The normal range of SPA within one year after prostate cancer surgery can indicate that the disease has been cured, but there is a risk of recurrence of the disease, which requires regular review. PSA generally refers to prostate specific antigen, through this index can diagnose whether prostatitis, benign prostatic hyperplasia, prostate cancer and other diseases exist, but this index can not be used as the basis for diagnosing whether there is prostate cancer or not. For prostate cancer patients, if the prostate-specific antigen is within the normal range within one year after the operation, it can be said that clinical cure is achieved. For postoperative prostate cancer patients whose prostate-specific antigen is within the normal range within one year after surgery, the diagnosis can be further confirmed by combining with other examinations, such as prostate pathological biopsy and magnetic resonance imaging. Since there is a certain risk of recurrence of prostate cancer, even if it is clearly cured, regular medical checkups are still needed. It is suggested that prostate cancer patients should adjust their mindset and keep themselves happy physically and mentally. Pay attention to regular medical checkups to monitor the physical condition. If there are any uncomfortable symptoms after the surgery, they should go to regular hospitals for medical treatment in time.
