Hello, this is my first post. I had bladder cancer removed July 2020, but because of COVID my BCG treatment did not commence until April 2021, I am 75 and are otherwise fit and healthy. My first 6 instillations were fine with little or no side effects, but number 7........wow! Following this instillation I had the full works of problems (and still have)  - frequency, 40-50 times per 24 hours, trouble getting started, problems with the flow (sometimes none) and severe pain passing and real pain post attempt. I am under the care of the Hospital that performed the initial operation and a am few days away from my next review. I would like to hear from anyone who has had to leave the programme in similiar circumstances to my own Thank you.
