ACR Breast MRI Recommendations
According to the American College of Radiology: Women who have greater than 20% lifetime risk (high risk) of breast cancer should get an MRI and a mammogram every year. Women with a 15% to 20% lifetime risk (moderately increased risk) of breast cancer should talk with their doctor about the benefits of adding screening breast MRI to their annual testing. Yearly MRI screening is not recommended for women whose lifetime risk of breast cancer is less than 15%.
Women at high risk include those who:
• Have a known BRCA1 or BRCA2 gene mutation.
• Have a first-degree relative (parent, brother, sister, or child) with a BRCA1 or BRCA2 gene mutation and have not had the genetic test themselves.
• Have a lifetime risk of breast cancer of 20% to 25% or greater, according to a risk assessment tool such as the Gail Model.
• Had radiation therapy to the chest when they were between the ages of 10 and 30 years.
• Have Li-Fraumeni syndrome, Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome, or have one of these syndromes in first-degree relatives.
Women at moderately increased risk include those who:
• Have a lifetime risk of breast cancer of 15% to 20%, according to a risk assessment tool such as the Gail Model.
• Have a personal history of breast cancer, ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS), atypical ductal hyperplasia (ADH), or atypical lobular hyperplasia (ALH)
• Have extremely dense breasts or unevenly dense breast tissue when viewed by mammograms.
If MRI is used, it should be in addition to a screening mammogram. This is because although MRI is a more sensitive test, it may still miss some cancers that a mammogram would detect.
