Hi Angela--
As I understand TCC is ot a tumor that grows out like a baseball but grows along the transitional cells of the bladder wall (thus the name transitional cell carcinoma).As the tumor gorws along the sides of th bladder, the "walls" thicken with tumor.
Again, as I understand it,you biggest concern is that as this tumor grows it blocks off the kidneys (it's okay to block off one but we all need one kidney to function) . If this should happen, there is nothing that can be done and kidney failure is inevitable (and I know from experience--very quick)
Now for the better news--my Annie was diagnosed 3 1/2 years ago and was given 6 months to live. The only medicine she has taken every day for the past 3 1/2 years is piroxicam. I hope this has been prescribed for your pet (and a few postings up, someone is offering some for free!!!) I've also learned on this board that AAA, if you are a member gives a discount on prescription drugs, even for your pets. (I get our piroxicam from a normal pharmacy.
I wish you all the best of luck with your baby--please take this advice I am about to offer,it will help you greatly. Don't worry right now and don't cry every day--take this time you have and enjoy every second you can with your pet. This time is the only time you have (whether it's six months or six years) don't waste it being sad. (You'll have plenty of time for that one day that I hope is a long way off)
