Procedures: The largest study to compare the new test to traditional colonoscopies found the latest method as accurate and perhaps even more so, indicating it would provide a powerful tool to reduce the number of people affected by the common malignancy. Colon cancer strikes an estimated 105,500 Americans each year and kills more that 57,000, making it the second leading cancer killer after lung cancer. If detected early, it is highly curable. As a result, physicians recommend regular colonoscopies. Due to the uncomfortable nature, many people avoid the procedure. It involves snaking a long tube with a small camera attached to the end into the colon to look for polyps, which can become cancerous. Only about 37% of colon cancers are diagnosed before they have progressed. The virtual colonoscopy allows people to avoid having the physical exam. People undergoing both procedures still have to go through the unpleasant task of purging their digestive systems the night before, but the virtual test requires no anesthesia or sedation. That generally means they don’t need a driver or to take time off of work. A virtual colonoscopy involves a CT scan of the abdominal area. CT, which stands for computed tomography, uses special x-ray equipment to obtain a series of cross-sectional pictures of the inside of the body from different angles. A computer program assembles the images into what essentially looks like a film moving through the entire length of the colon. Doctors can watch
the images on a computer screen, looking for signs of a polyp. If they
find one, the individual would immediately be referred for a standard
colonoscopy and possibly a biopsy. |
