A surgical operation to remove haemorrhoids, typically performed when they are severe or cause significant symptoms.
From haemorrhoid + Greek '-ectomy' (meaning 'cutting out' or 'surgical removal'). This combining form appears in many surgical procedure names like appendectomy or tonsillectomy.
The -ectomy suffix comes from Greek and appears in hundreds of medical procedures—whenever you 'cut out' a body part, you're using ancient Greek terminology. It's one of the most productive word-building elements in medicine.
