Reliv is not a cancer supplement but a food supplement that gives the body the nutrition it needs to heal itself.It is good for many different illnesses and prevention.I have been using it for about 7 months and have got amazing results with fibromyalgia,CFS,IBS and migraines. My step-mom has kidney cancer,she had one of her kidneys removed almost 2 yrs ago and never recovered from the surgery.She just had no energy,had trouble keeping anything down even water at times,and just felt horrible.She is feeling much better since taking reliv and is not spending so much time in bed......themommie
