If the prostate is simple and not accompanied by uncomfortable symptoms, it usually does not matter; if the prostate is slightly enlarged due to prostatitis, prostate cancer, etc., it is important. The normal prostate gland has a transverse diameter of about 4cm, a vertical diameter of about 3cm, and an anterior-posterior diameter of about 2cm, and the volume of the prostate gland increases with age, with faster growth in childhood and old age, and relatively static growth in youth. Therefore, if the prostate gland is slightly enlarged in a simple case and is not accompanied by uncomfortable symptoms, it usually does not matter and there is no need to worry too much. If the prostate is slightly enlarged due to prostatitis, prostate cancer, prostate hyperplasia and other diseases, it is usually important. If the prostate gland is in a diseased state and the patient does not actively cooperate with the doctor’s treatment, it will easily lead to aggravation of the condition, affect the health of the body, and even lead to atrophy of the prostate gland and loss of function. It is recommended that people with slightly enlarged prostate do further detailed examination to check whether it is caused by diseases, and if it is caused by diseases, it should be treated in time. Pay attention to personal hygiene, avoid unclean sex, try to wear cotton, loose underwear.
