I have been research PIN for you to no avail. My husband
had prostrate cancer and there is nothing in all his pamplets about PIN
either. I would suggest that you call the National Cancer Inst. at
1-800-4-CANCER. Warmly, lillian
My PSA went up to 9.1 and the free PSA was
16%. A second biopsy revealed PIN. I'm not familiar with
this. I thoght I was dealing either with BPH or Cancer. Any help
with the definition of PIN would be appreciated.
