Can a CT scan detect colon cancer


Can a CT scan detect colon cancer?
I've been having bad lower abdominal problems along with blood, etc. They said my CT came back ok. Does that mean I can rule out cancer?

No you should do colonoscopy

A CT scan can detect tumours (growths) in the body if they are large enough. Not all tumours are cancer. So a CT scan can identify a tumour, but not whether it is cancer or not. A biopsy would be needed if anything was found in the CT scan. Early colon cancer tumours are often not identifiable by CT scan. There is a non-invasive test called a virtual colonoscopy. But it is not as effective (yet) at detecting colon cancer as the traditional colonoscopy. If you are worried about cancer, talk to the doctor managing your tests and get his/her view on why they are not testing for it or whether it is a planned test if the more likely causes of your problems are ruled out.
