MIT Develops Ultrasound Bra for At-Home Breast Cancer Detection

• MIT researchers have developed a novel ultrasound bra that allows women to monitor their breast health at home, potentially improving early detection of breast cancer.
• The wearable technology utilizes a 3D-printed patch with a tiny tracker that captures real-time ultrasound images from multiple angles, suitable for all breast types.
• Clinical trials are underway, with hopes for FDA approval within five years, aiming to provide a more accessible and frequent screening method, especially for high-risk individuals and those in lower-income countries.
• The device could significantly improve survival rates by detecting cancer earlier, addressing the concerning statistic that half of high-risk women develop breast cancer between annual mammograms.

A team at MIT has developed a groundbreaking ultrasound bra designed to detect breast cancer at home, potentially revolutionizing early detection and improving survival rates. Inspired by the late-stage diagnosis of a loved one, Professor Canan Dagdeviren and her team spent seven years creating a wearable patch that allows women to monitor changes in their breast health over time.

The device, made using a 3D printer, features a plastic patch that fits into a bra. A tiny tracker moves around the patch, rotating 360 degrees to capture real-time ultrasound images from multiple angles. This technology is effective on all breast types, including dense breasts, and can be worn for just a few minutes each day.

Potential Impact on Early Detection

Early detection is critical in breast cancer, with survival rates as high as 98% when detected early, but dropping to just 22% in late stages. Currently, annual mammogram screenings are recommended for women over 40, but half of high-risk women develop breast cancer between these screenings. The ultrasound patch offers a potential solution for more frequent monitoring.

"The wearable technology that we provide [is] based on ultrasound technology," explained Prof. Dagdeviren, highlighting its ability to provide accessible screening.

Accessibility and Cost

Beyond improving early detection, the ultrasound patch aims to provide access to screening for women in lower-income countries where regular mammograms may not be readily available. While the current cost to produce the patch is $1,500, researchers believe mass production could significantly lower the price.

Clinical Trials and Future Availability

The ultrasound patch is currently undergoing larger-scale clinical trials, with hopes of FDA approval within the next five years. If approved, this technology could save millions of lives each year by enabling earlier and more frequent breast cancer detection.

"Back then it was just a dream on a piece of paper. Now it’s real. And we touch many people’s lives and bodies," Prof. Dagdeviren stated, reflecting on the journey from concept to reality.
