You do NOT want an unnecessary scan. There is a common misconception that knowledge in this arena is good. While the scan itself is not dangerous, what you would be required to do with the information is. Almost everyone has some abnormalities, we call them “incidentalomas”. Knowing about them will cause unneeded biopsies and months to years of worry that “you have cancer” or " something is not right". There is a reason that there are strict screening recommendations in medicine. Unless a disease has a long preclinical (pre-symptom) phase with a clear improvement in outcomes from early treatment ( no lead time bias) then screening ( testing without symptoms to make sure nothing is there) is openly harmful and should not be done.
