Breast Cancer BRAs Study (Breast Cancer Biomechanics of Radiotherapy And Surgery)

August 20, 2025 updated by: Portsmouth Hospitals NHS Trust

Breast Cancer BRAs Study (Breast Cancer Biomechanics of Radiotherapy And Surgery): The Effects of Breast Surgery and Radiotherapy on the Breast Biomechanics and Breast Support Requirements of Women Treated for Breast Cancer.

This study, delivered by Portsmouth Hospitals University NHS Trust in conjunction with the Research Group in Breast Health at the University of Portsmouth [1], aims to assess whether it is possible to test breast biomechanics in women who have had surgery with or without radiotherapy for the treatment of breast cancer.

Detailed Description

Breast cancer is an increasingly common condition, affecting >56,000 women a year in the UK. Surgery and radiotherapy are commonly used to treat breast cancer. Both these treatments can affect the structure and movement of the breast tissue, which is collectively called breast biomechanics. Breast biomechanics has been studied in healthy women and in female athletes, and across the menstrual cycle, menopause and pregnancy. Investigators know from this research that breast biomechanics can affect the type of bra support women need, which when optimised can improve comfort and quality of life as well as reduce the potential for tissue damage. However, breast biomechanics and associated breast garment support requirements (bra support) have not yet been significantly investigated in women undergoing breast cancer treatment.

Patients who would be eligible to participate in this study include women aged 18 or treated with surgery +/- radiotherapy for breast cancer that affects one of their breasts. Patients will be recruited from the Breast Unit at Queen Alexandra Hospital, Cosham. Participation in this study will involve attending the biomechanics testing laboratory at UoP after their surgery and/or after radiotherapy, and optionally before surgery too. 3D scans and sensors will be used to assess the structure and movement of the breast. Participants will be asked their views on the testing methods, as well as their bra requirements and exercise habits before and after breast cancer treatment. The information generated from this study could be used in the future to help design better bras for women treated for breast cancer. It could also help women make decisions about treatment based on evidence about how the breast is likely to move differently afterwards and improve satisfaction with treatment outcomes.
