12 Strategies To Help You Reduce the Risk of Bowel Cancer

What is Bowel Cancer?

Bowel cancer, also known as colorectal cancer or colon cancer, is a disease that affects the large bowel (which includes both the colon and the rectum). It typically begins when cells in the bowel lining grow abnormally, forming small growths called polyps. While most polyps are not cancerous, over several years, some can change and become malignant.

This condition is the third most common cancer diagnosed worldwide. In Australia, Cancer Council Australia highlights it as a leading cause of cancer-related death. However, it is also one of the most treatable cancers because it often develops slowly and can be caught early through regular screening.

Main Symptoms and Causes

Symptoms:

• Look for hidden blood in the stool.
• Persistent changes in toilet habits.
• Unexplained weight loss.

Risk Factors: While ageing is a factor, many risks are linked to long-term irritation of the bowel wall due to diet, lack of exercise, and environmental factors.

Genetics: About 5 to 10% of cases are linked to inherited medical conditions such as Lynch syndrome or Familial Adenomatous Polyposis.

Risk Reduction vs. Early Detection: Why the Distinction Matters

Before we dive into the strategies, it is vital to understand how we approach bowel health.

Early Detection of Bowel Cancer

‍This involves finding and removing premalignant lesions. When you undergo a screening test, doctors can find and remove polyps before they have the chance to become cancerous. This is a clinical intervention that can effectively stop cancer from developing.

Risk Reduction

‍This involves addressing modifiable risk factors by optimising your internal environment. While staying physically active and maintaining a healthy weight significantly lowers the statistical probability of developing colon cancer, lifestyle changes are most effective when paired with precise clinical oversight.

At Everlab, we bridge the gap between lifestyle habits and clinical prevention through deep-health profiling. By monitoring specific inflammatory biomarkers and utilising advanced laboratory screenings, we can identify subtle metabolic shifts. Our comprehensive approach allows for the identification of genetic indicators, ensuring that your health plan is backed by rigorous data and sophisticated diagnostic tools available in modern medicine.

While we cannot change our age or medical history, we can control our lifestyle factors. Understanding this distinction empowers you to use both medical screening and daily habits to protect your longevity.

Key Strategies to Reduce Your Bowel Cancer Risk

To help you navigate your health journey, here are the most effective strategies to keep your large bowel healthy.

1. Prioritize Dietary Fibre from Whole Sources

Dietary fibre is perhaps your greatest ally. It acts as a natural cleanser, moving waste through the large bowel efficiently.

• Eat wholegrains: Swap white bread for whole grains and white rice for brown rice.
• Legume power: Incorporate lentils, chickpeas, and beans into at least three meals a week.
• Fruit with skin: Eat the skins of apples and pears where the fibre is concentrated.
• Veggie volume: Aim for five serves of vegetables daily to provide "bulk" for your digestive system.

2. Eliminate Processed Meat

The World Health Organization has classified processed meat (like bacon, ham, salami, and hot dogs) as a Group 1 carcinogen.

• Avoid nitrates: The chemicals used to preserve these meats can damage the bowel wall.
• Swap the deli meats: Use fresh cooked chicken or avocado in sandwiches instead of ham.
• Check labels: Many snacks contain processed ingredients that contribute to bowel cancer risk.

3. Limit Red Meat Consumption

While lean red meat provides essential nutrients like iron and B12, eating high amounts of red meat is linked to colon cancer.

• Portion control: Limit beef, lamb, and pork to no more than three 65g to 100g serves per week.
• Cooking methods: Avoid charring meat over high flames, as this creates harmful chemicals.
• Meatless Mondays: Adopt plant-based days to reduce your total weekly intake.

4. Maintain a Healthy Body Weight

Excess body fat, particularly around the midsection, can cause chronic inflammation which may fuel cancer risk.

• Maintain a healthy weight: Staying within a healthy weight range is a key modifiable risk factor.
• Avoid rapid weight gain: Consistent, stable weight is better for metabolic health.
• Routine testing: At Everlab, we can measure visceral fat and metabolic markers to see how your body composition is impacting your health.

5. Be Consistently Physically Active

Being physically active is a powerful way to lower colon cancer risk. Exercise reduces inflammation and improves insulin sensitivity.

• Move daily: Aim for at least 30 minutes of moderate physical activity on most days.
• Reduce sitting time: Stand up and move every hour to keep the digestive system stimulated.
• Strength training: Building muscle helps regulate blood sugar, which is a factor in metabolic health.

6. Limit or Avoid Alcohol

Drinking alcohol is a documented risk factor. When the body processes alcohol, it creates substances that can irritate and damage the cells of the gut.

• Lower the frequency: Your risk increases with the amount of alcohol consumed.
• Choose water or soda: Replace alcoholic drinks with sparkling water and lime.
• Dry months: Take extended breaks from alcohol to allow the bowel lining to recover.

7. Quit Smoking

Tobacco smoke contains thousands of chemicals that enter the bloodstream and the digestive tract.

• Stop the damage: To protect your bowel health, it is essential to quit smoking.
• Avoid secondhand smoke: Passive inhalation can also impact your health risks.
• Long-term health: Quitting also reduces the risk of heart disease, which often coexists with cancer risks.

8. Increase Calcium and Dairy Intake

There is evidence from prospective studies that dairy foods may have a protective effect.

• Low fat milk and yoghurt: These provide calcium, which may bind to certain harmful acids in the gut.
• Calcium supplements: If you avoid dairy, talk to a doctor about supplements, though a balanced diet is preferred.
• Vitamin D: Ensure adequate sun exposure or supplementation to help calcium absorption.

9. Be Aware of Medical and Family History

Your medical history and family history dictate how proactive you should be with screening.

• Know your relatives: A strong family history of bowel conditions or cancer means you should start screening earlier.
• Genetic conditions: If you have Lynch syndrome, your risk of bowel cancer is significantly higher, requiring specialised care.
• Talk to a specialist: Map out your family tree to identify these known risk factors.

10. Engage in Regular Screening Tests

Bowel cancer screening is the most effective tool for early detection.

• Stool tests: These look for hidden blood (FOBT) and should be done every two years for those aged 50 to 74.
• Colonoscopy: This is a critical and effective exam for identifying potential issues with a high level of accuracy. It allows for the detection and removal of polyps before they develop further.
• Don't wait for symptoms: Most bowel cancer cases are easier to treat when found through screening before symptoms appear.

11. Limit Ultra-Processed Foods

Beyond meat, many processed foods are low in nutrients and high in additives that can disturb the gut microbiome.

• Eat whole foods: Prioritise "one-ingredient" foods like vegetables, nuts, and seeds.
• Gut health: A healthy microbiome helps protect the bowel lining from inflammation.

12. Consider Preventive Strategies (Under Medical Guidance)

For some individuals at higher risk, certain medications may be recommended by a doctor as part of a risk-reduction plan.

• Consultation is key: Never start a medical regimen without a full review of your specific medical conditions with a qualified health professional.
