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 asks your patient questions about whether they have had the Covid-19 vaccination in last 6 weeks before their screening mammogram, so the consultant radiologist has this information when they interpret your patient’s mammogram images.
