Functional Medicine
Cancer Prevention
Cancer prevention isn't just avoiding carcinogens. It's optimizing the metabolic, immune, and hormonal environment that determines whether a precancerous cell grows or gets eliminated. We focus on reducing risk through advanced testing, inflammation control, immune optimization, and metabolic health.

Why Conventional Cancer Screening Isn't Prevention
Annual physicals and standard cancer screenings (mammograms, colonoscopies, PSA tests) are detection tools, not prevention tools. They find cancer after it's already formed. By the time a tumor is detectable on imaging, it's been growing for years. Screening saves lives. But it's not prevention.
True cancer prevention means creating an internal environment that's hostile to cancer cell growth. Your immune system kills precancerous cells every day. It only fails when the system is overwhelmed or compromised: chronic inflammation, immune suppression, hormonal imbalance, nutrient deficiency, metabolic dysfunction, toxic burden, and chronic stress all shift the environment in favor of cancer growth.
Functional medicine approaches cancer prevention by optimizing the systems that keep cancer cells in check. This is not alternative medicine. It's proactive metabolic, immune, and hormonal optimization based on your actual lab values and risk factors.

A Proactive Prevention Protocol
We assess your individual cancer risk through detailed testing and family history, then build a prevention protocol targeting your specific vulnerabilities.
- Inflammation control. Chronic inflammation is the single biggest modifiable cancer risk factor. We test inflammatory markers (hs-CRP, homocysteine, insulin) and address sources of chronic inflammation.
- Metabolic optimization. Insulin resistance and metabolic syndrome significantly increase cancer risk. We optimize blood sugar, insulin sensitivity, and metabolic function.
- Immune support. Vitamin D optimization (levels above 50 ng/mL are associated with reduced cancer risk), zinc, selenium, and other immune-modulating nutrients that support cancer cell surveillance.
- Hormone balance. Both excess and deficiency in key hormones influence cancer risk. We optimize levels based on evidence-based ranges, not just avoiding deficiency.
- Toxin reduction. Environmental carcinogens (mold, heavy metals, pesticides) are testable and removable. We identify your toxic burden and support clearance.
- Gut health. The gut microbiome directly influences immune surveillance and inflammation. A healthy microbiome is part of cancer defense.
This is not a replacement for standard cancer screening. It's an addition. You still get your mammograms, colonoscopies, and check-ups. We layer proactive optimization on top of detection.
How Does Functional Medicine Approach Cancer Prevention?
Conventional cancer screening focuses on detection. Mammograms, colonoscopies, PSA tests, and imaging all serve an important purpose: they find cancer after it has already formed. Early detection saves lives. But detection is not the same as prevention.
Functional medicine approaches cancer prevention by optimizing the internal systems that keep precancerous cells in check. Your immune system eliminates abnormal cells every day. The question is whether the environment inside your body supports that process or undermines it.
Six systems matter most for cancer prevention:
1. Inflammation. Chronic inflammation is the single biggest modifiable cancer risk factor. It damages DNA, promotes cell mutation, suppresses immune surveillance, and creates conditions where abnormal cells can survive instead of being cleared. Sources of chronic inflammation include gut dysfunction, food sensitivities, insulin resistance, poor sleep, chronic stress, and environmental toxic burden. All of these are testable and treatable.
2. Metabolic health. Insulin resistance and metabolic syndrome significantly increase cancer risk. Cancer cells are metabolically active and thrive in high-glucose, high-insulin environments. Optimizing blood sugar regulation, insulin sensitivity, and body composition changes the terrain cancer needs to grow.
3. Immune function. Your immune system is your first line of defense against cancer cell formation. Nutrient deficiencies (especially vitamin D, zinc, and selenium), chronic stress, poor sleep, and gut dysfunction all compromise immune surveillance. Optimizing these factors supports the immune system's ability to identify and eliminate abnormal cells before they become tumors.
4. Hormone balance. Both excess and deficiency in key hormones influence cancer risk differently depending on the type of cancer and individual biology. Testing and optimizing hormone levels based on evidence-based ranges (not just avoiding deficiency) is part of a proactive prevention strategy.
5. Toxin burden. Environmental carcinogens like mold, heavy metals, pesticides, and endocrine disruptors accumulate in the body over time. These are testable. Mold exposure, for example, can be identified through urinary mycotoxin testing. Heavy metal burden can be assessed through blood or urine testing. Once identified, targeted protocols support clearance through the body's detoxification pathways.
6. Gut health. The gut microbiome directly influences immune function, inflammation levels, hormone metabolism (through the estrobolome), and toxin clearance. A healthy, diverse microbiome is part of cancer defense. Gut dysfunction contributes to chronic inflammation and impairs the very systems that keep cancer cells in check.
At Med Matrix in South Portland, Maine, Dr. Paul Laband and Dr. Sasha Rose evaluate these systems together rather than in isolation. The goal is not to replace standard cancer screening. It is to layer proactive metabolic, immune, and hormonal optimization on top of detection. You still get your mammograms, colonoscopies, and regular check-ups. We add the testing and interventions that reduce the conditions under which cancer develops.
What Lab Tests Help Detect Cancer Risk Early?
Cancer risk assessment goes beyond the standard physical. The markers below do not diagnose cancer. They identify the modifiable risk factors that functional medicine can address to reduce the likelihood of cancer developing.
- High-sensitivity CRP (hsCRP) and homocysteine. These inflammatory markers indicate the level of chronic inflammation in your body. Persistent elevation signals an environment where DNA damage and immune suppression are more likely.
- Fasting insulin, glucose, and HbA1c. Insulin resistance creates a metabolic environment that favors cancer cell growth. These markers catch metabolic dysfunction years before it progresses to diabetes.
- Vitamin D. Research links vitamin D levels above 50 ng/mL with reduced cancer risk across multiple cancer types. Most conventional labs consider 30 ng/mL "sufficient." Functional medicine targets 50 to 80 ng/mL for optimal immune and cellular function.
- Zinc and selenium. Both minerals support immune cell function and act as cofactors in the body's antioxidant defense systems. Deficiency compromises the immune response to abnormal cell growth.
- Ferritin. Iron status affects cellular energy production and immune function. Both excess and deficiency create problems. Elevated ferritin can be an inflammatory marker in its own right.
- Full thyroid panel. Thyroid dysfunction affects metabolic rate, immune function, and cellular repair processes. An underperforming thyroid slows down the body's maintenance systems.
- Sex hormones (testosterone, estrogen, progesterone). Hormonal imbalances influence cancer risk differently depending on the type. Testing provides a baseline for targeted optimization.
- Toxin burden markers. Urinary mycotoxin panels (for mold exposure), heavy metal testing, and environmental toxin assessments identify carcinogens that may be accumulating in your body.
All of these are included in or available through the initial testing process at Med Matrix. Your provider uses this data alongside your family history, lifestyle, and health goals to build a personalized prevention protocol. For patients who want to go further, we work with your oncologist or primary care doctor to coordinate screening schedules and share results.
If you are looking for advanced lab testing that goes beyond what a standard physical covers, your first visit at Med Matrix includes an 80+ biomarker blood panel and InBody 770 body composition scan.
What Supplements Reduce Cancer Risk?
Supplementation for cancer prevention is not about taking a stack of pills and hoping for the best. It is about identifying specific deficiencies in your labs and correcting them with targeted support. Here are the supplements most commonly recommended based on the research and what our providers see in patient lab work:
Vitamin D. One of the most studied nutrients in cancer prevention. Research links levels above 50 ng/mL with reduced risk for colorectal, breast, prostate, and other cancer types. Most patients in Maine are deficient, especially during winter months when sun exposure drops. Your provider will test your level and dose accordingly. Vitamin D3 paired with K2 is the standard recommendation for optimal absorption and calcium regulation.
Omega-3 fatty acids (EPA and DHA). Reduce chronic inflammation and support immune cell function. Anti-inflammatory effects help create an internal environment less hospitable to cancer cell growth. Your provider may recommend 2,000 mg or more per day depending on your inflammatory markers.
Selenium. An essential trace mineral that supports antioxidant defense systems and immune function. Selenium deficiency is associated with increased cancer risk across multiple studies. Supplementation is guided by lab testing to avoid excess.
Zinc. Supports immune cell production and function. Low zinc is common in patients with chronic stress, gut issues, or poor dietary intake. Testing ensures you are supplementing appropriately rather than guessing.
Curcumin (turmeric extract). One of the most researched natural anti-inflammatory compounds. Research suggests effects on multiple inflammatory pathways relevant to cancer prevention. Bioavailability matters: your provider will recommend a form that your body can actually absorb.
Probiotics and prebiotic fiber. Support a healthy, diverse gut microbiome. The microbiome directly influences immune surveillance, inflammation levels, and hormone metabolism. A well-functioning gut is part of the body's cancer defense system.
NAC (N-acetyl cysteine). Supports glutathione production, the body's primary antioxidant. Particularly relevant for patients with environmental toxic burden from mold, heavy metals, or chemical exposures.
The right supplement protocol depends entirely on your labs. A man with optimal vitamin D but low selenium needs a different approach than a woman with high inflammatory markers and low omega-3 levels. That is why testing comes first at Med Matrix. We never recommend supplements based on generic protocols.
Cancer Prevention and Your Family History
Family history of cancer changes the conversation, but it does not determine the outcome. Genetic predisposition means your risk is elevated, not that cancer is inevitable. Genes load the gun. Environment and lifestyle pull the trigger.
If you have a family history of cancer (a parent, sibling, or grandparent diagnosed with cancer), proactive prevention becomes more important, not less. The modifiable factors that determine whether genetic risk becomes actual disease are the same ones functional medicine addresses:
- Inflammation levels. Chronic inflammation activates pathways that can trigger gene expression for cancer growth. Reducing inflammation through diet, gut health, stress management, and targeted supplementation shifts the environment away from cancer-favorable conditions.
- Metabolic function. Insulin resistance and metabolic syndrome create conditions that favor abnormal cell growth. Optimizing blood sugar, insulin sensitivity, and body composition reduces this risk.
- Toxic burden. Environmental carcinogens interact with genetic vulnerabilities. Identifying and reducing exposure to mold, heavy metals, pesticides, and endocrine disruptors is especially important for patients with cancer in their family history.
- Immune health. A strong immune system catches and eliminates precancerous cells before they can establish themselves. Nutrient optimization (vitamin D, zinc, selenium), sleep quality, and stress management all support immune surveillance.
- Hormone balance. For patients with family history of hormone-sensitive cancers (breast, prostate, ovarian), monitoring and optimizing hormone levels becomes part of an ongoing prevention strategy.
At Med Matrix, your providers (Dr. Paul Laband and Dr. Sasha Rose) will review your family history alongside your lab work, lifestyle factors, and environmental exposures. The goal is to control everything that is controllable so your genetic risk stays dormant.
This is not alternative medicine. It is evidence-based prevention layered on top of the standard screening your oncologist or primary care doctor recommends. We coordinate with your existing care team. We do not replace them.
Common Symptoms We See
- Family history of cancer (parent, sibling, or grandparent)
- Chronic fatigue that does not improve with rest
- Unexplained weight changes (gain or loss)
- Chronic inflammation or elevated inflammatory markers on previous labs
- Known environmental exposures (mold, heavy metals, pesticides)
- Insulin resistance, pre-diabetes, or metabolic syndrome diagnosis
- Frequent illness or slow recovery from infections
- Chronic stress with poor sleep quality
- Digestive issues or known gut dysfunction
- Feeling that your standard physical does not look at the full picture
What We Test for This Condition
High-Sensitivity CRP (hsCRP)
Measures chronic inflammation, the single biggest modifiable cancer risk factor. Persistent elevation signals an environment where DNA damage is more likely.

Lean
Lean is recovering from breast cancer and also undergoing treatment for Lyme disease. She previously traveled to Rhode Island and Portsmouth, NH to access ozone therapy, so finding Med Matrix in South Portland was a major convenience win. She reports improved focus, reduced brain fog, better energy, and enhanced recovery, and has referred her husband, daughter, and friends to the clinic.
“I was thrilled to be able to incorporate it more consistently into my recovery program. It's just so convenient to have it so nearby.”

Dean
Dean is an organic farmer in his later years who had avoided conventional medicine for over 15 years. After going through a difficult divorce that left him broken, fatigued, and emotionally low, he found Med Matrix online and gave functional medicine a try. Testing revealed low testosterone and nutritional deficiencies. TRT and a supporting medication turned his health and emotional life around. He is now happy, energized, losing weight in a healthy way, and views Med Matrix as part of his long-term health plan.
“I realized that I wasn't happy for a long, long time when I'm actually happy. So I'd say that's the biggest thing.”

FAQ
Cancer Prevention FAQ
No. This is prevention, not treatment. We do not treat active cancer. We optimize metabolic, immune, and hormonal health to reduce the risk of cancer developing. If you have an active cancer diagnosis, work with your oncologist. We can support your overall health alongside conventional treatment with your oncologist's knowledge.
Family history increases risk but doesn't determine outcome. Genetic predisposition needs environmental triggers to express. We focus on controlling the modifiable factors (inflammation, metabolic health, toxin exposure, immune function) that determine whether genetic risk becomes actual disease.
We test inflammatory markers, metabolic markers (insulin, glucose, HbA1c), hormone levels, nutrient status (especially vitamin D, selenium, zinc), and toxic burden. This identifies the modifiable risk factors we can address through targeted protocols.
