Colorectal Cancer Prevention: Evidence-Based Strategies

by Jon Scaccia October 19, 2023

Colorectal cancer, affecting the colon and rectum, is one of the most common cancers worldwide. Fortunately, several evidence-based strategies can help in its prevention. While no method guarantees complete protection, combining multiple strategies can significantly reduce the risk.

1. Regular Screening

Why it’s important: Screening can detect precancerous polyps, which can be removed before they become cancerous. It can also detect colorectal cancer early when treatment is most effective.

Recommendations: Consider regular screenings like colonoscopies or fecal occult blood tests starting at age 45 or 50 (depending on individual risk factors and guidelines).

2. Diet and Nutrition

Why it’s important: What you eat can influence the risk of developing colorectal cancer.

Recommendations:

• Increase Fiber Intake: Whole grains, fruits, and vegetables are rich in fiber which may help protect against colorectal cancer.
• Limit Red and Processed Meats: High consumption has been linked to an increased risk.
• Consume Calcium and Vitamin D: Some studies suggest they might help protect against colorectal cancer.

3. Physical Activity

Why it’s important: Regular physical activity can help reduce the risk of colorectal cancer.

Recommendations: Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity weekly. Personal note: what has helped me as I go into mid-middle age is walking. It’s hard for me to get up and get the motivation to go for a 6-mile run at 4:45. It’s much easier to just start walking@

4. Avoid Tobacco and Limit Alcohol

Why it’s important: Both tobacco and excessive alcohol consumption are risk factors for colorectal cancer.

Recommendations: If you smoke, seek help to quit. Limit alcohol consumption to moderate levels: up to one drink per day for women and up to two drinks per day for men.

5. Consider Aspirin

Why it’s important: Some studies have shown that taking aspirin can reduce the risk of colorectal cancer.

Recommendations: Discuss with your doctor before starting aspirin for cancer prevention, as it’s not suitable for everyone and can have side effects.

6. Be Aware of Personal and Family History

Why it’s important: Individuals with a family history or certain genetic mutations have a higher risk.

Recommendations: If you have a family history, consider genetic counseling and possibly earlier and more frequent screenings.

Conclusion

Preventing colorectal cancer involves a combination of regular screenings and lifestyle choices. Stay informed and proactive can significantly reduce your risk and promote overall health.
