Good luck to your brother, please google bakingsoda/cancer. I have been on this 7 mo's, i'm now free of mets (previously covered/i'm stg4BC) I do bakingsoda w/honey 1part honey 1/3 part BS. Also, do the puree Asparagus...these do work, don't care what anyone says, i've got lots of friends on these and we all are having great results and they won't interfere w/any medicines. You must keep body PH alkaline, cancer thrives in alkaline body. Diet is the key, remember cancer is not a viral/bacterial or fungal infection, it's anaerobic...diet/nutrition are the key. Please, NO GLUTEMATES. Cancer feeds off glutemates/sugar/soy/red meats. Doc's always want to keep the weight up, but that is feeding the cancer. Eat nuts/whole foods, fruits/ ditch the milk products, cancer feeds off mucus. I went from Stg4/mets in ribs/pelvis/spine/liver/lungs/thyroid and even basal cell carcinoma on my scalp from BC/ As of Feb2, NO METS except tiny spot left in spine, but greatly reduced and know I can eradicate. All this in 7 months from nutritional diet and supplements. I will never have chemo or radiation, was told i'd be dead by last November. I'm still here, all bloodwork perfect, CEA/CA15 T/mkrs are normal, the CA27-29 only 30 points of being normal. It can be done. Research the right supplements for your particular type cancer...google Phytoplankton/Fucoidan/Honokiol. Stay strong for your brother and best to you.
