Breast Screening (Mammogram Programme)

The NHS Breast Screening Programme uses mammograms (breast X-rays) to detect breast cancer at an early stage, often before any symptoms can be seen or felt. Early detection can improve treatment outcomes and survival rates. 

  • Women registered with a GP are routinely invited for breast screening from age 50 up to their 71st birthday
  • The first invitation is usually received between ages 50 and 53.
  • Screening is offered every 3 years until age 71. 
  • Women aged 71 and over are not automatically invited but can self-refer every 3 years by contacting their local breast screening service. 
  • Screening takes place at a hospital or mobile screening unit.
  • Each breast is positioned on the mammography machine and gently compressed to obtain clear X-ray images. 
  • The appointment usually takes around 30 minutes, with the mammogram itself taking only a few minutes
  • No signs of breast cancer are found.
  • The patient will be invited again in 3 years if still within the screening age range. 
  • Some women are asked to attend for additional tests.
  • Being recalled does not mean cancer has been diagnosed.
  • Further tests may include additional mammograms, ultrasound scans, or biopsies. 
  • Breast cancer is the most common cancer in women in the UK. 
  • Screening can identify cancers when they are too small to see or feel. 
  • Earlier diagnosis often means treatment is simpler and more effective.
