The prostate is a gland that is part of the male reproductive system located near the bladder. Diseases of the prostate include prostatitis, an enlarged prostate, and prostate cancer. Prostate cancer is one of the most common cancers in men. Symptoms of prostate issues include frequent and painful urination, blood in the urine or semen, and painful ejaculation. Diagnosis involves tests like a PSA test, biopsy, and digital rectal exam. Treatments range from medication to surgery, with the goal of preventing complications like cancer spreading, incontinence, and erectile dysfunction. Maintaining a healthy lifestyle and diet can help reduce risks.
