PSA is the abbreviation of Prostate Specific Antigen, PSA is greater than 4 and less than 10, there is a possibility of lowering. Elevated PSA is a common tumor marker, with a normal value of <4ng/ml. Significantly elevated PSA levels are often seen in prostate cancer, which is often >10ng/ml. In addition, benign diseases such as prostatitis and benign prostatic hyperplasia can also have mild elevations. Prostate massage, ultrasound and puncture biopsy operations can cause a significant increase in PSA levels. Patients with PSA greater than 4 and less than 10 are more likely to be diagnosed with benign prostate diseases or have elevated levels due to certain manipulations, etc. In the former case, active treatment is needed, and the PSA can be lowered when the condition improves. In the former case, only active treatment is needed, and the PSA will drop after the condition improves. If the PSA is affected by other factors such as prostate massage, it may also drop after review. It is recommended that the patient should consult the doctor in time, have the prostate ultrasound examination, prostate fluid examination, urine routine examination, secretion examination, etc. to clarify the cause of the disease, and actively treat the disease and monitor the PSA value regularly.
