Breast cancer in pregnant women accounts for 3% of all breast cancers. Mammography is performed in pregnant women for diagnostic purposes only, usually in settings where a sonographic examination is unable to sufficiently clarify physical findings. A mammogram comprising 4 views that is done with abdominal shielding exposes the fetus to 0.4 rads. As fetal exposure to radiation is concerning, especially during the first few weeks of gestation, routine screening mammograms are not performed during pregnancy.
