Early-stage (low-risk) prostate cancer rarely causes any signs or symptoms. If cancer cells are only found in your prostate, it can take many years before a prostate tumour (cancerous growth) can get big enough to cause symptoms or for doctors to find it. Even for advanced stages of prostate cancer, there might be no symptoms showing. However, if you do have concerns, you should see your doctor. The symptoms listed here can also be due to non-cancerous conditions such as Benign Prostatic Hyperplasia (BPH).
