Tamoxifen: What Is It?
Tamoxifen is a medication primarily used in the treatment of breast cancer. It plays a crucial role in managing hormone receptor-positive breast tumors by blocking estrogen’s effects https://tamoxifencycle.com/prod/nolvo/ on the breast tissue.
How Does Tamoxifen Work?
Tamoxifen functions as a selective estrogen receptor modulator (SERM). This means it can block or activate estrogen receptors in different tissues, depending on the context. In breast tissue, it acts as an estrogen antagonist, which helps to inhibit tumor growth that depends on estrogen.

- Blocks estrogen from binding to its receptors in breast cells.
- Reduces the risk of recurrence in women who have undergone surgery for breast cancer.
- Can prevent the development of breast cancer in high-risk women.
