Frequently asked questions

What is the difference between untreatable and incurable?

They are close but not identical. "Incurable" means the condition cannot be permanently cured, though symptoms may still be eased or controlled. "Untreatable" is stronger: it means there is no effective treatment available at all, not even one that manages the symptoms. Many incurable conditions are very treatable.

Does untreatable mean terminal?

No. "Terminal" means a condition is expected to end in death, usually within a foreseeable period. "Untreatable" only says that no effective treatment exists — which may describe a condition that is uncomfortable or limiting but not life-threatening.

What is the opposite of untreatable?

The direct opposite is "treatable," meaning a condition that responds to available medical care. "Curable" is stronger still: it means the condition can be removed entirely, not merely managed.

What is the meaning of untreatable?

"untreatable" (adjective) means of an illness, injury or condition: not able to be helped or cured by any available medical treatment.
