The first thing you should do is educate yourself about chemotherapy. I recommend the book “Questioning Chemotherapy” by Ralph W. Moss, who used to work as a lead researcher at the National Institute of Health. Ralph will give you the straight story on chemotherapy. Whether you decide to undergo chemotherapy or avoid it, Bio-Algae Concentrates will improve your results. There are no known contra indications while taking BAC, although some oncologists may want to discourage you from using them during your treatment, thinking that they are like other isolated supplements and/or not knowing that they are a well balanced and naturally synergistic whole food.
