@concernedadvocate Welcome to Mayo Clinic Connect! You, obviously, are very concerned about your father and the treatment he is being given. I was a nurse on an oncology unit for about 11 years and we had many situations just like you are experiencing. We actually had an educational inservice on the situation, focusing on the law as it concerned the patient and doctor’s rights. The doctor doesn’t make his decision lightly. He asks his peers for advice, reads the patient chart over and over, and weighs all of this before making a decision.
You and your father can ask for further treatment, but you will only get it from a doctor who doesn’t agree with the no treatment decision. You can move your father to another hospital, if he can find another doctor willing to accept him and his wish for further treatment.
I know this is not what you wanted to hear, but this is the way it is today. I certainly agree with @colleenyoung about including an oncology social worker in the discussions. You might also include the hospital chaplain ( they are non-denominational) and excellent in talking to the patient and family.
What are your father’s wishes?
