HealthyAnswers.com cites findings from a recent U.S. government-funded study done by Emory University [Exposure to Low-Dose Ionizing Radiation from Medical Imaging Procedures, New England Journal of Medicine, August 2009], that people are being exposed to unnecessary radiation through too-frequent medical imaging tests. As a result, their risk of cancer is increasing. For example, the Yale School of Public Health recently reported [Non-Cancerous Brain Tumors Linked to Frequent Dental X-Rays] a higher risk of a certain type of brain tumor, meningioma, in people who get yearly bitewing dental x-rays. Womens groups have also expressed concern that statistics show a womans risk of cancer increases as she gets older. Despite that, mammograms are recommended yearly for women over age 50, even with no family history of breast cancer.
Additionally, HealthyAnswers.com relates, earlier studies from 2007 cite that 2% of all cancers directly arise from CT scanning alone. HealthyAnswers.com states that the commonly used nuclear imaging tests, like CT and PET scans, carry the highest exposure to radiation.
Mark Rosenberg, M.D., one of HealthyAnswers.coms medical experts, explains about radiation exposure from medical imaging: Radiation exposure occurs naturally in everyones daily routine from sun and soil exposure, overhead electrical wires, and even just traveling coast-to-coast on an airplane about 3 mSv (milliseverts) a day, a moderate amount. One nuclear stress scan, though, typically used to follow the progression of heart disease, contains about 15 mSv of radiation 5 times the amount of typical everyday exposure. Adding CT scans, or x-rays, to follow healing of a fracture, or repetitive chest x-rays to follow healing of an upper respiratory condition, can add extra toxin overload from radiation. And, except for mammograms, there are no federal guidelines currently in place for radiation exposure from medical imaging studies. Many doctors like to make use of their facilities most modern technologies but they may also carry more radiation risk. People should ask their doctor how much mSv a test contains and if there is an alternative to the test.
