Covid vaccines

The Covid 19 vaccines may, in 10-20% of women, cause swollen lymph nodes in the armpit and breast on the same side as the vaccine was given.

When attending screening, you will therefore be asked if you have taken a covid vaccine. You will be asked about the date of the vaccine, and in which arm the vaccine was placed.

This information is helpful when doctors evaluate your mammograms, as swollen lymph nodes can also be a sign of breast cancer (Norwegian).

Delayed invitations

Inviations in BreastScreen Norway are delayed, and your invitation to screening is likely to come later than normal (the ordinary sceening routine is every 24 month).
