Prostate PSA 18ng/ml can still be lowered, but the specific condition is closely related to the condition of the prostate disease itself, and part of it needs to be controlled through standardized treatment. PSA is known as prostate specific antigen, the rise of the corresponding index is related to prostate cancer, prostate hyperplasia and prostatitis, under the standardized treatment of clinicians, the disease is effectively controlled, the corresponding value will decline. If the PSA value reaches 18ng/ml, the probability of belonging to prostate cancer is very high, and the corresponding value can be reduced by controlling the disease through surgery and radiotherapy. PSA value of 18ng/ml with prostate swelling and hematuria and other symptoms, we need to consult a doctor in time to observe and diagnose the cause of the disease and then carry out standardized treatment under the guidance of clinicians to avoid delaying the condition.
