Lifestyle over genes: Cancer prevention shifts focus to diet, immunity and non-invasive screening

  • Cellular dysfunction shaped by inflammation, diet and environment is the root cause of cancer. Personal choices, such as smoking and obesity, have a significant impact on cancer risk.
  • Obesity is a significant risk factor for cancer. Excess weight creates a fertile soil for tumor growth, increasing the risk of breast, colon and pancreatic cancers. Insulin spikes fuel cancer growth, with women facing a higher risk of breast cancer with higher BMI. Obesity weakens the immune system, allowing dormant cancers to reawaken.
  • Therapies like CAR-T cell therapy reprogram the body’s immune system to target tumors without the collateral damage of traditional methods. The goal is to restore balance and strengthen the immune system, not just to kill cancer cells.
  • Ancient viral DNA, though defanged by evolution, may resurface in immune-compromised states, driving cancer and autoimmune disorders. Emerging research links retroviruses to conditions like chronic fatigue syndrome and other autoimmune disorders.
  • Diet, regular exercise, stress management and non-invasive screening are key components of a cancer-fighting lifestyle.
For decades, cancer was seen as a war against rogue genes. But new research flips that narrative, emphasizing lifestyle’s dominant role. Medical professionals like Dr. Jason Fung, author of The Cancer Code, argue cancers arise from cellular dysfunction shaped by inflammation, diet and environment. This shift redefines prevention—from genetic inevitability to actionable changes. The American Cancer Society reports 19.3% of U.S. cancers stem from cigarette smoke alone, while obesity drives 7.6%—proof that personal choices can profoundly sway outcomes. “Cancer is a breakdown in cellular cooperation, often triggered by chronic stressors humans can mitigate,” Fung told Vital Signs. Yet not all advocates endorse mainstream approaches. Dr. Galina Migalka, a vocal critic of chemotherapy’s risks, highlights alternative tools like thermography—a radiation-free scan detecting inflammation—to address cancer’s root causes. “Health education, not radiation, is key,” she argues, referencing case studies where plant-based diets shrank tumors without invasive treatments.

Obesity as a catalyst: How insulin fuels tumors

Excess weight fuels cancer by creating a “fertile soil” for tumor growth. The International Agency for Research on Cancer notes obese individuals face heightened risks for breast, colon and pancreatic cancers. A 2023 review revealed this links to insulin spikes: high blood sugar levels spur growth-friendly environments. Dr. Fung underscores the connection: “Insulin’s role as a growth factor means even non-diabetic patients with elevated levels gain cancer risk.” For women, this means a 30% higher likelihood of breast cancer per 5 BMI units above healthy ranges. Obesity’s collateral damage extends to the immune system. Chronic inflammation, driven by fat cells, weakens immune surveillance—the body’s cancer-detection mechanism. This explains why transplant patients on immunosuppressants face cancer surges: without a healthy immune system, dormant cancers reawaken.

Immunotherapy: The body’s built-in healing

While radiation and chemo remain staples, immunotherapy is redefining treatment. Therapies like CAR-T cell therapy reprogram patients’ white blood cells to target tumors, avoiding the collateral damage of traditional methods. “The goal is to restore balance, not just kill cells,” Fung explains. This approach aligns with functional medicine’s principles, supported by alternative practitioners like Dr. Ben Johnson, who condemns mammograms for overexposing breasts to radiation. His book No Mammograms! advocates thermography and ultrasound—a 95% sensitive imaging tool—as safer alternatives. Despite skepticism from mainstream medicine, thermography’s thermal mapping has detected cancers missed by mammograms. “FLIR cameras, even smartphone-attached ones, now reveal inflammation in real time,” says Dr. Migalka, citing cases where thermal imaging guided dietary interventions to combat tumors.

Retroviruses and the immune paradox: A hidden culprit?

Paralleling Fung’s focus on immunity is emerging insight into retroviruses—ancient viral DNA占15% of the human genome. Though “defanged” by evolution, these retroelements may resurface in immune-compromised states, driving autoimmune disorders and cancer. Dr. John Coffin’s work identifies retroviral ties to leukemia and ALS, while Dr. Migalka links them to conditions like chronic fatigue syndrome—a theory darkly echoing 20th-century outbreaks traced to vaccines. “Inflammation is the common thread,” says Dr. Marko Mijat, co-presenter of a 2023 retrovirus review. “Diet, stress and toxins disrupt systems balanced by our ancestors.”

Practical steps: The cancer-fighting lifestyle

The message is clear: prevention is a daily choice. Experts recommend:
  • Diet First: Plant-based meals rich in antioxidants (berries, cruciferous greens) stabilize insulin and quell inflammation.
  • Move Regularly: 30 minutes of daily exercise boosts immunity and detoxifies systems.
  • Screen Smart: Combine thermography with ultrasound for noninvasive early detection.
  • Stress Less: Meditation and sleep repair DNA, per studies on cortisol’s immune-crippling effects.

A new era of proactive health

As science dismantles the “incurable” myth, individuals hold unprecedented power. Whether through lifestyle shifts, cutting-edge immunotherapy, or noninvasive screening, the tools exist to reduce one’s cancer odds profoundly. Dr. Migalka’s thermography advocacy and Dr. Fung’s cellular “soil” metaphor coalesce into a unified call: Health is not a byproduct of genes or medicine alone. It’s built daily—one bite, one breath, one choice at a time. Sources for this article include: TheEpochTimes.com ACSjournals.wiley.com CancerResearch.org
