Long-term, estrogen-only hormone therapy MAY increase breast cancer risk

On NBC Nightly News, NBC’s Chief Science Correspondent Robert Bazell said that a new study “shows that all long-term hormone use after ten years or more increases the risk” of breast cancer.

The AP reports that investigators “tracked the health of about 60,000 nurses and found that use of any kind of hormones for 10 years or more slightly raised the chances of developing breast cancer.”

HealthDay reports that the researchers found that “women who used estrogen-only therapy after menopause had 22 percent increased risk for breast cancer if they used it for 10 to 14.9 years, and 43 percent greater risk if they used it longer than 15 years.”

The research, scheduled to be presented at the American Association for Cancer Research meeting, “was funded by the National Cancer Institute, part of the U.S. National Institutes of Health.”
