Prostate cancer, just like other types of cancer, causes inflammation and swelling of the surrounding tissues, including the bladder and the rectum. Inflammation is a physiologic response made to clear out microorganisms and pathogen molecules. It features a series of changes in the blood vessels and mucosa and ultimately causes pain and other symptoms.
The inflammation in prostate cancer is usually pronounced and sustained over time. It may affect the urethral tissue immediately surrounded by the prostate and even the one that’s not surrounded by it. It also affects the urinary bladder and causes irritation and pain that may aggravate in the event of a urinary infection.
Both prostate cancer and urinary infections may coexist and contribute to the painful or burning sensation while urinating. However, it is essential to have a doctor clearing out the difference after making the appropriate tests along with a complete physical examination.
