What are the diagnostic methods of prostate cancer?

Prostate cancer is a malignant tumor that occurs in male prostate tissue.

1. Transrectal ultrasound examination. Transrectal ultrasound is to probe the ultrasound probe into the rectum like digital rectal examination. This transrectal ultrasound examination method can increase serum PSA, so it should be carried out after blood drawing. Transrectal ultrasound can show the nodules of prostate lesions.

2. Serum PSA test. This is the most common examination method for prostate cancer. Under normal circumstances, PSA in blood is lower than 4 μ g/ml, and it rises when suffering from prostate cancer and other prostate diseases, which is the most sensitive index for screening prostate cancer at present. If the PSA level is higher than 4 μ g/ml, it should be rechecked once, and rectal digital examination is not needed. If it is still elevated, excluding the influence of inflammation or other factors, there may be prostate cancer, and prostate biopsy should be performed again.

3. Digital rectal examination.
