Coronavirus pandemic information

Updated April 14, 2021

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).

BreastScreen Norway 

Breast cancer is the most common cancer among women in Norway. 3627 women were diagnosed with breast cancer in 2019.

BreastScreen Norway invites all women aged 50-69 to have a breast cancer check in the form of a screening mammogram (X-ray imaging of the breast) every other year.

The goal of the program is to find eraly stage breast cancer so that fewer women die from the disease.

BreastScreen Norway is a public health service administered by the Cancer Registry of Norway. Participation is voluntary.

For women who are invited

All women aged 50-69 receive a personal invitation letter with a suggested appointment for a screening mammogram. This invitation comes with approximately a two year interval.

Mammography does not detect all breast cancers. Breast cancer can also be found between two mammograms. Always check with your doctor if you notice a new lump or changes in your breast, even if you just had a mammogram.
