Prostate cancer symptoms are caused by tumors pressing on healthy tissue. This can cause problems with urination and pain. Early prostate cancer and small tumors usually do not cause symptoms. The cancer may not cause symptoms until it is late stage.

If you experience any symptoms, do not assume it is due to cancer. Some of these symptoms can be caused by other less serious conditions, such as benign prostatic hyperplasia (BPH) or an infection. It is still important to discuss them with your doctor. Early detection and treatment improve outcomes for cancer.
