Breast screening

Published on 13 April 2022

Breast screening is a way of finding a breast cancer when it's too small to see or feel. It involves having an x-ray of the breast, called a mammogram. Screening is the best way to detect breast cancer early. Breast screening does not prevent breast cancer, but it can increase survival rates.

Where does the Breast Screening Service take place?

We commission the breast screening service. It operates out of six screening centres. Details of the centres and the areas they screen in Scotland are available on NHS Inform.

You can also find contact information there. Each centre has a Clinical Director who's responsible for the service.

Women receive invites to attend for their breast mammography appointment at either a mobile unit or a screening centre.

Who gets the breast screening test and how does it work?

Women between the ages of 50 and 70 (up to their 71st birthday) get invites for breast screening once every three years. The timing of an appointment depends on the GP practice a woman is registered at.

Each GP practice takes part in the breast screening programme once every three years. This means that women may not receive their first invitation until they are nearly 53. Women who are 71 and over can self refer for breast screening by contacting their local screening centre.

The most effective way of finding breast cancer early is by mammography. At an appointment, two mammograms of each breast are taken. The results from screening are then sent to the women and their GP surgery. Around 5 out of 100 women who have the screening will need further tests.
