However, Evista was not as effective in preventing non-invasive breast cancers as tamoxifen, according to a report, which appeared in the Journal of the American Medical Association.
But the debate over Evista's fate goes on.

"We feel that the drug should not be approved, because it's an approach that's going expose healthy women to increased risks for one disease [heart trouble] to protect them from another," said Amy Allina, a program director at the National Women's Health Network.
"Even women at very high risk for breast cancer are taking on other risks with this drug," Allina said. "If they are not at very high risk of breast cancer, they are probably getting more harm than help," she said.
But Lichtenfeld contends that Evista has been long used by doctors in the treatment of osteoporosis, so physicians will be more comfortable in prescribing it to women to help prevent breast cancer. "Doctors are not talking to women about breast cancer prevention, and it's an area where more attention needs to be paid," the cancer society expert said.
"Both Evista and tamoxifen have risks," Lichtenfeld acknowledged. "But Evista has been used widely for the treatment of osteoporosis, so physicians are comfortable with that. While this is not a perfect answer to the increased risk of breast cancer, it is the best answer we have right now," he said.
The drug's maker was optimistic about the panel's decision. "Today is an especially good day for postmenopausal women," Gwen Krivi, vice president of Lilly Research Laboratories, said in a prepared statement. "If approved, Evista would be the first and only therapy available to address two leading health issues for postmenopausal women --osteoporosis and breast cancer. Following today's vote, our intention is to continue working with the FDA to make this important option a reality for patients."
Eli Lilly and Evista have a somewhat checkered past, however. In 2005, the company plead guilty and paid a $36 million fine for illegally promoting Evista to reduce the risk of breast cancer, a violation of the Food, Drug, and Cosmetic Act.
