BreastScreen Norway

BreastScreen Norway 

Breast cancer is the most common cancer among women in Norway. 4215 women were diagnosed with breast cancer in 2024.

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 early 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 at the Norwegian Institute of Public Health. 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.
