Millions of us are walking around with innocent imperfections in our internal organs. In other words, if any of us were to undergo a CAT scan, many of us would have abnormalities described by vigilant radiologists.
Sure, some folks have been saved by having cancers discovered early. If I or a family member were one of them, I might have a different view of this issue than I do now. However, these occasional accidental rescues must be balanced against the enormous financial expenditures, anxiety costs, radiation exposures and direct harm from medical complications that result from these medical cascades. I am convinced that the harm outweighs the good.
So, when your doctor recommends a CAT scan, you may feel that there is no risk from a non-invasive study. Think again. The CAT scan may be the match that lights the fuse.
