Hi there,Please be patient, as I may be in the operating room or driving but will get back to you ASAP.
1. If it does not come down with antibiotics, then your husband will definitely need a prostate biopsy to rule out cancer. About 1 out of 3 biopsies come back positive for prostate cancer. So, just because the PSA does not come down does not mean he has cancer but needs it ruled out. His chancer would roughly be 1 in 3. The PSA level will not determine treatment he may need, but the actual biopsy results themself. If he does have cancer, there are many options based on how significant the cancer is. One of those options is to just wait and do nothing. Hope this helps.
