Vince,
I am T1 G3 also. My Uro kept sending me back until there was enough muscle tissue for a good
sampling. This is of utmost importance!!
My recommendation based on my own experience is to go get a second opinion at a teaching hospital.
Ask a top Urological Surgeon to do the biopsy and make sure there is plenty of muscle tissue.
My second opinion doctor at UNC Hospital in Chapel Hill was part of a multidisciplinary team which
means that after my biopsy and CT scan, a whole bunch of different head doctors from various departments
(Oncology, Radiology, etc) sat around a table and discussed my case to form a consensus on the safest direction to take.
I urge you to get a second biopsy with a deep muscle sample. The fact that you are having recurrances while on BCG is not such a good thing with your Stage and Grade.
Your Bud,
Rosemary
