I to was diagnosed with stage 4 stomach Cancer that had already spread to my liver...that was four years ago this coming spring,
I just got my latest CT scan results back on the 20th, I am still Cancer Free, the Oncologist even asked me to bring in some information about the alternatives I have been taking as he even admits that I am "one for the books" he thought I would be dead within 8 months of diagnosis. I have been taking Essiac and Pau d'arco, they are relatively inexpensive compared to many other alternatives and are brewed into decoctions or "teas". The Cancer I had was adenocarcinoma of the stomach with a tumor at the junction of my esophagus ( please excuse my spelling), I know there are several different kinds of stomach Cancer, all I know is I would not be here today if it wasn't for these teas.
I wish your father the best of health, remember there is no such thing as false hope...you either have hope or you do not...I strongly advise having it...Cancer can be Beaten!
I will post a couple of links below where you can read more about the "teas".
