People can lower their risk of developing colorectal cancer by managing the risk factors that they can control, such as diet.

Youth Pastor Brad Branson has heard about the study linking red meat to colon cancer before -- but has it affected his eating habits? "I think to some degree, I've cut back a little bit maybe even then what I did then when I was growing up, or at least eating better qualities of beef."

Cutting back is probably a good thing. Dr. Asif Choudhury says prevention and good health is really all about moderation and proper nutrition. "Low fiber eating and high red meat and low cooked meat, those are the main important for patients might have cancer to develop colon polyps and then colon cancer."

One recent study is not saying exclusively that red meat causes colorectal cancer, rather, it found that the chance of developing it was a third higher in people who regularly ate more than two portions of red or processed meat a day, compared to someone who ate less than one portion a week.

Brad says, "I still love a good steak, but I haven't made that choice to give it up or anything."

Dr. Choudhury says you don't have to give it up altogether, but you do need to remember to eat it in moderation and the other important thing is to add fiber to your diet. "High fiber is that cereals, bran, fruits, vegetables. Usually fruits and vegetables are the fibers."

Health experts estimate that about 70 percent of colorectal cancers can be prevented by changes in diet and nutrition.

A diet rich in fat, animal protein and refined carbohydrates with low fiber intake and a lack of exercise are all risk factors for colorectal cancer.
