However one of the concerns that doctors have about taking testosterone, or similar hormones like DHEA or hormones used for body building, is that they might stimulate, or speed up the development of prostate cancer. Your history of having taken testosterone would certainly make me urge you even more to have further evaluation. The ultrasound you are scheduled for is almost certainly a transrectal one, in which the ultrasound probe is inserted into the rectum. This provides a very clear picture of the gland. Its total volume can be calculated and small nodules that might represent cancer can be seen.
Needle biopsy using the ultrasound picture for guidance can be very precise.
Even if your ultrasound shows no nodules though, I believe that at this level of PSA most experts would suggest that you have random, that is unguided, biopsies done. Although it is disputed by some, most urologists believe that the cure rate of prostate cancer detected early by PSA is quite high. If indeed this is what your biopsy shows, you may wish to ask your urologist for the specific prognosis in your case. This is one doctor who makes housecalls. People with lupus often find themselves in chronicpain, but there are ways to find relief.
