There is a LOT about BCG on this Forum. If you use the search function at the top right of this page you will find a lot to read about. BCG is very do-able although it does have side effects. You will be asked to try to keep it in your bladder for about 2 hours.....not always easy to do and it is no big deal if you have to void early. I live about 25 minutes from the doc's office and was always able to get home.
The things that happen after the instillation are usually urgency, burning, and sometimes blood in the urine. The most common "side effects" are, first, fatigue. For the first few installations that is about it. The side effects DO increase as the treatments continue and this indicates that your immune system is kicking up which is exactly what you do want to happen. These discomforts..burning, urgency, and fatigue usually...are certainly easier to bear than the side effects from chemotherapy!
Remember when you read other's experiences with BCG in Forum posts that people who have no problems are not the most likely to post. We are very fortunate to have BCG as it is a real life-saver for those of us unfortunate enough to have high grade bladder cancer.
Please ask any questions that you may have. You will do well
