Diagnostic Procedures for Cancer

What are diagnostic procedures for cancer?

When symptoms suggest cancer, your physician may request/perform any of the following procedures to help positively diagnose it:

  • a detailed medical history -- family and personal


  • thorough physical examination


  • pelvic examination of the uterus, vagina, ovaries, bladder, and rectum


  • Pap test may be requested at the time of pelvic examination
  • Other diagnostic procedures that may be requested include:

  • imaging tests, such as:


    • x-ray - diagnostic tests that use invisible electromagnetic energy beams to produce images of internal tissues, bones and organs on film. X-Rays may be taken of any part of the body to detect a tumor (or cancer).


    • CT or CAT (computed tomography) - a non-invasive procedure that takes cross-sectional images of the brain or other internal organs; to detect any abnormalities that may not show up on an ordinary x-ray. The CT scan may indicate enlarged lymph nodes -- a possible sign of a spreading cancer or of an infection.


    • radionuclide scan - an imaging scan in which a small amount of radioactive substance is injected into the vein. A machine measures levels of radioactivity in certain organs, thereby detecting any abnormal areas or tumors.


    • ultrasound - an imaging technique that uses sound waves to produce an image on a monitor of the abdominal organs, such as the uterus, liver, and kidneys.


    • MRI (magnetic resonance imaging)- a non-invasive procedure that produces two-dimensional view of an internal organ or structure, especially the brain and spinal cord. The MRI may show abnormal nodules in bones or lymph nodes -- a sign that cancer may be spreading.
  • endoscopy - use of a very flexible tube with a lens or camera (and a light on the end), which is connected to a computer screen, allowing the physician to see inside the hollow organs, such as the uterus. Biopsy samples can be taken through the tube.


  • laboratory tests to examine any/all of the following:


    • blood
    • urine
    • other fluids
    • tumor tissue
  • biopsy to remove a sample of the suspicious tissue for examination in a laboratory by a pathologist


  • Once the cancer is diagnosed, an evaluation will be made to determine the extent (stage) of the cancer.
