Thanks so very much. I have asked my clinicians who say that there is no causal path between sacharin use and bladder cancer. I found some peer-reviewed literature that finds the same except for one that noted an assoication between very high sacharin use and bladder cancer. When I looked it up, I was suprised that the recommended not-to-exceed dose of sacharin was only 10 packets a day. If there is a lifestyle factor that I can change to decrease my recurrence risk, I would, but I don't want to unnecessarily as it is one of the few luxuries I afford myself. Just wondering if there are any others out there like me and if quitting sacharin was useful to them. Many thanks!
