Another expert added that even though beta blockers might not help prevent colon tumors, people have other means of doing so.
"Men and women at average risk should start getting screened at age 50," said Dr. Mark Pochapin, director of the division of gastroenterology at NYU Langone Medical Center in New York City. "Those with certain risk factors, such as a family history of colorectal polyps or cancer, should talk to their doctors about screening at a younger age."
Pochapin also added that "lifestyle modifications -- such as quitting smoking, avoiding excess intake of red or processed meats, ensuring adequate vitamin D intake, and maintaining a healthy body weight and regular exercise -- can be very beneficial in reducing one's risk for colorectal cancer."
The U.S. National Cancer Institute has more about colorectal cancer risk factors and prevention.
