A study published in the Journal of the American Medical Association is the first to report deaths from breast cancer among women who take hormone replacement therapy.

“In contrast to research two years ago, in this study we actually showed that hormone therapy is associated with an increased risk of death from breast cancer,” said Dr. Rowan Chlebowski of the Los Angeles Biomedical Research Institute, who led the study, according to Reuters.

Dr. Chlebowski explained these findings is also a follow-up of 11 years of study from the Women’s Health Initiative in 2002 which found that female users of estrogen plus progesterone for five years had higher rates of ovarian cancer, breast cancer, stroke and other health problems.

Dr Chlebowski’s team analyzed data from more than 12,000 women in this study. The team found that hormone therapy increases the risk of women dying from breast cancer is doubled, which is to 2.6 per 10,000 per year compared to the previous 1.3 per 10,000 women per year.

Nearly 24 percent of patients undergoing hormone therapy experienced breast cancer with tumor that has spread to lymph nodes.

“All cancer is frightening with unfavorable prognosis increases. And then for the first time we show breast cancer mortality also increased significantly,” said Dr. Chlebowski.

But Dr. Chlebowski said that the average age of women according to the Women’s Health Initiative study was 63 years, namely the last few years of menopause.
