adjective / noun
incurable
in-KYOOR-uh-bul/ɪnˈkjʊrəbl/
Unable to be cured or remedied.
Her condition is incurable, but treatment helps manage the symptoms.

Etymology
The negative prefix denies the possibility of a cure: something incurable is beyond medicine’s power to heal. Applied to a fault or condition more broadly, it means that no lasting correction is possible.
