If a bone scan or CT indicated anything it would seem to me a little late to be doing the biopsy as cancer would already be out of the prostate.
I have asked myself these questions many times already since finding out I had PCa.
THings I would do now that I did not do.
1. Insist that a minimum of 12 samples be taken with the biopsy. 1997 and 2000. If I remember right there were only 6 samples on each. Both negative but the one in 2000 indicated PIN. The only thing I noted was beneign.
2. In 2004 when my new urologist said he would order a biopsy if I had not already had a negative one in 2000, I would have made him order one and again, at the minimum, 12 samples. This even though my PSA was welll within normal range after taking antibiotics for an infection in the prostate.
To me the DRE and biopsy is a small price to pay for early detection.
