Study: Scatter radiation from mammograms does not increase cancer risk

November 27, 2012

Doses of scatter radiation received from mammograms are low and do not result in an increased risk of cancer, according to research being presented by Alison Chetlen at the annual meeting of the Radiological Society of North America.

Chetlen, an assistant professor of radiology at Penn State College of Medicine, said the results of her research suggest that the use of a thyroid shield during mammography is not needed.

Chetlen and her team measured the dose of radiation received by areas around the breast: the thyroid gland, salivary gland, sternum, uterus and the lens of the eye. Doses measured were low to negligible.
