What is Tamoxifen?

Tamoxifen (brand names: Nolvadex, Soltamox) is a selective estrogen receptor modulator (SERM) used:

1. After surgery to reduce the risk of hormone receptor-positive, early-stage breast cancer coming back (recurring) in women or men

2. To treat advanced-stage, hormone receptor-positive breast cancer in women or men

3. After surgery to reduce the risk of invasive breast cancer in women diagnosed with hormone receptor-positive DCIS (ductal carcinoma in situ)

4. To reduce the risk of breast cancer in women with a higher-than-average risk of the disease who haven’t been diagnosed
 

How Tamoxifen works?

Tamoxifen blocks the effects of estrogen on hormone receptor-positive breast cancer cells by sitting in the estrogen receptors on the cells. If tamoxifen is in the receptor, estrogen can’t attach to the cancer cell and the cell doesn’t receive estrogen’s signals to grow and multiply. Tamoxifen won’t work on hormone receptor-negative breast cancer.

Benefits of tamoxifen

Tamoxifen has been used to treat hormone receptor-positive breast cancer in millions of women and men. Although an aromatase inhibitor usually is the first hormonal therapy medicine choice for post-menopausal women, tamoxifen is the first choice for pre-menopausal women and is still a good choice for post-menopausal women who can't take an aromatase inhibitor.

Tamoxifen can:

1. Reduce the risk of breast cancer coming back by 40% to 50% in post-menopausal women and by 30% to 50% in pre-menopausal women.

2. Reduce the risk of a new cancer developing in the other breast by about 50%.

Tamoxifen offers other health benefits that aren't related to treating cancer. Because it’s a SERM, it selectively either blocks or activates estrogen's action on specific cells. While tamoxifen blocks estrogen's action on breast cells, it also activates estrogen's action in bone and liver cells. So tamoxifen can:

1. Help stop bone loss after menopause.

2. Lower cholesterol levels.
