Hormone replacement therapy is taking another hit. Over the last several years, HRT has been linked to an increased risk of heart attacks, strokes and breast cancer. A new study involving more than 900,000 Danish women suggests that HRT use also increases the chance of being diagnosed with ovarian cancer. Although the increase is significant at almost 40 percent, the overall risk remained low. In every 8,300 women taking postmenopausal hormones there would be one additional case of ovarian cancer. The increased likelihood of developing ovarian cancer dropped within a year of stopping the hormones. Within two years, the risk of ovarian cancer was no higher than that of women who had never taking HRT.
