What is value of palliative care?

Support system: "the goal of palliative care is to relieve suffering and provide the best possible quality of life for people facing the pain, symptoms and stresses of serious illness. It is appropriate at any age and at any stage of an illness, and it can be provided along with treatments that are meant to cure." this is from getpalliativecare.Org.

Providing comfort: Palliative care is provided for somebody who has a life-threatening disease for which there is no cure and that may cause death but it is not clear when. It strives to maintain quality of life of the patient and his/her family.
