Prostatitis has the potential to become cancerous and turn into prostate cancer. Current scientific research has proven that chronic inflammation is very closely related to cancer, and long-term chronic inflammatory stimulation can induce normal cells to initiate the cancerous process. Chronic prostatitis is a common disease among middle-aged and older male patients. Most prostate cancer patients have a history of chronic prostatitis and prostate hyperplasia before the onset of the disease, and because of this, middle-aged and elderly patients with chronic prostatitis and prostate hyperplasia should undergo regular prostate screening, usually by checking the blood prostate-specific antigen or PSA level and prostate ultrasound, to screen out patients with prostatitis who have developed cancer early and treat them early. This is a great way to improve the effectiveness and prolong the survival time of patients.
