Can you prevent cancer? This is a question I hear almost daily, especially from people with a family history of cancer, those who have lived what they consider a healthy lifestyle, or anyone who has watched someone close to them struggle with a diagnosis and wants to lower their own risk.
I break down three foundational areas that matter when the goal is reducing cancer risk and supporting the body’s ability to regulate abnormal cell growth.
We first have to start with stress and cortisol, and how chronic elevation can interfere with tumor-suppressor pathways like P53, the gene responsible for monitoring and repairing cellular damage. We also talk about daily chemical exposure and why detox support is important even when you do everything “right.”
Vitamin D is another key piece.
Many people assume sun exposure is enough, yet low levels are extremely common, especially in those with active cancer. Genetics can influence how well vitamin D is activated, which is why testing matters more than guessing.
The third area is metabolic health.
Carbohydrate load, insulin signaling, and frequent insulin spikes can influence inflammation and growth signals in the body. Timed eating and calorie restriction are discussed as tools that, when used appropriately, support better metabolic regulation.
When fasting is addressed through a personalized lens, including how lab work, hormone cycles, stress response, and overall metabolic health should guide decisions. Longer fasts are not always beneficial and can increase stress or destabilize blood sugar if not matched to the individual.
Fasting and metabolic strategies can be powerful tools, but they are only effective when they support the body rather than add stress. Lab markers, such as fasting insulin, hemoglobin A1C, inflammatory markers, vitamin D status, and genetic factors, provide critical context.
The goal is not to follow extreme protocols, but to understand what your body is signaling and create a plan that supports immune regulation, hormone balance, and long-term resilience.
