Radiologists Report Swelling From Vaccines Seen on Mammograms

COVID-19 vaccine related swelling caused anxiety in some patients

Some patients were reporting swollen lymph nodes after getting one of the approved COVID-19 vaccines. This side effect was expected, as lymph nodes often become swollen when the body is fighting off an invader. More worrisome for some was when the swollen nodes appeared as white blobs on mammograms, causing some patients and their doctors to fear that they were an indication of breast cancer and call for biopsies.

The patient care committee of the Society of Breast Imaging (SBI) has since recommended that people schedule their routine breast cancer screenings for before or for weeks after they get their COVID-19 vaccines to avoid unnecessary anxiety. For more on this story, head over to CNN.
