Hi Dottie; my name is Sue. I used the cesium also for breast cancer. How long have you been with your sister caring for her and away from California? My daughter lives in California; Manhattan Beach and I love it there. It has perfect weather. . .anyway to get back to the cesium, may I say your sister is very fortunate to have you to care for her. I did it on my own. Did you use liquid or capsule cesium? I used capsule and have heard people who take the liquid seem to have less side effects. I felt MARVELOUS the first couple of days on it. I took coral calcium (9 per day and coq10 and D). My tumor had gotten painful (I had a lumpectomy a year ago February and refused further oncology - mine was agressive and not estrogen receptive so basically the radiation and chemotherapy would have just bought me time.) It claims the cancer is dead within 24 to 36 hours (which I found pretty hard to believe) but in 36 hours my pain was gone. At the two-week mark I got sick and had to stop for a couple of days and then resumed to complete the 33 days. I think all of the friendly bacteria got stripped from my colon. At any rate, the tumor did not go away and started growing again and now I have three. I have been researching - spent alot of $ on the MGN-3 which did not seem to help and have been considering the Graviola. I wonder if there should be a longer time on the cesium or continued at a lower dosage. Are you a nurse? I look forward to your answer.
