A system that uses harmless microwaves combined with artificial intelligence (AI) was able to detect even small, early-stage breast tumors without exposing women to radiation.

“A prototype device — the culmination of 15 years of work on the use of microwaves for tumor detection, not imaging — cost less than $5,000 to build.

By comparing the tissue composition of one breast with the other, the system is sensitive enough to detect anomalies less than one centimeter in diameter.

A negative result could quickly rule out cancer, while a positive result would trigger referral for more expensive tests using mammography or magnetic resonance imaging (MRI).
