What therapy is specifically aimed at relieving symptoms in untreatable conditions?

Palliative therapy is specifically aimed at relieving symptoms and improving the quality of life for patients with serious, often untreatable conditions. It focuses on alleviating discomfort caused by the condition itself and any associated treatments, rather than attempting to cure the disease. This type of therapy can be applicable across various stages of illness and is not limited solely to end-of-life care.

In contrast, sustainable therapy usually refers to treatment approaches that have long-term benefits and are viable over an extended period. Chronic therapy involves the management of long-term health conditions through ongoing treatment but does not emphasize symptom relief specifically. Interventional therapy typically involves procedures or interventions designed to treat a condition more directly than merely managing symptoms. Thus, palliative therapy stands out as the correct choice for addressing symptoms when a cure is not possible.
