Are There Any Tests That Are Better Than a Mammogram for Dense Breasts?
In dense breasts, cancer can be hard to see on a mammogram. Magnetic resonance imaging (MRI) and to a lesser extent, ultrasound can find breast cancers that can't be seen on a mammogram. However, MRI and ultrasound show findings that are not cancer, which can result in added testing and unnecessary biopsies. Also, the cost of ultrasound and MRI may not be covered by insurance.
