COVID-19 vaccination and breast screening

There is no evidence that the COVID-19 disease or COVID-19 vaccination has any adverse effect on the breast tissue. Some recently published medical studies have reported a small incidence of mild lymph gland swelling in the axilla on the side of the inoculation for up to 6 weeks after the vaccination.

BreastScreen WA is not recommending that women delay or reschedule their screening appointments.

BreastScreen WA is asking your patient questions about the date, arm and brand of COVID-19 inoculation, so the consultant radiologist has this information when they interpret your patient’s mammogram images.

If you have any queries about this matter, please contact BreastScreen WA’s Liaison GP at
