How is cancer diagnosed?

If your doctor thinks you might have cancer, he or she will examine you and might order certain tests, including:

  • Blood and urine tests.
  • Imaging tests that allow the doctor to see the inside your body to see if cancer is present (Imaging tests include X-rays, computed tomography (CT) scans, magnetic resonance imaging (MRI), radionuclide scanning and ultrasonography.)
  • Biopsy, a procedure in which the doctor takes a small sample of the tumor and analyzes it under a microscope.
