Fecal Occult Blood Test (FOBT)
A fecal occult blood test checks for hidden blood in three consecutive stool samples. One clinical trial in the United States reported a 33 percent reduction in colorectal cancer deaths and a 20 percent reduction in colorectal cancer incidence among people offered an annual FOBT. Population-based trials in Europe have demonstrated that screening every other year reduced colorectal cancer deaths by 15 to 18 percent.
During a sigmoidoscopy, the doctor checks inside the rectum and lower (sigmoid) colon with a lighted tube called a sigmoidoscope. If polyps are found, the doctor removes them. The procedure to remove polyps is called a polypectomy.
During a colonoscopy for rectal cancer screening, the doctor examines inside the rectum and entire colon using a long, lighted tube called a colonoscope. The doctor removes any polyps that may be found.
Barium Enema
A barium enema is a test that involves a series of x-rays of the colon and rectum. The patient is given an enema containing a barium solution, and air is pumped into the rectum. The barium and air outline the colon and rectum on the x-rays.
