Analyzing individual breast tissue for specific structural characteristics may more precisely determine a woman's risk for developing breast cancer.
In the Oct. 5 online issue of the Journal of Clinical Oncology, researchers report that the more acini a woman has -- these are the sacs that produce milk -- and the larger her breast lobules, the higher the chance she will get breast cancer.
"A tremendous number of women get breast biopsies from abnormal mammograms. They number 1 to 2 million people a year in the U.S. alone," said study co-author Derek Radisky, an assistant professor of biochemistry at the Mayo Clinic in Jacksonville, Fla.
