How do I know if I have prostate cancer?

Prostate cancer in its early stages usually has no symptoms, so the only way to detect it early is through medical check-ups. The main tests are the PSA blood test and digital rectal examination. In advanced stages, symptoms such as difficulty urinating, increased urinary frequency, blood in the urine or bone pain may appear. If you are over 50 years of age, or if you have a family history, it is advisable to see a urologist even if you do not have any discomfort.
