Overview
Most colorectal cancers should be preventable through surveillance, improved lifestyle and nutrition, and other techniques such as increased intake of vitamin B6 and aspirin.
Colorectal Cancer Primary Prevention
Surveillance
The most common indicator of high risk is a first-degree relative with colorectal cancer[1].
- If the first-degree relative was diagnosed with CRC before 50 years of age
- The individual should be suspected of a hereditary syndrome and referred to a specialist
- The specialist will obtain a complete family history, consider genetic counseling and testing, and determine appropriate timing for endoscopic surveillance
- If a first-degree relative was diagnosed with CRC at 50 years of age or older
- The lifetime risk of CRC nearly doubles among his or her family members
- Colonoscopy is the preferred screening test for these individuals
- Screening should be initiated either when they are 40 years old or when they are 10 years younger than the age at which the family member received the diagnosis, whichever comes first
- If the individual is diagnosed with chronic ulcerative colitis or colitis due to Crohn's disease
- There is an increased risk for CRC and the individual should undergo surveillance with colonoscopy, generally beginning 8 to 10 years after the diagnosis
Lifestyle & Nutrition
- A healthy body weight
- Active lifestyle[2]
- A healthy diet - a high intake of dietary fiber from eating fruits, vegetables, cereals, and other high fiber food products) and a low intake of fat and red meat (from eating fruits, vegetables, cereals, and other high fiber food products)[3]
- Reduction of alcohol and cigarette smoking
Other
- Increased intake of vitamin B6 (pyridoxine) intake[4]
- increased intake of dietary or supplemental calcium[5]
- Increased intake of Vitamin D and its metabolites[6]
- Increased intake of dietary magnesium[7]
- Increased intake of omega 3 fatty acids[8]
- Aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs)[9]
- Postmenopausal hormone therapy (both combined estrogen plus progestin and unopposed estrogen)- not recommended for chemoprevention of colon cancer in women because of the associated long-term risks of therapy[10]
