It's a startling trend: Many women with cancer in one breast are choosing to have their healthy breast removed, too.
But a study being presented later this week says more than three-quarters of women who opt for double mastectomies are not getting any benefit because their risk of cancer developing in the healthy breast is no greater than in women without cancer.
The endless debate over routine mammograms is getting another kick from an analysis that sharply questions whether the test really does what it's supposed to.
Dr. H. Gilbert Welch, coauthor of the analysis of mammography's impact, which was just published in The New England Journal of Medicine, tell Shots that the aim was to "get down to a very basic question."
Researchers report that women with genetic mutations that put them at dramatically increased risk of developing breast cancer may also face a heightened risk from radiation used during medical screening and diagnosis.
The imaging tools that help doctors identify disease, injury or damage to the body have long been known to carry some risk of cancer, in large part because ionizing radiation can damage the genetic material in the body.
