While breast MRI can find cancers that mammograms miss, researchers are not ready to name the test the new "gold standard" for breast cancer detection.
Researchers from Fred Hutchinson Cancer Research Center worked with colleagues to create new guidelines that make sure the test is used responsibly. They say MRI is not a substitute for mammograms or breast ultrasounds, rather it should be a supplement to those screening tools. Among women who have been diagnosed with the disease, MRI can enhance detection of cancerous areas, including those in the other breast. Finally, experts say surgical decisions should not based on MRI because some suspicious spots may not be cancer.
