PSA, what is it? Almost every time I sit in the clinic, someone will come with a lab test or physical examination report and ask about PSA! The PSA is the most important thing in the world. The PSA is a protein produced by the epithelial cells of the prostate gland, which has a protective effect on the activity of sperm. The actual PSA is a good way to get the most out of your life. Under normal circumstances, PSA is excreted with the semen and does not enter the bloodstream directly. The PSA can be used as an indicator of the health of the prostate because it is almost impossible to measure PSA in the blood when the prostate is healthy! In turn, it just means that there is something wrong with the prostate before it is detected in the blood!!! This is true, PSA is produced by the epithelial cells within the prostate and enters the bloodstream when tumor cell growth or other factors such as extrusion destroy or damage these structures. Based on extensive statistical analysis, the internationally accepted standard for a normal PSA is 4 ng/mL. This indicator rises significantly when there is a tumor, and often PSA can be used as one of the important tools for early screening of prostate cancer. To further illustrate: the male prostate is a whole egg, put this egg in a large wrist full of water, if this egg is good, then the water in this bowl is also clean; if the shell of this egg is broken, then the water in this bowl will have something of egg white or egg yolk; this something of egg yolk or egg white is equivalent to PSA. So is it true that if the PSA is high, you must have The most important thing is that you have a high PSA and you have prostate cancer? Obviously, this is not the case. This is a feature of medicine, and the discovery of an elevated PSA will prompt the doctor to perform further tests, such as ultrasound, MRI, and puncture biopsy. And why is this? The reason for this is that there are other factors that can contribute to an increased PSA: the effects of diet and medication, some frictional effects acting on the prostate (such as sedentary, cycling), excessive forceful prostate massage, severe constipation, etc. The PSA can be increased, but it is not necessary to be nervous, through the review, regular follow-up, if it continues to increase, combined with ultrasound and other comprehensive examination, you can get an early diagnosis of prostate cancer.
