A wearable ultrasound scanner could detect breast cancer earlier

 When breast cancer is diagnosed in the earliest stages, the survival rate is nearly 100 percent. However, for tumors detected in later stages, that rate drops to around 25 percent.

In hopes of improving the overall survival rate for breast cancer patients, MIT researchers have designed a wearable ultrasound device that could allow people to detect tumors when they are still in early stages. In particular, it could be valuable for patients at high risk of developing breast cancer in between routine mammograms.

The device is a flexible patch that can be attached to a bra, allowing the wearer to move an ultrasound tracker along the patch and image the breast tissue from different angles. In the new study, the researchers showed that they could obtain ultrasound images with resolution comparable to that of the ultrasound probes used in medical imaging centers.

"We changed the form factor of the ultrasound technology so that it can be used in your home. It's portable and easy to use, and provides real-time, user-friendly monitoring of breast tissue," says Canan Dagdeviren, an associate professor in MIT's Media Lab and the senior author of the study.

MIT graduate student Wenya Du, Research Scientist Lin Zhang, Emma Suh '23, and Dabin Lin, a professor at Xi'an Technological University, are the lead authors of the paper, which appears today in Science Advances.

A wearable diagnostic

For this project, Dagdeviren drew inspiration from her late aunt, Fatma Caliskanoglu, who was diagnosed with late-stage breast cancer at age 49, despite having regular cancer screens, and passed away six months later. At her aunt's bedside, Dagdeviren, then a postdoc at MIT, drew up a rough schematic of a diagnostic device that could be incorporated into a bra and would allow for more frequent screening of women at high risk for breast cancer
