Prostate finger examination, which is the most conventional examination method, that is, a professional doctor enters the anus with his index finger and touches the prostate to understand the size, texture, density, the presence of the central groove, the presence of local pressure pain, and the prostate fluid can be obtained during the finger examination to do prostate fluid related examination. 2. Prostate fluid examination, about 3-5 drops of prostate fluid can be retained to If the PSA is elevated, the possibility of malignant tumor in the prostate should be considered and further screening is needed. 5.
