Selenium may decrease ovarian cancer in African-American women

Doctors were especially interested to find a selenium benefit because of the low chances of survival. 

In this study of African-American women, doctors compared the diets of 406 women with ovarian cancer (OC) to 632 women of similar age and geographic location without OC. Women who took selenium supplements of more than 20 mcg per day were 30 percent less likely to develop OC compared to women who did not take supplements.

Among women smokers, those who took selenium supplements were 87 percent less likely to develop OC than those who didn’t take selenium supplements. The benefit appeared only in women who took selenium supplements, and not in those who only got selenium from diet. Doctors said that to their knowledge, this is the first study to find a potential link between antioxidants like selenium and reducing OC in African-American women.
