Sometimes cancers or polyps bleed. An FOBT checks for blood in your stool. It's a highly sensitive test, which means it can find polyps and cancer. However, sometimes the test can indicate that there's a polyp or cancer when there isn't. This is called a false positive. Or it can miss a polyp that doesn't bleed. Therefore it's commonly used as an initial test before another screening test such as a colonoscopy or a sigmoidoscopy.

|
|
Detailed information on chest x-rays, including reasons for the procedure X-rays are made by using low levels of external radiation to produce images of the body, the organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially treated plates (similar to camera film) and a "negative" type picture is made. The more solid a structure is, the whiter it appears on the film. For this reason, bones appear very white on an x-ray film, but less dense tissue such as muscle, blood, skin, and fat appears darker.
