PSA density is the amount of PSA per gram of prostate tissue. All prostate cells produce PSA. Prostate cancer cells usually cause more PSA to be released into the blood stream. As such, given the same size prostate in both a normal man and one with prostate cancer, in general, the patient with prostate cancer will have a higher amount of PSA per gram of tissue then a normal individual.
