We Are Giving Ourselves Cancer

By RITA F. REDBERG and REBECCA SMITH-BINDMANJAN. 30, 2014

"DESPITE great strides in prevention and treatment, cancer rates remain stubbornly high and may soon surpass heart disease as the leading cause of death in the United States. Increasingly, we and many other experts believe that an important culprit may be our own medical practices: We are silently irradiating ourselves to death.

The use of medical imaging with high-dose radiation — CT scans in particular — has soared in the last 20 years. Our resulting exposure to medical radiation has increased more than sixfold between the 1980s and 2006, according to the National Council on Radiation Protection & Measurements. The radiation doses of CT scans (a series of X-ray images from multiple angles) are 100 to 1,000 times higher than conventional X-rays.

Of course, early diagnosis thanks to medical imaging can be lifesaving. But there is distressingly little evidence of better health outcomes associated with the current high rate of scans. There is, however, evidence of its harms.

The relationship between radiation and the development of cancer is well understood: A single CT scan exposes a patient to the amount of radiation that epidemiologic evidence shows can be cancer-causing. The risks have been demonstrated directly in two large clinical studies in Britain and Australia. In the British study, children exposed to multiple CT scans were found to be three times more likely to develop leukemia and brain cancer. In a 2011 report sponsored by Susan G. Komen, the Institute of Medicine concluded that radiation from medical imaging, and hormone therapy, the use of which has substantially declined in the last decade, were the leading environmental causes of breast cancer, and advised that women reduce their exposure to unnecessary CT scans.

CTs, once rare, are now routine. One in 10 Americans undergo a CT scan every year, and many of them get more than one"...

Share your feedback on the campaign
Choosing Wisely® aims to promote conversations between physicians and patients by helping patients choose care that is:

Supported by evidence
Not duplicative of other tests or procedures already received
Free from harm
Truly necessary
In response to this challenge, national organizations representing medical specialists have been asked to “choose wisely” by identifying five tests or procedures commonly used in their field, whose necessity should be questioned and discussed. The resulting lists of “Five Things Physicians and Patients Should Question” will spark discussion about the need—or lack thereof—for many frequently ordered tests or treatments.

This concept was originally conceived and piloted by the National Physicians Alliance, which, through an ABIM Foundation Putting the Charter into Practice grant, created a set of three lists of specific steps physicians in internal medicine, family medicine and pediatrics could take in their practices to promote the more effective use of health care resources. These lists were first published in Archives of Internal Medicine. "...
