First seen Feb 26, 2026 · Last updated May 29, 2026 · Updated 8 times

Summary

This study tests whether a special type of ultrasound, using a contrast dye called Definity, can measure pressure inside breast tumors to predict how well chemotherapy is working. About 200 women with locally advanced breast cancer will get three of these ultrasounds before and during their treatment. The goal is to see if this imaging method can tell early on whether the cancer is responding, which could help doctors adjust treatment sooner.
