Larry Bans: PSA is a protein that’s produced in the prostate gland and prostate cells both benign and malignant produce PSA. The higher the PSA, the higher the risk that there might be prostate cancer, however, PSA’s can be elevated in cases where there’s infection or inflammation in the prostate - that’s called prostatitis. When we see a patient who has a PSA of 29, it could mean that there’s significant prostate cancer, but it also could mean that there’s prostatitis present. I’ve actually seen PSA’s well above 100 in people with infection or inflammation, and not cancer. So this needs to be sorted out. It’s a concern, but it does not absolutely mean there’s cancer present. You have to make sure that it’s not malignant, but it could be something else, such as infection.
