Perineural invasion means that cancer cells were seen surrounding or tracking along a nerve fiber with the prostate. When this is found on a biopsy, it means there is a higher chance that the cancer has spread outside the prostate. Still, perineural invasion does not mean that the cancer has spread, and other factors, such as the Gleason Score and amount of cancer in the cores are more important. In some cases, findings perineural invasion may affect treatment, so if your report mentions perineural invasion, you should discuss it with your doctor. 

Prostate cancer is a disease that is most successfully treated when it is detected early on.  As the research community explores various methods to detecting the disease, PCEC continues to encourage men to play an active role in their health by looking to those trusted sources of prostate cancer testing – the PSA and DRE.
