What is the focus of palliative treatment?

The primary focus of palliative treatment is to alleviate symptoms associated with serious illnesses. Palliative care is intended for patients who are facing chronic or life-limiting conditions and aims to improve their quality of life by addressing physical, emotional, and psychological needs. This type of care does not aim to cure the disease but rather to manage symptoms such as pain, nausea, and fatigue, while also providing support for patients and their families.

In contrast, other options emphasize different aspects of health care that are not the central tenet of palliative treatment. For example, curing the disease pertains to curative treatments, preventing disease onset relates to preventive medicine, and improving nutrition may be part of general health care strategies but does not specifically capture the essence of palliative care's objective. Thus, alleviating symptoms represents the correct answer, aligning with the fundamental goals of palliative treatment.
