Sounds like your dad is on a very good diet, which might carry him through to 100 years old once he gets this cancer thing behind him. MMS often works very quickly with cancer, and had he been able to avoid the medicines given him by the medical doctors he might have been back to normal by now.

There is a woman named Dr. Lorraine Day, Orthopedic Surgeon and Medical School Instructor, who contracted breast cancer. She defied her colleagues, and refused chemo therapy and radiation - eventually devised her own cure. She produced a video telling her story, titled "Cancer Doesn't Scare Me Anymore." A big part of her cure was adopting a raw vegetable diet, and heavy reliance on getting sunlight to produce Vitamin D. But the most valuable thing about this video is having a highly qualified M.D., a former "insider" telling in unvarnished terms about the outright fraud, worthlessness and poisonous nature of conventional cancer treatments. I have this video on DVD, and I recommend you buy it and show it to relatives who think chemo therapy and radiation are the way to go - I promise you it will change their minds.
