What if cancer isn't just a genetic disease—but a deep metabolic misfire, a sign that the cell’s most fundamental energy system has buckled under the weight of chronic stress?
A compelling new review by Seyfried et al. (2025) in the Journal of Bioenergetics and Biomembranes reopens a century-old question and offers a modern answer: cancer may arise not from rogue genes, but from a profound breakdown in mitochondrial energy metabolism. And this breakdown, the authors argue, is not random—it is the maladaptive endpoint of a sustained stress response.
Let’s explore this mitochondrial view of cancer—and what it reveals about stress, energy, and resilience.
🔬 The Mitochondrial Metabolic Theory of Cancer
First proposed by Otto Warburg in the 1920s, the idea that cancer cells rely on fermentation instead of oxidative metabolism has long sparked debate. Warburg believed that the root of cancer was defective mitochondrial respiration, even in the presence of oxygen—a phenomenon now commonly called the “Warburg effect.”
But today, thanks to advances in systems biology and cancer metabolism, we can dig deeper.
According to Seyfried and colleagues, cancer is marked by:
Insufficient ATP production from oxidative phosphorylation (OxPhos),
Compensatory overactivation of substrate-level phosphorylation (SLP), and
Chronic accumulation of metabolic waste products like lactate and succinate, even in the presence of oxygen.
This isn’t just a quirk of cancer. It’s a classic pattern of maladaptation to unresolved stress.
⚙️ SLP vs OxPhos: The Energetic Trade-Off
Under normal conditions, healthy cells generate most of their ATP via OxPhos, a highly efficient process in the mitochondria that requires oxygen. But when mitochondria are damaged or overwhelmed—say, by inflammation, hypoxia, or oxidative stress—the cell shifts to a backup strategy: substrate-level phosphorylation (SLP).
Unlike OxPhos, SLP can generate ATP without oxygen. It’s quick, dirty, and ancient. It occurs:
In the cytosol via glycolysis (glucose → lactate), and
In the mitochondria via glutaminolysis (glutamine → succinate).
In the short term, this switch helps the cell survive. But when the stress persists, and OxPhos remains impaired, SLP becomes the dominant mode of ATP production. Over time, this leads to:
Redox imbalance
Impaired repair and regeneration
A pro-inflammatory, pro-growth metabolic state
And ultimately: dysregulated cell growth—aka cancer.
🔁 Cancer as a Failure of Energy Recovery
From a systems resilience perspective, this is striking. Cancer may not start with mutations, but with unresolved mitochondrial distress:
Stress hits — infections, toxins, hypoxia, inflammation.
Mitochondria falter — OxPhos drops, ROS rise.
SLP takes over — a compensatory survival mechanism.
Genomic instability emerges — fueled by ROS and bioenergetic chaos.
Mutations accumulate — not as causes, but as consequences.
In other words, cancer could be a bioenergetic survival mode that never resolved—a failed recovery, not a programmed rebellion.
🧭 The New Therapeutic Frontier
If cancer is rooted in mitochondrial maladaptation, this changes everything about how we treat and prevent it.
Seyfried and colleagues propose a “Press-Pulse” strategy:
Restrict glucose and glutamine, the main fuels for SLP,
Elevate ketones, which support healthy OxPhos and reduce oxidative stress,
And target metabolic flexibility—not just genetic mutations.
This aligns with growing evidence that metabolic therapies, such as ketogenic diets or targeted fasting, may help starve cancer cells while nourishing healthy ones.
🌱 Final Thoughts: What Cancer Teaches Us About Chronic Stress
This new research doesn’t just offer a fresh take on cancer—it underscores a core truth about chronic disease:
Stress adaptation has a cost. And when the stress never ends, the cost may be cancer.
Mitochondria are our earliest sensors of survival strain. When their capacity to produce energy falters, cells turn to primitive pathways to keep going. But if we never resolve the energy crisis—if the mitochondria never recover—the adaptations become the disease.
And that’s not just a theory. It’s the metabolic footprint of modern illness.
