Ive had 5 ct scans between the years 2008-2014 for various health reasons. i might need another one. the radiation concerns me. is this too much?

Sounds ok, but: Although very rare, one cannot know if she will be the unlucky one to get cancer from CT's. She may never get cancer despite many CT's, or she may get cancer unrelated to the CT's. One must live life in a relaxed manner and not worry about all the possible things that can happen to unlucky people. She should ask if other imaging can be done instead of x-ray or CT but there may not be a substitute.
