What is Tamoxifen?

Tamoxifen is a hormone therapy for breast cancer in both women and men. It lowers the risk of early breast cancer coming back (recurring) after surgery or developing in the other breast. It can also control advanced breast cancer for some time.

Tamoxifen is sometimes used in women who have a high risk of breast cancer, to prevent breast cancer from developing.

How Tamoxifen works?

Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive. Tamoxifen is usually prescribed for people who have oestrogen receptors in the breast cancer cells. These cells are called oestrogen receptor positive or ER positive.

Tamoxifen works by locking on to the oestrogen receptors to block oestrogen from attaching to them. The oestrogen cannot then stimulate the cells to divide and grow.
