It's interesting when a drug is re-purposed into something aimed at fighting cancer, but that is what has happened to Evista, a prescription drug made by Eli Lilly which was originally for osteoporosis patients.

The FDA has officially approved Evista for use in breast cancer patients as of late this week, although the drug will now come with a box warning advising patients of a heightened risk for stroke by taking the drug.

I'm not sure -- are some drugs worth the possible benefits when certain side effects can be just as bad as what is trying to be treated?

Eli Lilly's Evista breast cancer drug has seen sharp criticism from womens' groups and more -- and has seen opposition from the FDA as well. The drug, nevertheless, may be approved by an FDA panel soon. What would most likely follow would be official FDA approval, which means the drug would then be free to be marketed and prescribed.

Although Evista was designed for osteoporosis prevention eight years ago, Eli Lilly now wants it used for breast cancer prevention in postmenopausal women. Is this a case of a drug being re-packaged to treat some other condition as a way to make it more "sale-able?"

Who knows. But when drugs meant for one condition are turned into drugs to treat something else, one has to question the motives. Will you?

Diahann Carroll, an actress who started her career back in the 50s, and Oscar nominee who has starred in such TV shows as Dynasty, will be reaching out to older women in an effort to raise breast cancer awareness and the breast cancer risks they face. Carroll, who was diagnosed at the age of 63, spoke with CBS The Early Show's Julie Chen about the shock of being diagnosed with breast cancer when she had no family history for the disease. At the time, she said she was much more concerned about preventing age-related diabetes and heart disease.

According to recent surveys, so are most postmenopausal women. The results of a new Harris Interactive survey of nearly 20,000 women revealed that only 37 percent of women 55 or older are concerned about developing breast cancer as they age. The findings also show that three out of every four women don't know that being over 50 is the greatest risk for developing breast cancer. In fact, most women believe that the greatest risk factors are having a family member with the disease and inherited genetic mutations.

Carroll has been hired by Eli Lilly as the spokesperson for the launch the Strength in Knowing: The Facts and Fiction of Breast Cancer Risk campaign and website created to educate postmenopausal women about the real breast cancer risk factors. In the new fall TV season, Carroll will become a part of Grey's Anatomy. She would not give Chen any details. You can watch The CBS The Early Show interview with Carroll here.
