Cancer Prevention Through a Healthy Lifestyle
Many of these recommendations are supported by research in metabolic health, inflammation, and cancer risk reduction. Preventing cancer involves reducing risk factors and adopting healthier lifestyle choices. While no strategy guarantees complete prevention, evidence suggests that lifestyle and metabolic health play a significant role in cancer risk.
Below are key strategies that may help reduce cancer risk and support overall health.
1. Healthy Diet: Eat
.Eliminate processed foods, seed oils, and limit your intake of sugar and alcohol. A diet rich in whole, nutrient-dense foods may help reduce cancer risk. Focus on:
• High-quality proteins
• Vegetables and low-glycemic fruits
• Fiber-rich foods
• Healthy fats
Consider limiting:
• Ultra-processed foods
• Refined sugars
• Excess alcohol
• Highly processed seed oils
These dietary choices may help reduce inflammation, support metabolic health, and strengthen immune function.
2. Maintain a Healthy Weight.
Obesity can impair your immune system by promoting chronic inflammation. Aim for a balanced and regular exercise regimen to maintain a healthy BMI. Excess weight is associated with chronic inflammation and metabolic dysfunction, both of which may increase cancer risk.
Obesity has been linked to several cancers, including:
• Breast cancer
• Colon cancer
• Kidney cancer
• Pancreatic cancer
Maintaining a healthy weight through nutrition and physical activity may help lower risk.
3. Physical Activity.
Exercise helps regulate hormones like cortisol (inflammation-causing), boosts your immunity, helps maintain a healthy weight, and reduces inflammation by improving blood flow. Regular physical activity supports metabolic health and immune function.
General recommendations include:
• 150 minutes of moderate aerobic activity per week (walking, cycling)
• 75 minutes of vigorous activity (running, swimming)
Exercise may:
• Reduce inflammation
• Improve immune function
• Support hormone balance
• Improve mitochondrial function
4. Avoid carcinogens.
Reducing exposure to environmental toxins may help lower cancer risk. These may include:
• Asbestos
• Radon
• Heavy metals
• Industrial chemicals
• Air pollution
When possible, consider testing your home for radon and limiting exposure to harmful chemicals.
5. Manage stress and sleep
Chronic stress and poor sleep may impair immune function and increase inflammation.
Healthy strategies include:
• Regular exercise
• Prayer or meditation
• Stress management techniques
• Maintaining a consistent sleep schedule
Aim for 7–9 hours of sleep per night.
6. Avoid Tobacco
Smoking and tobacco exposure are among the strongest known cancer risk factors.
Avoid:
• Smoking
• Vaping
• Secondhand smoke
Quitting tobacco use is one of the most effective ways to reduce cancer risk.
7. Water Purification
We have a water crisis, which extends far beyond Flint, Michigan, with over 200 million Americans exposed to chemical contaminants, including lead, PFAS, and microplastics. Chlorination byproducts in treated water may increase cancer risks, while agricultural runoff containing atrazine can disrupt hormonal development at low exposure levels. Water quality is an important but often overlooked factor in long-term health.
Potential contaminants include:
• PFAS ("forever chemicals")
• Heavy metals (lead, mercury)
• Agricultural runoff
• Chlorination byproducts
Consider:
• Water filtration systems
• Testing home water sources
• Avoiding plastic water containers when possible
8. Sousop
Benefits for fighting cancer, rich in antioxidants, help neutralise harmful free radicals that contribute to cancer. Soursop is a fruit rich in antioxidants and plant compounds called acetogenins, which have shown potential anticancer activity in laboratory studies.
Potential benefits:
• Antioxidant support
• Immune support
• Anti-inflammatory properties
However, soursop is relatively high in carbohydrates, and for this reason, I do not typically recommend it for active cancer treatment in patients following metabolic approaches.
9. Cancer is affected by lifestyle
By not exercising, being under stress, having poor sleep, and eating ultra-processed food (sometimes food-like substances). Our bodies become increasingly less capable of utilizing oxygen to generate energy. Cells resort to fermentation, when cells switch from oxygen to glucose (a sugar) and glutamine (an amino acid) to generate energy, they become cancer cells. One potential strategy is to reduce the fuel sources that cancer cells rely on.. Lifestyle factors can influence metabolic health and mitochondrial function.
Poor diet, inactivity, stress, and poor sleep may contribute to:
• Insulin resistance
• Inflammation
• Mitochondrial dysfunction
These metabolic changes may create conditions that support cancer development.
Improving metabolic health may help reduce risk.
10. Get your biomarkers checked
The purpose is to look for early signs of future disease. This often starts with insulin resistance, leading to inflammation and eventually mitochondrial dysfunction, laying the groundwork for cancer. Early metabolic changes often occur before disease develops.
Testing may include:
• Insulin
• Glucose
• Inflammatory markers
• Metabolic markers
Identifying abnormalities early allows for lifestyle changes that may reduce long-term risk.
To be evaluated, you can schedule a consultation to review testing and develop a personalized prevention plan.
11. Early Cancer screening
Once you have decided to ‘‘screen or not,” the question is then what type? We don’t want to be harmed by rather invasive, harmful procedures (colonoscopy with bowel perforation) or by ionizing radiation (virtual CT colonoscopy; repeated mammography, etc.) Check out these alternative and safer screening tests: Cancer screening is an important part of prevention. The choice of screening methods should consider:
• Individual risk
• Benefits and risks
• Frequency of testing
Some patients may wish to explore alternative or lower-radiation screening options when appropriate.
