If the PSA is higher than normal, it may be cancer. Generally speaking, there is no such expression as “several times higher than normal to be cancer”, and you should consult a doctor to confirm the diagnosis in time. PSA refers to prostate-specific antigen, which is a single-chain glycoprotein secreted by the prostate gland and exists in the epithelial cells of prostate ducts. The serum PSA level of prostate cancer patients is significantly higher than the normal value. The normal value of PSA is generally 0 to 4ng/ml. If PSA exceeds the normal value, there is a possibility of cancer, and the higher its value, the higher the possibility of having cancer. However, cystoscopy, urethroscopy, surgery through the urethra, and anal fingerprinting with a catheter in place may cause a transient increase in PSA, which is not necessarily cancer. Therefore, it is necessary to do further examination to clarify whether it is cancer or not. The patient can be clear through the prostate puncture biopsy lesion. When the PSA is higher than the normal value, attention should be paid to it, and timely consultation should be made to clarify the diagnosis.
