Doctors diagnosed more cases of an invasive form of breast cancer using magnetic resonance imaging than with standard mammography technique, according to a study published in The Lancet today.
Researchers at the University of Bonn in Germany found that out of 167 women diagnosed with ductal carcinoma in situ, often a precursor to invasive breast cancer, 92 percent were diagnosed using MRI scans, while only 56 percent were found using mammography, the diagnostic standard.
These findings suggest that MRI could improve the ability of doctors to catch the condition, which is found in 60,000 women in the U.S. each year, according to the American Cancer Society. Previous studies dismissed MRI screenings as not sensitive enough to find pre-cancer. Mammography detects about 20 percent of early, non-invasive breast cancers, the researchers said.
