Fiber Nothing could be less glamorous than fiber, which is, after all, just the indigestible part of fruits, vegetables and grain. But over the past 20 years, researchers have amassed an impressive array of evidence that fiber helps prevent colon cancer. For more fiber, eat high fiber cereal, bran flakes, rye crisp crackers, popcorn, toasted wheat germ, granola, high-fiber bread and beans.

Colorectal cancer is an equal-opportunity killer. About 65,900 women develop colorectal cancer annually. Colorectal cancer is one of the top three cancer killers of women, along with lung cancer and breast cancer. Colorectal cancer kills 27,500 twice as many women as ovarian cancer. That women die at all of colorectal cancer is tragic, because when caught early, it is a very curable disease.
