We are writing to express our concerns with a January 30, 2014 article by Rita F. Redberg and Rebecca Smith-Bindman. The article is alarmingly titled, “We Are Giving Ourselves Cancer”, and is accompanied by a frightening cartoon that appears to be a doctor holding an X-ray film, and wearing a gas mask and helmet. The picture and title are the first clues that sensational claims follow, and the article does not disappoint in that regard, though it falls far short in offering prudent medical advice to frightened patients and parents.
The authors only mention in passing that medical imaging can save lives, and quickly move on to assert that there is little evidence of better health outcomes from current scanning practices. They do not mention, for example that the National Lung Screening Trial recently found that former smokers who received CT screening were 20% less likely to die from lung cancer and 7% less likely to die from any cause, compared to those who were screened with lower dose chest radiography. They do not mention the studies demonstrating the clear clinical benefits of mammography, bone mineral densitometry, and CT colonography. They do not mention the hundreds of studies that suggest that the body’s natural defense systems are quite capable of dealing with very low doses of radiation – like those that have existed on our planet since its beginning and those associated with modern medical imaging.
