Women are less likely than men to get bladder cancer — but we also are less likely to survive if we do get it, according to the National Institutes of Health. Encouraging news from a recent study: Compared with women who had the lowest blood levels of the mineral selenium, those with the highest levels were 34% less likely to get bladder cancer.

Bottom line: Further research is needed before selenium supplements could be recommended for bladder cancer prevention, but results of several studies are promising. Meanwhile, selenium-rich foods — including nuts, seafood and whole wheat — can be a healthful part of your diet.
