Hello @benzino.
You have been doing this for a long time and it gets tiresome, along with the constant worry of a worsening situation. My husband opted for a neobladder surgery instead of regular monitoring. I think you should seek out a second opinion in your situation. BCG is a form of local immune therapy and may be an option to another doctor. There has been a shortage of the drug in the recent past and that might have affected your doctor's opinion. If your cancer is really recurring faster, then there should be a good discussion about what else you can do to maintain your bladder. Do you have a larger cancer hospital or University associated hospital within a reasonable distance where you could request a second opinion?
