Does Bowel Cancer Show Up On A Urine Test
What would experts say? Could a full body ultrasound scan show previously undiagnosed bowel cancer?
No: Ultrasound is not a good way to look at the bowel/intestines. There is a lot of artifact from the gas within the bowel that makes things inside the bowel difficult to see. A test for blood in the stool and/or colonoscopy would be better. Sometimes a ct scan or upper GI or barium enema can also help. ...Read more

Sometimes: I'm not sure what a "ct tap" is. I assume it's a typo for "ct scan". A ct scan of the abdomen and pelvis can sometimes show bowel cancer, but often they can be difficult to detect, particularly in the large bowel (though this is improved with dedicated ct colonography, which increases detection of colon cancers though may not find other diseases as well as a standard ct). ...Read more

Could anyone explain what bear print in eyes is linked to bowel cancer been told I have over 3 spots in both eyes and need tests why?
Bear prints?: Freckles on the retina (congenital hypertrophy of the retinal pigment epithelium) were discovered to be a marker for gardner's, a variant of familial polyposis of the colon (fap).

Autopsy studies show that 1.7% of average-risk people in 20s have an adenoma, so why don't they recommend screening for bowel cancer before age 50?
No value: The only value in removing polyps is the rare one that has genetic changes to become cancer. About 90% don't progress. Survival hasn't changed with long history of polypectomy. In those that do change it takes years for the transformation and for the other lesions, they don't show up as a bowel malignancy until one is usually in their 50's. ...Read more
Is there any imaging test to detect colon cancer that doesn't require bowel prep? I'm symptomatic but can't do bowel prep due to heart & electrolytes
Colin ca test: You state that you are 20 years young! Whoever suggested to you that you get a colonoscopy at your age? Unless you have an inherited polyposis syndrome or some other rare disorder you would not have that done so early. If U have blood in stool it is most likely due to hemorrhoid, not to cancer. ...Read more
Is it normal for 27 yr old f to have diverticular disease? CT shows several diverticular and remarkably thickened bowel. Could it also be colon Cancer
Could be : Diverticular disease is seen in older patients ie over 60, but I have seen it in younger people. One of the theories on why people get diverticuli, or tiny pouches, in the colon, is the low fiber, high fat diet in the U.S. There may also be an inherited aspect.Thickened wall of the colon and diverticuli aren't associated with cancer, but it's reasonable to get a colonoscopy--talk to your doctor. ...Read more
Pain and elevated liver. Doctor thought I could have gallstones. Got an ultrasound. Can an ultrasound show anything else (such as bowel cancer)?
It has limitations: Ultrasound is a very good tool in diagnosing gallstones and evaluate the liver. However it is not a good tool to evaluate the colon. Usually ultrasound does not show colon cancer unless the colon cancer is very large. The best way to diagnose colon cancer is colonoscopy. ...Read more

The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet). This empties into the colon or large intestine (about 5 feet), which then becomes the sigmoid colon, rectum and out the anus. So, every morsel eaten ...Read more
