Breast screening reduces the number of deaths from breast cancer by finding signs of disease at an early stage.We aim to detect breast cancer before it can be felt by hand or seen, in order to give women the best chance ofsuccessful treatment.
NHS Digital publishes annual reports of breast cancer screening performance in England. Its latestreport, published on 31 January, covers the year 1 April 2016 to 31 March 2017.

During those 12 months, the NHS Breast Screening Programme invited just under 3 million women for screening and we screened 2.2 million, an increase of 1.3% on the previous year.Of those screened, just over 18,402 women were diagnosed with breast cancer, which equatesto 8.4 cancers for every 1,000 women screened.
Recent media coverage has focused on the fact that breast screening uptake has fallen. Uptake measures the proportion of women invited who actually attend and are screened within 6 months of their invitation.
The programme’s acceptable standard for uptake is 70%. This continues to be achieved but there has been a disappointing decline over recent years. Uptake in 2016 to 2017was 71.1%, which was a reduction of 1% on the previous year. In women invited for the first time, uptake fell by around 2% to 60.3%.
The good news is that most women (around 88%) who have previously attended screening in the past 5 years continue to take up the offer. We believe this reflects satisfaction with the service from our regular attenders.
National and local initiatives
We are continually investing in initiatives to address declining uptake and help ensure equality of access to screening. Itis important that the information we givewomen before we offer screeninghelps them make an informed decision bydiscussing the known benefits as well asthe possible risks. Our new breast screening: easy guide, along with local initiatives such as text and GP reminders, are among the ways we are getting the information through to women so they can decide whether screening is right for them.
We also offer second timed appointments to women who have previously not attended. These are second appointments, with a date and time, for women who do not attend their initial appointment.
Breast screening is a 2-stage process. Women attending have mammography (breast x-rays) and for the majority (96 out of every 100 screened), no abnormalities are found by the professionals who interpret the images.
The other 4 out of every 100 women screened are invited for further tests at an assessment clinic. Of women attending assessment, just under half will have needle biopsies to confirm whether or not they have cancer. We now detect virtually all cancers (97.8%) at this stage without women having to undergo a surgical biopsy under general anaesthetic. This:
- minimises the number of surgical procedures women need
- reduces anxiety
- allows earlier treatment planning
Benefits of early diagnosis
During 2016 to 2017, of all cancers detected thatwere invasive – and thereforehad the potential to spread to other parts of the body – just over half (52.4%) were detected when they were small (<15mm in diameter).
Itis good newsthat disease is beingdetected at this early pre-clinical phase. This finding is supported by an audit which looked at the stage of presentation of breast cancer from stage 1 (being early in the disease progression) to stage 4 (most advanced stage of disease progression at diagnosis).
Of all women presenting with early stage disease (stage 1), 51% presented through the breast screening programme, where the stage was known. In comparison, 37% of women with stage 1 disease were diagnosed following a 2-week wait referral appointment from their GP.
Most women attending breast screening have been screened in the previous 5 years, so this makes the diagnosis of later stage disease less likely within the programme. Of all women presenting with later stage disease (stage 4), 7% of women were diagnosed through screening comparedto 45% diagnosed following a 2-week wait appointment organised through their GP. For more information see the National Cancer Intelligence Network (NCIN) website.
As the national programme manager, I strongly urge women aged between 50 and 70 to read our Helping you decide information leaflet so they canmake an informed choice as to whether to attend.
