That is good progress, Stephano! No, that isn't too long to wait. It is very important that the bladder has time to heal before BCG treatments. There is a lot of information about BCG on this website.....
Look under the "Non-invasive Bladder Cancer" category in this Forum.
No, BCG does not work for everyone. But it does work for a very high percentage of patients. We are so lucky to have it. If it does not work, there are other treatments available.
A good diet is never a bad idea, but I have not seen any scientific evidence that vegeterianism has any effect on bladder cancer. The fact is that whatever caused the bladder lining to become somewhat unstable and susceptible to become cancerous probably started many many years ago. We do not know what causes bladder cancer in most cases. Smoking is one factor that is known to be involved. But for most of us, we have no idea.
