Hi Eddie
There are 5 stages. TA means tumor attached to inside bladder wall only. T1 means tumor attached to lining of bladder. T2 means tumor did reach the muscle of the bladder and is considered invasive. T3 means the tumor has reached the outside of the bladder in the fatty tissue and possible lymph notes. T4 means the tumor has spread to other organs.
Now having said all that, normally low grade tumors are TA, some possible T1 usually unlikely but possible, and very low odds of T2 but again possible.
The vast majority of low grade tumors are stage TA.
Your stage and grade will be shown on your pathology report which you should ask for a copy from your doctor.
I hope I have not confused you.
