Prostate cancer is a type of cancer that develops in the prostate gland, which is a small gland that produces seminal fluid in men. The exact cause of prostate cancer is unknown, but potential risk factors include age, family history of prostate cancer, obesity, and exposure to certain chemicals. Early stage prostate cancer may not cause any symptoms, but as the cancer progresses, symptoms may include difficulty urinating, blood in the urine or semen, pain in the back, hips, or pelvis, and erectile dysfunction. Diagnosis is typically made through a combination of physical examination, blood tests, and biopsy, and treatment may involve surgery, radiation therapy, chemotherapy, and hormone therapy, depending on the stage and characteristics of the cancer.
