I am 54 and my PSA was a 4.3, up from a 1.2 just a few months prior. However, my doctor was not alarmed at all. My doctor is one of the four main cancer surgeons at our clinic. A T2 usually means that the tumor could be felt during a digital rectal exam? Do you know if this was the case? I think the biggest concern for the doctor (and patient) is if the cancer has spread beyond the prostate in terms of urgency. Your explanation leads me to believe the biopsy report doesn't indicate that is the case.
I'm not sure if the doctor is concerned about abnormal cellular structure which may lend to the doctor's sense of urgency. Have you sought another opinion? I know that costs money, but it could get you more information and lend some comfort in choosing a treatment option.
