Receiving a call after a screening mammogram is a source of worry for many women. While it’s natural to be concerned, it’s helpful to keep in mind that the vast majority of women who are called back for follow up after a mammogram (more than 9 in 10) are not found to have breast cancer.[1] This is because there are a number of benign conditions that can raise the suspicion of breast cancer when they appear on mammography images. To determine whether a feature found on a mammogram is actually cancer, your doctor will order follow-up testing.
