Recommended Timing between COVID-19 Vaccination and Mammography

The Society of Breast Imaging is recommending women schedule their annual screening mammogram prior to getting the first dose of the COVID-19 vaccine or 4-6 weeks after the second dose.

A mammogram at that time might falsely interpret this swelling as a potential sign of breast cancer and the patient would be called back for unnecessary additional evaluation

This timing interval does not apply to scheduling diagnostic mammograms for breast symptoms. Those should proceed regardless of when vaccine was administered.

The American Cancer Society recommends women in their 40s get a screening mammogram every year. We have seven locations and three easy ways to schedule:
