Colorectal cancer is the third-leading cause of cancer in The United States. As part of Colorectal Cancer Awareness Month in March, Dr Vi Chiu, director of gastrointestinal oncology and molecular precision programs at Cedars-Sinai’s The Angeles Clinic, outlines six ways to reduce your risk of colorectal cancer.
Get screened. When detected early, colorectal cancer is highly treatable. Adults at average risk should begin screening at age 45; those with first-degree relatives who have had colorectal cancer should begin at age 40. Colonoscopy is “the gold standard for detecting precancerous growths.” Diet. Diets rich in fruits, vegetables and whole grains are associated with a lower risk of colon or rectal cancer. Eat only small amounts of beef, pork and lamb, and fewer processed meats. Adequate vitamin D intake is also important. Get active. Exercise could reduce the risk of colorectal cancer by reducing inflammation in the body and boosting the immune system.
Watch your weight. Being overweight or obese increases the risk of colorectal cancer. Avoid or limit alcohol. “Alcohol can cause intestinal damage. It is a toxin whose byproduct can damage DNA. The gut may develop inflammation, and the gut immunity is weakened. This can lead to colorectal cancer development,” Dr Chiu said. Limit alcohol to no more than one drink per day. Don’t smoke. A 2020 study found that smokers had a 59% higher risk of colorectal cancer; former smokers had a 19% higher risk. People who stopped smoking more than 20 years ago did not have an increased risk.
