Breast Screening

Breast screening takes place every 3 years for women aged 50 -70. To ensure everyone eligible receives an invitation at the correct screening interval each time, GP practices are always screened in the same order.

Appointments are made and women will receive notification 3 weeks in advance by post. The appointments are allocated but you can contact us (028 71611363) to change your appointment if it is unsuitable. Requests to change an appointment can also be emailed ( and a response will be provided within 24 hours.

All breast screening has now been phased out onto mobile screening units. Anyone who was normally screened in Altnagelvin Static Unit will now be called to a Mobile Breast Screening Unit. However if an appointment does not suit it may be possible to rearrange the appointment if they wish. The locations the mobile unit is used at are:

  • Altnagelvin (adjacent to Breast Screening Unit)
  • Shantallow Health Centre
  • Strabane (Greenfield nursing home)
  • Omagh (Omagh Library)
  • Enniskillen (Lakeland Forum Car Park)
  • Limavady (Roe Valley Hospital Car Park)
  • Coleraine (Dunnes Store car park)

Before the mammogram the radiographer will explain the procedure to you. You will be told to expect the results by post within 3 weeks.

Most women will receive a normal result however about 4 in every 100 women screened will need to return for further tests. This does not necessarily mean that anything is wrong, as 3 out of 4 women who are recalled will receive a normal result when the further tests have been completed.

Please see below the locations for the mobile and the screening orders up until July 2017:

A member of the Breast Screening Team may be available to attend community groups to talk about breast screening, give information and answer queries. To enquire about this service contact the breast screening unit on 028 71611443 and ask to speak to a member of the mammography team.

The Western Trust recently have taken delivery of two new mobile breast screening units, each of which have the latest digital mammographic x-ray equipment installed on board. The two new mobile screening units offer an enhanced patient experience in a more comfortable environment. The x-ray units in the mobiles produce clearer digital images of the breasts for Radiographers to check immediately after screening, to help reduce the number of women who need to be recalled. A major design feature included in the new units are improvements in access particularly for less able patients, including more space within the unit, a disabled access lift, illuminated step treads to reduce the trip hazard for visually impaired clients and a staff call feature for patients who cannot manage the steps.
