- Question from AnnG: Is there any evidence to show that tamoxifen prevents the development of hormone-positive tumors at a later date in ER/PR-negative patients?
- Answers - Kathy D. Miller, M.D. The short answer is no. In most women who have two separate primary breast cancers, those two breast cancers have the same ER status. So in most women whose initial breast cancer was ER-negative and who do develop a second breast cancer, that second breast cancer is also ER-negative. In women with ER-negative tumors, tamoxifen doesn't seem to decrease the risk of developing a second primary cancer.
