At least 6 out of every 10 deaths from colorectal cancer could be prevented if all men and women aged 50 years or older were screened routinely.
Precancerous polyps (abnormal growths) can be present in the colon for years before invasive cancer develops. They may not cause any symptoms. Colorectal cancer screening can find precancerous polyps so they can be removed before they turn into cancer. In this way, colorectal cancer is prevented. Screening can also find colorectal cancer early, when there is a greater chance that treatment will be most effective and lead to a cure.
Some studies suggest that people may reduce their risk of developing colorectal cancer by increasing physical activity, eating fruits and vegetables, limiting alcohol consumption, and avoiding tobacco.
