Things that have been approved immunotherapy in the United States are Opdivo which is the sibling of Keytruda. Like a male female relationship. This is one avenue to ask your doctor about. If they don’t offer much hope, there is a Dr Ralf Kleef in Austria who treats with immunotherapy combination drugs in reduced amount so that it is more safe.
In the meantime if you are being only told about chemotherapy, I would highly recommend learning about coffee enemas. They cause the liver to detox quickly. A liver can completely regenerate itself within 9 months. Also check out Chris Warks website Square One. It is a natural approach..... helping yourself in my opinion is using the best of both worlds. I do not agree with using traditional chemo with Stage 4 colon cancer as it is a very low success rate. Dr Kleef is an oncologist so he uses immunotherapy but he is integrative and also uses natural things like mistletoe and a unique treatment to I crease body temperature safely to kill cancer cells. Just know there is so much stuff out there. Stop all sugar that doesn’t come from fruits and vegetables in their natural form , stop all processed foods immediately. These are all my personal opinions and aren’t meant to be used as medical counseling, but so do want you to be aware of many things around you so that it isn’t cookie cutter treatment. Like I said the results for golfos and Folfuri in Stage 4 colon cancer speaks for themselves. I pray you have a chance to pray and seek Gods guidance for you and remember through faith you can be healed. The Bible says it and the Bible does not lie.
