Col;
I would seek alternative therapy. Go to garynull.com and try and find a specialist that treats with holistic and alternative treatments.
I am not sure were you live but go to acam.org and try and find someone. My Mom has stage 3C her cancer has spread in the abdomen, Liver and also onto the lungs and who knows were else. Mom who has a peg tube cannot be feed because there is a tumor in the small intestine; she is in a hospice and on morphine not much we can do other than surgery which she is too weak for. I told my parents to go the Holisitc route 6 months a go to keep the cancer in check but they refused. I may have someone from an Alternative treatment center run a Vitamin C drip that may be my only hope. Hopefully the Hospice will allow this treatment. Also there is something called the Geipe therapy which may be helpful. Good luck I hope thigs turn around for you soon.
