Why was I told to wait a month after getting the vaccine before getting a mammogram?

Some people experience temporary swelling of lymph nodes under their arm after getting the Pfizer or Moderna vaccines. This is part of the immune system’s expected response to receiving the vaccine. Sometimes this has been mistaken for a sign of possible spread of breast cancer to the lymph nodes; therefore, delaying the mammogram can reduce the chance of being confused by this finding. If you are concerned about delaying one, contact your healthcare provider.
