Breast density is commonly referred to as the proportion of fibroglandular tissue (dense tissue) compared to adipose tissue (non-dense tissue) in the breast. High breast density is one of the strongest known risk factors for breast cancer and also makes cancers more difficult to detect on a mammogram. In Canada, over 40% of women have dense breasts, yet breast density is not consistently communicated or accessible to individuals. Improving breast density assessment could enhance early detection and empower women in making informed health decisions. This project will develop a small, wearable ultrasound device integrated into apparel that can safely and non-invasively estimate breast density. The technology is based on measuring how fast sound waves travel through breast tissue. This is a measurement that directly correlates with tissue density. Results will be reported as a continuous value or as one of four clinical density categories (A-D), based on national and international guidelines. By offering a user-friendly and accessible method for breast density assessment, this project supports personalized care for women across Canada, particularly in rural, remote, and underserved communities where access to mammography may be limited. The tool may complement existing breast cancer screening efforts, aid in risk stratification, and support health education initiatives. It also contributes to Canadian research into breast biomechanics and women's health, laying the groundwork for more equitable and individualized preventive care strategies. Ultimately, this work aligns with national efforts to reduce disparities in women's health outcomes and improve cancer prevention through innovation.
