First seen Apr 18, 2026 · Last updated Jun 13, 2026 · Updated 11 times

Summary

This study looked at whether it's possible to measure certain substances called oxysterols in the blood of breast cancer patients. 29 women taking hormonal therapy (tamoxifen or anti-aromatase drugs) had their blood tested before and 28 days after starting treatment. The goal was to see if these measurements are feasible, not to change treatment.
