G Tamoxifen is also used to treat advanced breast cancer in premenopausal women whose cancer is have spread. It has also been prescribed off-label to prevent recurrence of some types of breast cancer after mastectomy.

Uses for G Tamoxifen

G Tamoxifen is used to treat and prevent the spread of hormone-receptor positive breast cancer in women and men. In women, it is most commonly used to help reduce the risk of breast cancer recurrence; however, it can be used to help slow or stop the growth of breast cancer, particularly in combination with chemotherapy or other medications. In men, tamoxifen may be used to help prevent or slow down the growth of advanced prostate cancer.

Mechanism of Action

G Tamoxifen works by blocking the action of the hormone estrogen. Estrogen can promote the growth and spread of certain types of breast cancer. By blocking estrogen’s action, tamoxifen can help slow or stop the growth of these breast cancer cells. G Tamoxifen works by competing with estrogen for binding sites on the receptor cells. When estrogen binds to a receptor cell, a chemical message is sent to the cell nucleus telling it to produce proteins that promote cell growth. G Tamoxifen limits the number of times estrogen can bind to the cell and send the message to grow.

The effects of tamoxifen can vary from person to person. In most cases, it will start to show effects within 2-4 weeks.
