Medical professionals provide palliative care to patients in order to provide them with relief from pain, anxiety, and symptoms of chronic diseases regardless of their diagnosis. In the 1950s, many studies were done about the end of life. The aim of palliative care is to provide end-of-life care to dying people. There are about 56.8 million people who need palliative care, so 31.1 million of them require such care at the earliest stage of diagnosis while 25.7 million require it near the end of life.
