I was diagnosed with non-invasive low grade bladder cancer in 2013. (one polyp) For the first two years after had cystoscopies 4X/year. , then 2 years at 2x/year for an additional two years. At that point (4 years post cancer and no reoccurrence) I thought yearly cystoscopes were the norm. My urologist prefers cystoscopies every 6 months rather than yearly going forward. He relates that in his experience he has seen cancer return even many years from original diagnosis and believes I would be better served with cystoscopies every 6 months. I am now 8 years post diagnosis with no reoccurrence and I'm certainly thankful for that, but was wondering if perhaps my urologist is being overly cautious.
