Effectively communicating the risks and benefits of breast cancer screening to patients involves providing comprehensive, tailored information to enable informed decision-making , ().

  • Tailor Information and Explore Beliefs: It is crucial to tailor the information provided, considering its format, content, and the patient's individual needs and beliefs , (). Explore the woman's expectations about breast screening .
  • Explain the Screening Process: Clearly explain what to expect, including that an invitation will arrive by post and can be rearranged if inconvenient . Describe that the appointment typically lasts about 30 minutes and may be at a mobile, hospital-based, or permanent unit . Inform patients that they will need to remove clothes from the top part of their body, including their bra, and should avoid talcum powder or spray-on deodorant on the day of screening as it may affect the mammogram . Explain that each breast is compressed, which some women find uncomfortable or painful, but is necessary for a good-quality image . Patients should be advised to await contact from the breast screening service regarding results and any follow-up .
  • Discuss Benefits: Emphasise that mammography is the most accurate method for the early detection of breast cancer . Early detection can lead to improved outcomes .
  • Discuss Harms and Risks: Inform patients about potential discomfort or pain during the mammogram due to breast compression . Explain that approximately 1 in 23 women are recalled for further tests because their mammogram shows that more tests are needed, but most of these women will not have breast cancer . Other risks include the possibility that mammography might miss a cancer, especially in women with dense breasts, the increased likelihood of further investigations, possible overdiagnosis, the risk associated with exposure to radiation, and the potential psychological impact of a recall visit .
  • Provide Written Information and Resources: Always provide written information, such as the Public Health England (PHE) Breast screening information leaflets, the NHS leaflet on Breast cancer screening, and the NHS England leaflet "Breast screening: helping women decide" ,. Signpost to further information from organisations like Cancer Research UK and provide details for local and national support groups ,.
  • Address Lifestyle and Risk Factors: Discuss modifiable risk factors for breast cancer, including advising on reduction of alcohol intake, maintenance of a healthy weight, increasing physical exercise, and smoking cessation ,. Inform women that having a first child at a younger age, having a large family, and breastfeeding may reduce the risk of breast cancer ,. Provide appropriate information on oral contraceptives and hormone replacement therapy (HRT), noting that for women over 35 with a family history, there is an increased risk of breast cancer associated with combined hormonal contraception ,.
  • Consider Specific Patient Needs:
    • For women with breast implants, explain that some breast tissue may be obscured by the implant during routine mammography, making early detection more difficult, and additional images may be taken . The NHS leaflet on Breast implants and breast screening can be helpful .
    • For women with a physical disability that may make screening difficult, advise them to contact the local breast screening service for advice on technical feasibility and the best place to attend .
    • For women with a learning disability or lacking mental capacity, assess for fluctuating capacity and, if ongoing, make a 'best interests' decision in consultation with family, friends, or carers, considering the woman's past views and risk factors . The NHS leaflet "An Easy Guide to Breast Screening" may be useful .
  • Offer Support and Review: Offer support, such as risk counselling, psychological counselling, and risk management advice, to women with ongoing concerns . Advise patients that they can bring a family member or friend to appointments ,. Emphasise that eligibility for surveillance should be reviewed if family history changes .
