I had two ct scans done recently. one without contrast and one with contrast. both came back normal. what are the chances of a tumor being missed?

CT: That would depend on what type of tumor you are looking for. The CT would not miss gross tumor. For example it does not miss colon cancer, but it will miss early polyps.
