Tamoxifen: What Is It?
Tamoxifen is a medication primarily used in the treatment of breast cancer. It belongs to a class of drugs known as selective estrogen receptor modulators (SERMs). This article explores what tamoxifen is, how it works, its uses, side tamoxifen-for-sale effects, and frequently asked questions.
What Is Tamoxifen?
Tamoxifen is an oral medication that is commonly prescribed for women diagnosed with certain types of breast cancer. It is particularly effective in treating hormone receptor-positive breast cancers, where the growth of cancer cells is fueled by estrogen.
How Does Tamoxifen Work?
The mechanism of action of tamoxifen involves binding to estrogen receptors on breast cells. This action blocks estrogen from attaching to these receptors, thereby preventing the growth and proliferation of cancerous cells. Additionally, tamoxifen can have an agonistic effect on other tissues, such as bone and the uterus.
