Blood markers may reveal hormone therapy success in breast cancer

This study looked at whether tiny molecules called microRNAs in the blood can help predict if hormone therapy will work for women with advanced breast cancer. Researchers tested blood samples from 39 women before and after one month of treatment with tamoxifen or an aromatase inhibitor. The goal was to see if these microRNAs could serve as early indicators of treatment response, potentially guiding more personalized care in the future.
