OK...now i'm thinking out loud. I noticed you're in NY..you've got some of the best uro's and surgeons in the country at Memorial Sloan in NYC. I don't know where you are in the state but i went there from Ohio and I'm pretty sure they saved my life. You really don't even want to mess with the probability that it might be cancer.....and its widly known that the best uro's and surgeons are associated with major facilities ..university or cancer centers.
And if you go to your local hospital the first thing the technician is going to ask you is do you have any allergies to dyes....and you're going to say yes...and either she/he will know what to do or not. A CT scan without dye may show a tumor but it will not be defined without the dye. If you should have CIS as i did it does not show up and was only picked up during the Trans Urethral Resection or TURB. I also had a local uro as my brain was not functioning remotely at the time do my TURB....brain cells kicked in and i called MSK and they got me in within 7 days to Dr. Harry Herr..quite reknown. He did a second TURB within 9 days of the first and got all the margins my first uro left in there thus preventing re-seeding and like i said...saving my life. I was still diagnosed as T2 Grade 2 and bladder needed to come out but the interesting thing was when it did come out there wasn't a cancerous cell in it. That i attribute to Dr. Herr. It would have come back as thats what this cancer does...it just seems to want to come back.
Ok worst case scenario there. But my point is....find out what you have from the best and be treated by the best. The entire team is important here from surgeon, to pathologist, and everyone inbetween taking into account all the meds you are taking.
