When scheduling your mammogram, it’s important to understand how the COVID-19 vaccine may play a part.
The COVID-19 vaccine, as well as many other vaccines, can cause swollen lymph nodes in some people, which may be identified on breast imaging. This is a normal reaction to the vaccine, and they should resolve on their own.
According to Dr. Jessica Kaniowski, Diagnostic Radiologist at Beaumont Hospital, Dearborn, “The likelihood of the vaccine affecting your mammogram results is low. If you have a concern, consider scheduling your mammogram before you receive the vaccine or 4 weeks after you receive your second dose. However, patients should not delay any recommended follow up breast imaging."
How do the COVID-19 vaccines effect my mammogram results?
The COVID-19 vaccines can cause swollen lymph nodes in the axilla/armpit area in some people, which may be identified on breast imaging. Swollen lymph nodes are a normal reaction to a vaccine and should resolve on their own.
I am scheduled to get the COVID-19 vaccine. Should I wait to schedule my screening mammogram?

Should I tell the technologist I had the vaccine?
Yes, please let the technologist know when, and in what arm, you received the vaccine.
What happens if swollen lymph nodes are identified on my screening mammogram?
A short-term follow-up exam will be considered 4-12 weeks following your second vaccine dose.
I was called back for additional imaging and I just got vaccinated, should I still come for my appointment?
Patients should not delay any recommended follow up breast imaging.
