The Roller Regimen Program as outlined in "Lower Your PSA in 28 Days and Combat Prostate Cancer" consists of eating a heart-healthy diet (real food from the grocery store), taking some over-the counter supplements, and using the roller to massage the specific acupressure point (on the hand) for 10 minutes, 4 times a day, for only 28 days. Gentlemen, most surgeries or treatments are scheduled for 30 to 60 days out, giving you ample time to try the Roller Regimen Program while you wait. That's what my husband did and when we went back for pre-surgery testing and biopsies, the tumors (Stage 1 Prostate Cancer) were gone; and his PSA was reduced by 50% - from a 5.0 to 2.5. We were successful in lowering his PSA an additional 3 times by as much as 60% in 28 days, and 10 years later he is still cancer FREE! This program works! Try it for 28 days, what have you got to lose? If you are not experiencing prostate problems, you need only to follow the basic guidelines of the diet as described in the book to maintain a low PSA. Please be advised that the diet is not one of deprivation! There are no counting calories, measuring, etc., unless of course, you are trying to lose weight, and then it is minimal.
