MIT Develops Wearable Ultrasound for Early Breast Cancer Detection

Engineers and scientists from MIT's Research Laboratory of Electronics (RLE) and Koch Institute for Integrative Cancer Research have developed a wearable ultrasound device designed to enable earlier and more frequent at-home breast cancer screening. Published in *Science Advances* on February 2, 2026, this technology aims to address limitations of traditional mammography, particularly for women with dense breast tissue, and to overcome barriers to regular clinical visits. The device consists of a flexible, 3D-printed patch containing a honeycomb array of piezoelectric transducers that can be affixed to a bra and rotated to image the entire breast area. This patch connects to a small, motorized tracker, about the size of a postage stamp, which scans the transducers and transmits data to a smartphone or tablet for artificial intelligence-powered analysis. In initial tests with volunteers at MIT's Koch Institute, the system successfully imaged cysts as small as 0.3 centimeters, which is the smallest size generally detectable by hand. The entire system is about the size of a smartphone. Lead author Canan Dagdeviren, an associate professor at MIT, stated the goal is to create a 'new paradigm in cancer detection' by making early diagnosis more accessible. The researchers plan to commercialize the technology, further miniaturize the system, and develop the AI interpretation for potential home use, potentially incorporating a 'traffic light' system for results. Clinical trials are anticipated to begin in 2026 to further validate its efficacy.
