Prostate cancer is a type of cancer that occurs in the prostate, a small gland located below the bladder in men. This gland is responsible for producing seminal fluid, which nourishes and transports sperm. Prostate cancer usually grows slowly and may not cause significant health issues for many years. However, in some cases, it can be aggressive and spread to other parts of the body. Symptoms of prostate cancer can include difficulty urinating, blood in urine, and pain in the lower back or hips. Regular check-ups and screenings, such as the PSA test, can help detect prostate cancer early, increasing the chances of successful treatment.
