I start Tamoxifen tomorrow. Am hesitant about this drug but must do it. Just like chemo, surgery and radiation. "Buck up and deal with it Chickie!"
Tamoxifen (Nolvadex®) is a drug, takenorallyas a tablet, which interferes with the activity of estrogen, a female hormone. Estrogen can promote the development ofcancerin the breast. Tamoxifen is approved by the U.S. Food and Drug Administration (FDA) for the prevention of breast cancer and for the treatment of breast cancer, as well as other types of cancer.
Tamoxifen has been used for more than 30 years to treat breast cancer in women and men. Tamoxifen is used to treat patients with early-stagebreast cancer, as well as those withmetastaticbreast cancer (cancer that has spread to other parts of the body). Asadjuvant therapy(treatment given after the primary treatment to increase the chances of acure), tamoxifen helps prevent the original breast cancer from returning and also helps prevent the development of new cancers in the other breast. As treatment for metastatic breast cancer, the drug slows or stops the growth of cancercellsthat are present in the body.
Tamoxifen has been used for almost 10 years to reduce the risk of breast cancer in women who are at increased risk of developing breast cancer. Tamoxifen is also used to treat women withductal carcinoma in situ(DCIS), a noninvasive condition that sometimes leads to invasive breast cancer.
How does Tamoxifen work?
Estrogen can promote the growth of breast cancer cells. Some breast cancers are classified as estrogen receptor-positive (also known as hormone sensitive), which means that they have aproteinto which estrogen will bind. These breast cancer cells need estrogen to grow. Tamoxifen works against the effects of estrogen on these cells. It is often called anantiestrogenor a SERM (Selective Estrogen Receptor Modulator).
Studies have shown that tamoxifen is only effective in treating estrogen receptor-positive breast cancers. Therefore, thetumor’shormone receptorstatus should be determined before deciding on treatment options for breast cancer.
Although tamoxifen acts against the effects of estrogen in breasttissue, it acts like estrogen in other tissue. This means that women who take tamoxifen may derive many of the beneficial effects of menopausal estrogen replacement therapy, such as a decreased risk ofosteoporosis.

Makes one want to run right out and get some right?!
Tomorrow morning - day 1 of 5 years or 1,825 doses/days. Huge hoping here that I experience zero side effects.
