Hello. My father has been diagnosed with stage 4 metastatic cancer.  The cancer is in his lungs. Lymph nodes.  Liver. Colon...and yesterday it was confirmed in his spine. Shoulders legs and elbow.  After a long appointment with his oncologist and all of our family, dad has refused treatment.  He was only diagnosed 6 weeks ago and is already very tired. How long will he live? The doctor says a few months.  I just dont want to see him suffer.  He is 84 years old and up until now...very fit and healthy.
