PSA0.75 is within the normal range clinically and does not need special treatment, so patients should not worry too much. PSA is prostate-specific antigen, which is an important indicator for prostate cancer monitoring in clinic, and the normal value is <4ng/ml. Prostatitis, benign prostatic hyperplasia and prostate cancer can all lead to elevated levels of total PSA. If this indicator is within the normal range, it is a normal phenomenon, so patients should not worry too much. For people with high risk factors for prostate cancer, especially those with a family history of prostate cancer, this indicator should be tested on a regular basis because it can assist in the early screening of prostate cancer and has a better clinical significance in the evaluation of the treatment effect of prostate cancer. Of course, simply relying on this indicator can not completely exclude prostate cancer, if necessary, we can consider the combination of prostate ultrasound, which has more clinical significance.
