New ultrasound trick spots cancerous breast lumps without a needle

This study tested whether a special ultrasound technique called strain elastography can help tell the difference between harmless and cancerous breast lumps. Researchers measured how stiff each lump was, since cancer tends to be stiffer. The goal was to improve diagnosis and reduce the number of unnecessary biopsies. The study included 30 women with solid breast lumps who were already scheduled for a biopsy.
