**2.1 The purpose of palliative care**

The goal of palliative care is to restore the functional capacity of a patient by being sensitive to the cultural and local values, beliefs, and practices of the individual, to alleviate pain, and to improve the life quality by controlling the symptoms [6, 11, 12]. In other words, the purpose is to reduce or eliminate the symptoms of the disease without any further examinations when the cure is no longer possible in the disease. Indeed, what the WHO expected from palliative care team is to respect patients and their relatives and to consider their wishes. This expectation should be interpreted as providing health care to the patient and his/her relatives that will ensure their well-being regardless of their age, economic or social status, and disease characteristics [1, 4, 7, 9, 13].
