Use of medical imaging has surged in the past decade, and now a new
study suggests the trend carries a risk: Having multiple cardiac and
chest CT scans may increase the chances of breast cancer, researchers
report.
The risk appears higher for younger women, the preliminary research showed. For example, for a girl or young woman under age 23 who has two
high-dose cardiac or chest CT scans, the risk of developing breast
cancer in the next 10 years doubles, the researchers found.
The study, scheduled for presentation Tuesday, November 27, 2012, at the Radiology Society
of North America annual meeting in Chicago, included data on radiation
exposure from the Group Health insurance database. The researchers
reviewed CT scan-dose data on more than 1,600 females between 2000 and
2010, and used a statistical modeling technique to estimate the average
radiation doses they received.
