How much medical imaging is too much? ive had 2 ct scans and 5 mammograms and a few dental x-rays 3 x-rays all of abdomen im very scared about getting cancer from this. what are my chances?

That is not much: It is highly unlikely that a patient develops cancer from just having 2 or 3 CT scans. Life in the modern world causes cancer (and of course there was cancer before modern times), but having 3 CT scans will make no noticeable difference when compared to everything else we face in life. In California, we have "useless" signs posted everywhere, warning about cancer-causing substances.
