The Chiropractic Connection to Immunity
The Chiropractic Connection to Immunity: A Natural Path to Cancer Prevention
By Dr. Billy DeMoss
Introduction
Chronic disease is more common now than at any point I have practised, and cancer rates continue to climb. Most of the conversation around that is about treatment — chemotherapy, radiation, pharmaceuticals — and far less of it is about what happens before any of that is needed. After forty years in practice I have come to think prevention deserves more of our attention than it gets.
The body is built to repair itself. That is not a slogan; it is what physiology describes. Modern life interferes with that capacity in a dozen ways — sustained stress, poor sleep, sedentary work, inadequate nutrition, environmental exposures. My view, and it is a view rather than a settled finding, is that supporting the systems that govern repair is worth doing, and that spinal health is one legitimate part of that picture.
The nervous system and the immune system are connected
This part is not in dispute. The nervous and immune systems communicate constantly and in both directions. Immune organs carry nerve supply. Immune cells respond to the chemical messengers the nervous system releases. The autonomic nervous system regulates circulation, inflammatory signalling and the release of cortisol and adrenaline, all of which shape how immune cells behave.
What follows from that is a reasonable question rather than a proven answer: if the nervous system influences immune function, does the condition of the spine that houses and protects it matter? I believe it does. The research has not settled it, and anyone telling you it has is overstating the case.
Chiropractic adjustments and immune function
A number of studies have looked at markers of immune activity following spinal adjustment. Some report changes; others do not. The studies are mostly small and the clinical meaning of what they measure is not established. I am not going to represent that literature as stronger than it is, because you can read it yourself and because a claim that will not survive scrutiny helps nobody.
What I can say from four decades of watching patients is narrower and, to my mind, more useful. People who are out of pain sleep better. People who sleep better are more resilient to the things that come at them. People who can move without hurting stay active, and activity has a genuine and well-documented relationship with immune function. That chain is real even if the direct mechanism is unproven.
Chronic inflammation and restricted spinal segments
Low-grade chronic inflammation is one of the more consistent findings across a range of long-term diseases. It is influenced by sleep, activity, body composition, smoking, alcohol and stress — and persistent musculoskeletal pain touches most of those.
A spinal segment that has stopped moving properly irritates the tissue around it and keeps the surrounding muscle guarding. That is a local inflammatory picture and restoring the movement settles it. Whether resolving that has a measurable systemic effect is a bigger claim, and one I would want better evidence for before making it to a patient.
Detoxification, and what the word should mean
Your liver and kidneys handle detoxification and they do it well. No adjustment improves on that, and I want to be blunt because the word gets used loosely in this field. What movement genuinely does is support circulation and lymphatic flow — the lymphatic system has no pump of its own and depends on muscular activity to move fluid. Someone in too much pain to move is doing less of that than they should. Getting them moving again is the contribution, and it is a modest and honest one.
Stress, and why I keep returning to it
Prolonged stress alters immune function measurably. That is well established, and it is one of the clearest routes by which how you live affects how well your body defends itself. Patients regularly describe feeling calmer after treatment, and I take that seriously — while acknowledging that massage, exercise and an unhurried conversation with someone who listens all produce something similar. I would not attribute it solely to spinal alignment.
A prevention-focused life, of which this is one part
If you want to reduce your risk of serious disease, the evidence points clearly at a handful of things: do not smoke, stay physically active, keep a healthy weight, limit alcohol, protect your skin, eat a diet built on whole foods, sleep properly, and manage stress. Vaccination against HPV and hepatitis B prevents cancers directly. Attending screening when you are invited catches disease early enough to treat.
That is the foundation, and none of it involves me. Where I think chiropractic care fits is alongside it — keeping people moving well enough and comfortable enough to actually do those things, year after year. A patient who cannot walk without pain will not exercise, and telling them to is not a plan.
What I would say to a patient
That chiropractic care is not a cancer treatment and I would never present it as one. That I believe supporting the nervous system is a sensible part of a prevention-focused life, and that this is my clinical view rather than something the research has settled. And that if you are due a mammogram, a colonoscopy, a cervical screening or a skin check, go — because nothing on this page substitutes for that, and early detection saves more lives than anything else in this conversation.
If you have noticed a lump, unexplained weight loss, a change in bowel habit, a mole that has changed, or bleeding you cannot account for, see your physician promptly. Please do not wait, and please do not treat a chiropractic visit as the appropriate first step for any of those.
Empowering the body's natural defenses
The Chiropractic Connection to Immunity, as I understand it after forty years, is not a dramatic claim. It is that the body has a considerable capacity to look after itself, that this capacity is affected by how we live, and that being out of pain and able to move is a real part of living well.
That is worth something, and it is worth stating carefully. I would rather patients trusted what we say here because it holds up than because it sounded impressive.
