Study Shows Tamoxifen a Blessing for Many -- a Curse for a Few
Although tamoxifen can be prescribed in the U.S. for any healthy, high-risk women who are worried about developing breast cancer, Pearson urges such women not to just take it by prescription but to enroll in a study where they will be closely watched.
Van Leeuwen says that all women taking tamoxifen should know the warning signs of uterine cancer. "Any woman who has taken tamoxifen for two or more years should be very watchful for any symptoms of [uterine] cancer, particularly postmenopausal vaginal bleeding. This is true even if tamoxifen has been discontinued for quite some time, since we still do not know when or whether the [uterine] cancer risk disappears," she says.
