New study aims to ease Post-Mastectomy pain with targeted nerve blocks
NCT ID NCT07510269
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of nerve blocks to see which one works better for pain after mastectomy surgery. About 66 women having a mastectomy will receive one of the two blocks before surgery. The goal is to find a method that reduces pain, lowers the need for painkillers, and helps patients recover faster.
