The symptoms of prostate disease can vary depending on the specific condition. For prostatitis, symptoms may include pain or discomfort in the pelvic area, frequent urination, and difficulty urinating. For BPH, symptoms may include urinary urgency, weak urine flow, and difficulty starting urination. For prostate cancer, early-stage prostate cancer may not cause any symptoms, but as the cancer progresses, symptoms may include difficulty urinating, blood in the urine, and bone pain.
