Is there a way to clean out the colon to prevent colon cancer?

First and foremost, Dr. Oz makes the audience member asking this question promise that he will get a colonoscopy. The next thing Dr. Oz says he can do is clean out his colon by eating more fiber. "Here's the deal," he says. The best way to clean the colon is not through these enemas that folks sometimes get."

Dr. Oz explains that most men only get about seven grams of fiber in their current diet—but need to be getting 35 grams every day. "The fiber washes out all the junk so it doesn't lay in the colon, irritating the cells and becoming toxic by rotting in there," Dr. Oz says.

Aside from getting more fiber, Dr. Oz recommends adding more leafy green vegetables and broccoli to your diet. "Those kinds of foods are incredibly powerful at reducing the chance of cancer," he says.

The last component is aspirin, which Dr. Oz says helps prevent colon cancer without causing heart attacks, like some drugs did in the past that had to be taken off the market. "So aspirin, leafy green vegetables, stuff like broccoli, and get a colonoscopy because you can save your life."
