9 Underrated Things That May Lower Your Cancer Risk

Most cancer prevention conversations sound the same... Don't smoke. Exercise. Eat vegetables. Get your screenings. And while none of that is wrong — it's incomplete. Because there is a growing body of research pointing to everyday habits, foods, and environmental inputs that quietly and consistently show up as protective against cancer — and almost nobody is talking about them.

9 UNDERRATED PRACTICES FOR CANCER PREVENTION 

ASPIRIN (WHEN APPROPRIATE)

Aspirin has been studied for decades as more than a pain reliever. It lowers systemic inflammation, prevents lipolysis (fat breakdown that can feed cancer cells), blocks COX enzymes involved in tumor promotion, helps restore healthy glucose oxidation, and has been shown to inhibit metastasis. Research links regular aspirin use to lower risk of colorectal, breast, brain, ovarian, prostate, and other cancers. (PMID: 39923320)

Important note: Aspirin is not appropriate for everyone. Always discuss with your healthcare provider before using it regularly. 

COFFEE

Your morning cup may be doing more than waking you up. Coffee is rich in antioxidants, supports liver detoxification pathways, and has been linked in multiple studies to lower risk of thyroid, liver, endometrial, and colorectal cancers. (PMID: 36769029)

The key is quality — organic, low-mold coffee without inflammatory creamers or excess sugar. 

SUNLIGHT

As I shared in my last email — this one deserves repeating. UVB light from the sun boosts vitamin D, which regulates immune cells and cancer-protective pathways throughout the body. Infrared light from the sun also directly enhances mitochondrial function and cellular repair.

Consistent sun exposure is linked to lower incidence of breast, brain, colon, bladder, pancreatic, stomach, kidney, and non-Hodgkin's lymphoma. (PMID: 38794688)

The sun is not your enemy. Avoidance is.

CALCIUM

A 2025 study found that every 300mg per day of calcium intake was associated with a 17% lower risk of colorectal cancer. Predicted milk consumption of just 200g per day was associated with a 40% reduction in colorectal and colon cancer risk — and a remarkable 51% reduction in rectal cancer risk. (PMID: 39779669)

Not all dairy is created equal. Grass-fed, full-fat, and low-processed options are the most nutrient-dense.

WARM BATHS & SAUNA

Cancer cells are uniquely sensitive to heat — which is why hyperthermia is already used as an adjunct cancer therapy in clinical settings. Regular heat exposure through baths or sauna induces mild hyperthermia, improves immune function, promotes detoxification through sweat, and reduces systemic inflammation.

This is one of the most accessible and underutilized tools available. Even a warm bath 3–4 times per week has measurable physiological benefit.

AVOIDING ARTIFICIAL LIGHT AT NIGHT

This one is rarely discussed in cancer conversations — but the research is striking. A 2016 study concluded that "artificial light at night is significantly correlated for all forms of cancer as well as lung, breast, colorectal, and prostate cancers individually." (PMID: 27892680)

Artificial light disrupts melatonin — one of the body's most powerful antioxidants and immune regulators. Simple protective steps include using candles or incandescent bulbs in the evening, sleeping close to sunset when possible, and reducing screen exposure after dark.

NASAL BREATHING

Most people breathe through their mouths without thinking twice. But nasal breathing supports CO2 retention, which improves oxygen delivery to tissues through a mechanism called the Bohr effect.

This matters for cancer because cancer cells preferentially grow in low-oxygen environments. Maintaining healthy oxygen levels in tissues through nasal breathing may help the body maintain conditions that are hostile to cancer cell proliferation.

COCONUT OIL

Coconut oil is rich in lauric acid — a medium-chain fatty acid that is rapidly converted into energy by the liver rather than stored as fat. It is also exceptionally stable at high heat, making it one of the safest oils for cooking.

In 2022, researchers found that lower levels of lauric acid in the body may be associated with a higher risk of breast cancer. (PMID: 36558514)

Swapping inflammatory seed oils (canola, soybean, sunflower) for coconut oil or grass-fed butter is a simple, meaningful change.

SUNRISE AND SUNSET

The light at sunrise and sunset is uniquely rich in infrared and red wavelengths — the same wavelengths used in red light therapy, which is gaining significant research attention for its ability to support mitochondrial function and cellular repair.

Your mitochondria are your cells' energy generators. Healthy mitochondria are foundational to immune function, metabolic health, and the body's ability to identify and eliminate abnormal cells before they become a problem.

Spending even 5–10 minutes outside at sunrise or sunset costs nothing and delivers direct cellular benefit.

THE BIGGER PICTURE

None of these practices are dramatic. None of them require a prescription or an expensive protocol. What they have in common is that they work with the body's natural design — supporting the immune system, reducing inflammation, optimizing mitochondrial function, and keeping the internal environment less hospitable to disease.

TAKE ACTION

If you want to understand where your own inflammatory markers, vitamin D levels, metabolic function, and other root cause factors stand right now — that is exactly what I help people investigate and address.
