My father had such severe mouth sores that he could not eat for 2 weeks which eventually led to his organs shutting down which in the end led to his death in 2 weeks time. Please make sure to insist your doctor does something to help with the mouth sores before they get so bad that you cannot eat! Actually, if any loved one of mine gets cancer, next time we are heading to Mexico to the Hoxsey Clinic. I will never again subject a loved one to the poison of chemo again!!!
