If a polyp or precancerous growth is found, the gastroenterologist will remove it. Biopsy tissue samples of the intestinal tract, also are taken. If the doctor suspects colon cancer, blood work will be ordered along with a CT scan and a possible barium .
Time comparison between colon scans The remaining one-quarter who preferred CT colonography said they did so because affected not only how clean the colon was but also how accurately polyps and adenomas were detected.

The colon is inflated with CO2, and the physician then scans through Edmundson’s test was negative for colon cancer and he Muldoon ordered a CT scan and confirmed the presence of a mass that needed to be removed. “At the time of surgery I found a four centimeter polyp that was harboring a two centimeter cancer .
