Before signing such a form, patients should read it carefully and ask the doctor any questions they might have. Patients have the right to make decisions about their own treatment. These decisions may change over time. In the face of worsening disease, some patients may want to try every available drug or treatment in the hope that something will be effective. Other patients may choose to forgo aggressive medical treatment.
Many patients turn to family members, friends, or caregivers for advice.
But it is the patient's decision how much or how little treatment to have. Sometimes a patient is unable to make this decision, due to severe illness or a change in mental condition. That is why it is important for people with cancer to make their wishes known in advance. Advance directives provide a way for patients to communicate their wishes to family, friends, and health care professionals and to avoid confusion later on, should they become unable to do so. Ideally, the process of discussing and writing advance directives should be ongoing, rather than a single event.
