Tamoxifen: What Is It?

Tamoxifen is a medication primarily used to treat breast cancer. It falls under the category of selective estrogen receptor modulators (SERMs), which means it interacts with estrogen receptors in particular tissues, providing both estrogen-like and anti-estrogen effects depending on the target tissue.

How Does Tamoxifen Work?

The main action of tamoxifen involves blocking estrogen’s ability to bind to its receptor in breast tissue. Since many types of breast cancer are fueled by estrogen, inhibiting this hormone can help slow or stop the growth of the cancer cells. Additionally, tamoxifen can have an estrogen-like effect on bone and uterine tissues, which may lead to positive effects such as increased bone density.

Indications for Use

Tamoxifen is commonly prescribed for:

• Early-stage breast cancer to reduce the risk of recurrence
