First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study is looking at genetic material from tumors (circulating tumor DNA) found in the blood of 30 people with advanced or metastatic HER2-low breast cancer. The goal is to identify specific mutations in these cancers. This is an observational study, meaning no new treatment is being tested, but the findings could help guide future research and treatment choices.
