I am a 57-year-old man whose prostate is swollen and painful. This has happened before and I have had two prostate biopsies - both negative for cancer - in the past two years. I am slim and active, and do sport twice a week. My PSA is around 7; it has been higher. My doctor has scheduled another biopsy for next week. My questions are: 1) Do I need this biopsy, 2) Is it possible I have BPH and/or prostatitis, 3) if so, what should the doctor do to rule out any of the above, 4) The fact that I have had this painful condition several times before without cancer being found, is a biopsy necessary? 5) Could these biopsies cause, or irritate in some way, cancer (if I have it)? I look forward to your answers to these questions. Thanks
