Can. But not always. Colonoscopy best.
Yes, when it is big. It can be shown up in a ct scan when the size is large enough and by then the chance is probably it is already giving you symptoms like abdominal pain/cramping , change in bowel movement, etc. Small polyps or small tumor in colon would not be able to be picked up on ct scan and colonosocpy is the best modality to screen for colon cancer.
I am required to have a pelvic CT scan once a year as follow-up to colorectal cancer treatment. Are double scans without and one with contrast needed?
Scared I've colorectal cancer. Had recent abd x-ray, abd CT w/ contrast, and ab ultrasound. Do these rule out the possibility of late stage cancer?
Yes. However, they do not rule out the possibility of early colon cancer. Colonoscopy is the standard test done for early detection of colon cancer and is recommended for patients with family history of colon cancer even at younger ages (less than 50). Is there any reason you are specifically scared of having colorectal cancer? Talk to your doc about your fears as well as symptoms. Read more...
What stage of colorectal cancer would a normal ABD CT rule out? If I had colorectal cancer w/ a normal CT does that mean only early stage is possible
CT scans NOT diagno. CT scans of the abdomen, no matter how "well" they are performed, are NOT diagnostic of colon cancer. Only a (colonoscopic) biopsy & (surgical) staging can do that. Thus, your question is a non-starter... colorectal cancer cannot be "ruled out" from a CT scan; while CT scan can help plan a staging procedure (& a normal CT scan is reassuring), only an oncologist can stage cancer if it exists.
