CT scans give more radiation by between 1000 to 5000 times as x-rays. So, if you go in and out of the CT scanner 4 times that's like 4000 to 20,000 x-rays. So, basically you have to spend the rest of your life wondering what may develop. Unbelievable! For me, it seems doctors just gamble with people's future health for it being easier and quicker for them. It seems like a win-win for the doctors.
