Summary

This study looked back at medical records of over 1,600 adults in Russia with HER2-low breast cancer that had spread or could not be removed by surgery. Researchers wanted to understand how common this type is, what patient characteristics are, and how doctors actually diagnose and treat it in everyday practice. The goal was to gather information, not to test a new treatment.
