COVID-19 Vaccine Impact on Mammogram Results

There is no link between the COVID-19 vaccine and breast cancer. The COVID-19 vaccine can cause a temporary enlargement of lymph nodes, like other vaccines, that may have mammograms appear abnormal when there is no indication of cancer. The lymph nodes can become swollen as a normal immune response to the vaccine. Lymph node enlargement will return to normal a few weeks after the vaccine regimen is finished. The Society of Breast Imaging recommends that yearly screening mammograms should be scheduled before the first dose of the COVID-19 vaccine or 4 to 6 weeks following a second dose.
