Or maybe you have a high risk of getting breast cancer. Perhaps you have a strong family history, genetic predisposition and/or have had some concerning biopsies. You don’t want to have to face cancer; you’d rather try to prevent it in the first place. Either way, you’re a good candidate — if you’re premenopausal — for tamoxifen. A powerful chemotherapy treatment that’s been used for more than 30 years, tamoxifen decreases the chances of breast cancer occurrence or recurrence by about 50%, according to Worta Mc Caskill-Stevens, MD, MS, medical oncologist and Chief of the Community Oncology and Prevention Trials Research Group at the National Cancer Institute. That benefit doesn’t disappear the minute you pop your last pill, either.

To compare between-group post-therapy changes in immunohistochemistry (IHC) markers: CD-68 macrophage marker as a surrogate for response to therapy, p16 and COX-2. To compare post-therapy changes in breast density, quantitative estimate, between arms. To compare post-therapy breast tissue and plasma levels of TAM and its metabolites (N-desmethyl tamoxifen [NDT], [E] and [Z] isomers of 4-hydroxytamoxifen [4-OHT], N-desmethyl-4-hydroxytamoxifen [endoxifen]). To compare post-therapy breast tissue and plasma levels of estradiol and progesterone between arms (optional). To compare the post-therapy fraction of participants demonstrating "no residual DCIS". To compare post-therapy changes in plasma proteins involved in coagulation: factors VIII and IX, von Willebrand factor, total protein S between arms.
