Hi, My Dad has just been told he has cancer in his lungs & liver. He has been drinking 12ozs.of Xango a day for 2 weeks. He has decided to try the 21 day challenge consisting of 1 bottle a day. He will find out tomorrow at Wooster Cleveland Clinic if his liver will tolerate chemo. If not the Dr. said he has only 2 months. We feel the Xango will be worth a try. Could you tell me if you have heard of other cancer patients drinking Xango and what their results were! Thank you for any info you can provide. Sincerely, BonnieV
