means A medical treatment that boosts or redirects the body's own immune system to find and attack disease, especially cancer, rather than attacking the disease directly with drugs or radiation.

from A straightforward modern compound: 'immuno-' from Latin immunis (originally 'exempt from public service or burden,' later 'exempt from disease'), fused with 'therapy,' from Greek therapeia, meaning 'treatment' or 'service done to the sick.' The word itself is young, 20th-century coinage, rising alongside the science — as researchers moved from asking 'what drug kills this?' to 'how do we wake the body's own defenders?' Fittingly, 'immunis' once meant being excused from a duty; immunotherapy's whole premise is making sure your immune cells no longer get a pass on recognizing cancer as a threat.
