Breast Cancer Screening: Why You May Need More Than a Mammogram

For women at average risk of developing breast cancer, having an annual screening mammogram after age 40 can help detect breast cancer in its earliest stages — when treatment is often most successful.

But for women at higher risk of developing breast cancer, an annual mammogram may not be enough.

Mammography and Breast MRI

According to the American Cancer Society, women with a family history of breast cancer or genetic mutations that increase cancer risk should have a screening mammogram and a breast MRI every year starting at age 30. Your doctor may also recommend a breast MRI if you have dense breasts.

Breast MRI uses magnetic fields and radio waves to create detailed images of breast tissue. During the test, you will receive an injection of contrast dye through an IV. The contrast dye will highlight any abnormal areas of breast tissue.

Although breast MRI is a highly sensitive test, it isn’t a replacement for your annual mammogram. An annual mammogram combined with a breast MRI provides the best chance of early cancer detection.

Breast Ultrasound

If you have dense breast tissue, your doctor may recommend a breast ultrasound in addition to an annual mammogram — especially if you are unable to have a breast MRI. Ultrasound technology uses sound waves instead of radiation to create images of breast tissue.
