'CT (computed tomography) scans are now a well established medical imaging procedure which both the government and the scientific community have confirmed increases cancer risk.
CT scanners bombard the human body with radiation levels more than 1000 times greater than a standard x-ray. They damage DNA and create mutations that spur cells to grow into tumors.
Currently, more than 80 million CT scans are performed annually in the United States, around half in women, reflecting the large number of individuals who are exposed to this source of radiation.
Thought leaders in radiology are often quoted as estimating that 30% or more of advanced imaging tests may be unnecessary, and while there are few scientific data to precisely estimate the amount of overuse, many radiologists believe the proportion may be even higher.'
