Yes, you will have to take some special precautions against infection for at least six hours after bladder treatment with BCG. There is also a risk of passing on BCG infection to those who might have reduced immunity (for example the elderly, pregnant women and those having certain medical treatments).
The BCG vaccine contains a weak form of tuberculosis (TB). The bacteria may be present in your urine for at least six hours after the treatment. It's best to take the following precautions for at least the first 24 hours.
During the first three weeks after intravesical therapy you may feel the need to pass urine often and more urgently.
It's possible that specific complications of intravesical therapy may affect your bladder function. For example if you develop a bladder infection (cystitis) then you will feel the need to pass urine more often and more urgently than usual until the infection clears.
Otherwise, you can expect your bladder function to return to normal after you have made a full recovery. This can take up to three weeks. During this time, your doctor will recommend that you drink plenty of fluids to help flush your bladder to reduce your risk of infection. So as a result, you will be passing urine more often than usual until your fluid intake returns to normal.
Generally, medicines (chemotherapy), surgery and radiation treatments are used to treat cancer. Your treatment options will depend on the type of bladder cancer you have. Your doctor will recommend the best treatment in your particular situation and explain suitable alternatives.
For bladder cancer that hasn't spread into the muscle, there are several treatment options available. These include surgery, chemotherapy and intravesical therapy (treatment with Bacille Calmette-Guérin, BCG vaccine). BCG is usually used to treat the more aggressive type of cancer of the bladder lining.
Generally, chemotherapy and intravesical therapy complement surgery and aren't usually recommended in isolation. Your doctor will recommend the best treatment in your particular situation and explain the benefits and risks of each procedure. Your doctor should explain what may happen if you don't have the recommended treatment and discuss alternative treatment options with you.
You are free to choose not to have the recommended treatment, have a different treatment or not to have any treatment at all. You don't have to give any reasons for your decision but it can help your doctor know your concerns so that he or she can give you the best advice.
If you have any questions, don't be afraid to ask your doctor. It often helps to make a list of the questions you want to ask and to take a close relative or friend with you to remind you of the things you want to know, but can easily forget.
You can always ask for more time to decide about the treatment if you feel that you can't make a decision when it's first explained to you.
