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
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
For what length of time do orallly administered treatments of bowel cancer take to show they are working?
Talk to your doctor: You have bowel cancer and have been given an oral medication to help. Talk to your doctor and discuss what time it should take for the effect to be noticed. It is always important to talk to your doctor before you leave the office and understand what the expectations of any new medication. Also talk to your pharmacist to see if any interaction exists between a new and old medication. ...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
Colon Cancer: CEA is blood test associated w/colon Ca. However, not a good screening test - significant false +, can be high with benign conditions & in early Colon Ca CEA may not be elevated. Current gold standard for Colon Ca screening is colonoscopy. 2 other alternatives- virtual colonoscopy (CT) & a new stool DNA test just recently approved by FDA. Screen age 50, 40 if + family history Colon Ca or polyps ...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). You're an adult and without a personal or family history, you may simply wish to be screened for colon cancer more often than other folks. ...Read more
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
Worried I might have colon cancer due to change of bowel habbit. My habbit return to normal for a few weeks then go of cycle then return back to normal. Never a persistent change. Been diagnosed with ibs after full blood test came back clear?
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

Would bowel cancer alter blood tests? Abdo pain, rectal bleeding and back ache for 12 mnths. Dr won't refer for colonoscopy as I'm 27 + blood test ok
See different doctor:
Rectal bleeding warrants investigation. It is unlikely that you have colon cancer and colonoscopy is probably not required, however, you still need to be evaluated for the cause of rectal bleeding. It may be hemorrhoids, even that needs to be treated. If your current doctor is providing satisfactory care, it is reasonable to see another doctor.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

I'm 23 yr old having stomach pain, gas, inflammation, and bowel problems. My grandmother had colon cancer. Can I test for cancer this early?
Probably not...: At 23, you should pay attention to what and how to eat a healthy foods such as those with less sugar, fat, and salt, with more vegetables and fruits, with less junky foods, with more nuts, beans, etc. Besides more exercise, better sleep, and no overindulgence and obsession for everything we do in life, will help live a long happy life. As to concern for family history of colon cancer, ask doctor. ...Read more
Would advanced colon cancer show up on a CT scan of my abdomen? Reg CT scan not virtual colonoscopy.
Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read more
If colon cancer was causing pain RUQ wouldn't it be big enough to show on CT of abdomen and pelvis? 31 yo- fecal occult blood negative
Not likely colon Ca:
Classic colon cancer causes pain via colon obstruction, so in that case, CT would see it. But this would not be expected in a 31 yo w/ occult neg stool.
RUQ pain can be any number of causes in young adult. Need to know more history and clinical exam by a Dr. To advise work up.
Best screen for colon Ca is colonoscopy, but unless strong family history, may start around 50 yrs old. ...Read more

Colon Cancer: There is no direct evidence linking bacterial growth with colon cancer; risk factors traditionally include lack of fiber intake, high fat content in the diet, certain hereditary conditions and family history of the diseases. Some evidence suggests Aspirin can also reduce the risk of colon cancer. Ulcerative colitis and crohn's disease impart an increased risk of cancer. ...Read more
Best to abstain.: These types of questions are always hard to answer: on the one hand, you are asking a physician to endorse the use of a known toxin associated with increased risks of colon cancer as well as many other diseases; on the other hand, one drink on an occasional basis will probably have no detrimental effect. Like any vice, I would like to say "no", but realistically can say "in moderation". ...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
