Cancer Treatment

Preliminary diagnosis identifies a suspicious mass or other change in the body that requires further investigation. Some symptoms must be evaluated with special X rays and other advanced imaging techniques. One X-ray technique, called computed tomography or CT scan, can reveal suspicious masses in such internal organs as the brain and the lungs. A technique called magnetic resonance imaging (MRI) uses magnetic fields and radio waves to produce images of internal organs. These imaging techniques allow physicians to determine the exact location, size, and shape of cancer tumors and determine whether the cancer has spread.
