Facts on colorectal cancer
Regular screenings are recommended

"Colorectal cancer is one of the most frequently diagnosed cancers in the U.S.," said Dr. James Yoo, assistant professor of surgery at the David Geffen School of Medicine at UCLA. "Fortunately, colorectal cancer can be largely prevented with early screening or cured with early detection."

UCLA's medical department offers tips to lower one's risk.

•A person at normal risk should receive regular colorectal cancer screenings beginning at age 50.

•A person at higher risk due to a personal or family history of colorectal cancer, other cancers or inflammatory bowel disease should talk to a doctor about screenings before age 50.

•Eat between 25 and 30 grams of fiber each day from fruits, vegetables, whole grain breads and cereals, nuts and beans.

•Eat foods with folate, such as leafy green vegetables.

•Eat a low fat diet. Colorectal cancer has been associated with diets high in saturated fat.

•Drink alcohol in moderation and don't smoke. Alcohol and tobacco in combination are linked to colorectal cancer and other gastrointestinal cancers.

•Exercise for at least 20 minutes three to four days a week. Moderate exercise such as walking, gardening or climbing stairs may help reduce risk.

•Report to a doctor any persistent symptoms such as blood in the stool, change in bowel habits, weight loss, abdominal pains or other gastrointestinal complaints.

•Maintain a healthy weight. For more information, visit www.cancer.org.
