Breast cancer prevention study halted: tamoxifen pill vs. gel tested
NCT ID NCT04570956
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if a tamoxifen skin gel could work as well as the pill to lower breast cancer risk in women with certain high-risk breast conditions. The trial enrolled 65 women and compared short-term changes in breast tissue. However, the study was terminated early, so results are limited.
