Dear chayahindy: Mammogram remains the standard of care in screening for breast cancer in women of average risk. Currently, the role of MRI as a screening tool in women who are at high risk for developing breast cancer is evolving. MRI may be better at detecting certain types of abnormalities earlier but is not a test to be used in isolation. Although it can be helpful in the preoperative evaluation of breast cancer, it is generally not considered a mandatory part of diagnostic imaging. The risk for a contrast reaction in the future may be reduced with steroid premedication, but for your case the risk of the test must be weighed against the potential benefit. A breast specialist would be best suited to review your personal risk and make recommendations for followup - including whether or not an MRI is necessary and/or could be safely done in the future.
