Taken from Wikipedia:
Palliative care (from Latin palliare, to cloak) is any form of medical care or treatment that concentrates on reducing the severity of disease symptoms, rather than providing a cure. The goal is to prevent and relieve suffering and to improve quality of life for people facing serious, complex illness. Non-hospice palliative care is not dependent on prognosis and is offered in conjunction with curative and all other appropriate forms of medical treatment. It should not be confused with hospice care which delivers palliative care to those at the end of life. In the UK this distinction is not operative; hospices and non hospice based palliative care teams both provide care to those with life limiting illness at any stage of their disease. (See "History" and "Practice" below for additional information on hospice and hospice care.)
