The incidence of prostate cancer in older men is increasing each year, with the most common age group being 75-79 years old, and it is rare to see prostate cancer in people under the age of 50.
Prostate cancer is a relatively inert malignancy that progresses very slowly, but is not found at an early stage unless it is detected by pathology after transurethral resection of the prostate or by physical examination (PSA testing, MRI, etc.).
Because most prostate cancers occur in the peripheral zone of the prostate, a small number of patients may have symptoms of lower urinary tract obstruction (frequency, urgency, difficulty urinating, etc.), and the vast majority of prostate cancer patients have few clinical symptoms in the early stages. It is because prostate cancer does not show tumor-specific symptoms in the early stage, and by the time it becomes symptomatic it is already in the middle to late stage and may have lost the chance of surgery, so regular medical checkups are especially important. men over 45 years old are recommended to have an annual rectal exam and PSA test, and if a relative has prostate cancer, then the risk of prostate cancer increases greatly, in this case it is recommended to have a semi-annual Physical examination. If a hard node is felt on the rectal exam during the physical exam, or if the PSA is elevated, then a prostate puncture biopsy can be considered to clarify the diagnosis.
