What You Need to Know About Prostate Intraepithelial Neoplasia (PIN)

Sometimes, a biopsy will show prostate intraepithelial neoplasia (PIN). This is not prostate cancer. It is a noncancerous growth of the cells. However, a man who has PIN may have a higher than average risk of getting prostate cancer in the future.

PIN can be either low- or high-grade. Low-grade PIN does not appear to increase the risk for prostate cancer.

High-grade PIN may be a precursor to prostate cancer. It may be present for years before turning into prostate cancer. If you have a high-grade PIN, there is about a 1 in 4 chance you already have cancer somewhere else in your prostate, even if the biopsy did not find it. You may need to have a repeat biopsy and be monitored more carefully in the future.
