- The use of advanced diagnostic imaging in the US has substantially increased between 1996 and 2010. The use of CT scans tripled during that time, dramatically increasing lifetime radiation exposure as CT scans and nuclear medicine examinations deliver far higher doses of radiation than conventional x-rays. Researchers warn there’s evidence showing that radiation levels in the range now employed are linked to the development of radiation-induced cancers
- Girls who receive radiation to the chest to treat childhood cancer have a high risk of developing breast cancer at a young age, according to recent research. Even those who received low doses of the common cancer treatment face an increased risk of breast cancer later, the scientists said, adding that the risk posed by radiation may be as great as having the BRCA1 or BRCA2 mutation—two genetic mutations associated with an increased risk of breast cancer
- CT scans are also associated with an increased risk of cancer. A child who is exposed to the radiation from just two or three scans will triple their risk of developing brain cancer later in life. Five to 10 scans may also triple the risk of leukemia
