We have learned via my husband's highly aggressive muscle invasive bladder cancer that a lot depends on how aggressive the tumor is, and obviously progression. The superficial tumors seem to be well controlled for even years with repeated TUR procedures. My husband had BCG treatments which is a type of immunotherapy infused into the bladder regularly, but his tumor was resistant. Oral Keytruda was also tried but failed. Gemcitabine infusion into the bladder was offered. After 3 years of repeated Cancer cells and TUR procedures at MAyo Clinic Rochester, he chose to have a radical cystectomy with neobladder formation. It's been a tough road with complications, but currently cancer free. I hope you catch yours early and can continue the minimally invasive procedures to control it. Good luck.
