infection. Then the surgeon makes the pus go away from the tissue. The word describes both the problem and the solution.
