 For some diseases, such as advanced cancer, there may be no treatment of the disease which can prolong the life of the patient or improve the patient's quality of life.In such cases, standard medical advice would be for the caregiver and patient to have conversations with the doctor about the risks and benefits of treatment and to seek options for palliative care or hospice.During end-of-life care the caregiver can assist in discussions about screening which is no longer necessary.
