According to the Centers for Disease Control and Prevention (CDC), more than 50,000 Americans die from colorectal cancer each year.  In the U.S., colorectal cancer (CRC) is the third most common cancer diagnosed among men and women and the second leading cause of death from cancer. However, through regular screenings (including colonoscopies) many of these deaths can be prevented.

A colonoscopy, an endoscopic  procedure that examines the entire length of the large intestine, is recommended every 10 years for CRC screening in average-risk adults beginning at age 50.    A colonoscopy may be recommended before age 50 in individuals that are at higher-risk than average for developing CRC.  Patients who are at increased risk for CRC development include:
  • Patients with a personal history of CRC
  • Patients with a family history of CRC or polyps (precursors to cancer)
  • Patients with a personal history of inflammatory bowel disease
  • Patients with a family history of hereditary non-polyposis CRC (Lynch Syndrome) or familial adenomatous polyposis (FAP)
Routine colonoscopy screening can help prevent many cases of CRC by detecting and removing polyps before they have the chance to turn into cancer.  Screening colonoscopy can also help find CRC early, and survival is significantly better when CRC is detected in early stage before it has spread.

In addition to regular colonoscopy screenings, a patient can also make lifestyle changes to lower their risk of developing CRC.  These lifestyle changes may include staying physically active and maintaining a healthy weight, limiting alcohol consumption, eating more fruits and vegetables and less foods higher in fat,  and avoiding tobacco use.
