  • Rationale and Comments

    Whole-body scanning with a variety of techniques (magnetic resonance imaging, single-photon emission computed tomography, positron emission tomography, CT) is marketed by some to screen for a wide range of undiagnosed cancers. However, there are no data suggesting that these imaging studies will improve survival or improve the likelihood of finding a tumor (estimated tumor detection is less than 2% in asymptomatic patients screened). Whole-body scanning has a risk of false-positive findings that can result in unnecessary testing and procedures with additional risks, including considerable exposure to radiation with positron emission tomography and CT, a very small increase in the possibility of developing cancer later in life, and accruing additional medical costs as a result of these procedures. Whole-body scanning is not recommended by medical professional societies for individuals without symptoms, nor is it a routinely practiced screening procedure in healthy populations.
