Softer, harder, or just right? new ultrasound technique could spot breast cancer without a needle

This study tested a new ultrasound-based imaging method called Nonlinear Elasticity Mapping (NEM) to help tell apart benign and cancerous breast lumps. Researchers measured how breast tissue stretches and compresses, looking for patterns that match cancer. 172 women with breast findings on ultrasound took part. The goal was to see if NEM could reduce unnecessary biopsies by providing clearer information about a mass.
