New York: Taking tamoxifen is tied to a sharply reduced risk of a second breast cancer among women who carry the BRCA1 or BRCA2 "breast cancer genes," new research shows.Women with mutations of those genes are much more likely to develop breast and ovarian cancer than other women. Some - like Angelina Jolie - will opt to have their breasts removed preemptively, which reduces breast cancer risk by more than 95 percent.Other women may choose to have their ovaries removed, which cuts breast cancer risk in half. The new findings suggest taking tamoxifen may be another breast-cancer-preventing option for those women, whether or not they have already had cancer once, researchers said."In light of our finding, women with a BRCA1 or BRCA2 mutation should review their cancer risk management options with their specialist clinician," Dr. Kelly-Anne Phillips of the Peter MacCallum Cancer Centre in Victoria, Australia, the study`s lead author, told Reuters Health.
