Can An Abdominal Pelvic Cat Scan Screen For Colon Cancer Or See A Mass In The Rectum
Sometimes: Sometimes a cat scan will be able to see a mass in the colon or rectum but it is not a good test for screening for colorectal cancer. There is a specialized type of ct scan that creates a virtual image of the inside of the colon that is sometimes used when a patient is not a good candidate for a colonoscopy. ...Read moreSee 2 more doctor answers
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
CT Scan Findings: Ct scan is not the best study to detect colon cancer or ulcers. Although a ct scan may show a large sized colon cancer, the sensitivity of this is greatly reduced without the administration of oral contrast. Ulcers are typically not seen on ct scan. The best diagnostic study for both of these would be an endoscopy and colonoscopy. ...Read moreSee 1 more doctor answer
On chemo for metastic colon cancer . Ct scan coming up - says Neck, thorax , abdomen and pelvis . Is neck usually scanned ?
Yes: There are multiple sites where metastatic colon cancer can appear. While the liver and lung are the most common visceral sites other than lymph nodes in abdomen , spread can occur to the left supraclavicular fossa. Troisier sign is the finding of a hard and enlarged left supraclavicular neck node (Virchow's node). It is a sign of metastatic abdominal malignancy draining the thoracic duct. ...Read moreSee 1 more doctor answer
It can sometimes: Unfortunately, ct scans are not very good at finding small polyps like a colonoscopy does. The scan will usually only pick up larger lesions. The endoscopy has an additional benefit of allowing small polyps to be biopsied or removed. Polyps tend to grow to become cancer, so they should be removed if possible. Ct scan, won't allow treatment at same time, and thus, is not as good a test for colon ca. ...Read moreSee 1 more doctor answer
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

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 moreSee 3 more doctor answers
A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?
No, but...: But very suspicious for colon cancer. If your friend is similar in age to yourself a mass in the colon on ct scan is cancer until proven otherwise. And cea levels can go up for other reasons but, given the mass, they would strongly favor cancer. But to answer your question "no"... They are not definitive. You would need a piece of the mass under a microscope to prove definitively its cancer. ...Read moreSee 1 more doctor answer
Chance 4 ab / pelvic CT scans all missed symptomatic colon cancer (narrow stools, occaision blood) over three years. Also had sigmoidosopy to 35cm?
Sometimes: Ct colography is never meant to replace a colonoscopy. At high volumn centers, the detection sensitivity of ct exam is indeed comparable to colonoscopy but you need to know the rate of detection of your imaging facility. Bowel prep is required for both procedures - no way around the unpleasant process. Beware that there is significant radiation exposure with the exam. ...Read moreSee 4 more doctor answers

Not Designed for it: Not what a ct scan is designed to do. Usually colon cancer will not be clearly evident on ct until it is at stage iii or stage IV level, since it has to anatomically change the colon to be evident on ct. To get that level of change, it needs to be at minimum a locally advanced tumor. Every once in a while it may be evident at the stage ii point, but very low sensitivity. ...Read moreSee 1 more doctor answer
Would a cat scan a month ago show advanced colon cancer? Been having weakness weight loss last few weeks and i hear you don't get symptoms till advnc
Depends: It depends on what you mean by advanced. If you mean spread to other organs, usually it will. If you mean advanced within the colon itself. Not unless it was really large. I've noticed that you seem to be asking a lot about colon cancer. If you have had a clear colonsocopy, you should be in the clear. ...Read moreSee 1 more doctor answer
