Liver Flush for cancer patient

My 75 year old father had Gallbladder Cancer which has went into the bile ducts of the liver. He had the gallbladder removed, and then a month later he had to have a metal stent put in the bile duct, the cancer had strangled the duct. He is in terrible pain, no pain meds have helped. Would it be safe to do a liver flush? I don't want to do anything that would cause him more pain. The Gallbladder Cancer had eatten a hole through the gallbladder and there were stones every where in the stomach and along the liver. Could he possibly still have a stone some where that is causing the pain? Our next step would be to do a celiac plexus block. The medical doctors have nothing to offer. We have been on the Hoxsey program for the past 3 weeks. Tweet
