Natural Oncology, A Biological Terrain Approach to Cancer
Explore a new perspective on cancer with Mark Sircus’s latest book on Natural Oncology. This groundbreaking work examines how inflammation, toxicity, metabolic dysfunction, and environmental stress create the conditions for cancer — and presents a non-toxic, terrain-based approach focused on restoring the body’s natural balance through nutritional medicine, oxygen therapies, and metabolic support. More than a book, it also connects readers to comprehensive online cancer courses offering practical guidance for prevention, healing, and supportive care. Read More

Natural Cardiology
Nothing is more important to understand and know than how to prevent and recover from cardiovascular disease (CVD). It is as big a subject as curing cancer and age-related neurological decline. Natural Cardiology is a revolution in cardiovascular care, radically reformulating how heart and vascular patients must be treated. There is no getting away from the fact that mainstream cardiology relegates their heart patients to a slow but eventual death. It’s the same with diabetic care. The best conventional medicine can do is delay these diseases’ progression. Read More
Natural Endocrinology Book

As the world spirals out of control along many fronts, populations around the world, but especially in America, face a pandemic of suffering that no virus can compete with. We are specifically talking about diabetes, prediabetes, metabolic syndrome, kidney disease, and enough obecity to make one wonder how people survive it all.
The truth is that the suffering is off the Richter Scale, the amount of amputations is stupendous, and the pharmaceutical terror machine has doctors doing exactly the wrong things to help people. And how this all relates to heart and vascular disease, and even câncer, speaks volumes about a collapse in modern medicine prescribing exactly the wrong drugs for all of these conditions.

Welcome To A Revolution In Cardiology
I am proud to announce the launch of my new website, Natural Cardiology — where I’ve poured decades of clinical insight, personal battles, and relentless research into a groundbreaking approach to heart and vascular health. This isn’t just another health site; it’s a manifesto for a new medicine — one that frees us from the toxic grip of statins, beta‑blockers, and the endless parade of pharmaceutical poisons dished out by mainstream cardiologists.

What are the 21 Basic Causes and 4 Basic Characteristics of Cancers?

We don’t actually have a model to describe cancer that embraces the entirety of it. Modern oncology has ‘the world is flat’ type of model that is blinding and incredibly limited. Conquering Cancer breaks down cancer into basic causes and characteristics. It gives for the first time a road map of the territory we need to think about and then travel across when it comes to treating câncer. It puts knowledge in our hands and information in our brains so that our struggle against cancer is intelligent. Read More

Hydrogen Medicine

Hydrogen Medicine Book Cover

Treating cancer with hydrogen, oxygen and carbon dioxide is an approach that treats the fundamental reasons cancer cells form and get aggressive. The sicker a person is the more they will experience the benefits of hydrogen. Hydrogen can be flooded into the body to put out the worst flames of inflammation and oxidative stress. The longer one wants to live the more one supplements with these primary gases. The most powerful healing/medical/anti-aging device in the world is a hydrogen oxygen inhaler.

Hydrogen At the Center of Modern Medicine
When I was writing Forbidden Cures in 2022, I realized that my work had evolved into a system of medicine that is led and centered around the use of a most incredible medical gas. Hydrogen Medicine is revolutionary, and it holds the potential to save lives, reduce suffering and make one beautiful and young again through its anti-aging effects. Read More

There is a lot for us to learn about the causes of cancer but the most basic cause, the one that the other fundamental causes cause, is low oxygen delivery to the cells. “Low oxygen levels in cells is the primary cause of uncontrollable tumor growth in most cancers,” according to Dr. Ying Xu at the University of Georgia.


Mainstream cancer treatments are a disaster. A lot more cancer patients are going to die because of shortages of chemo agents, because of a scarcity of doctors in England, because of turbo cancers caused by genetic vaccines which oncologists refuse to recognize, and because doctors and the medical and health officials that stand behind them refuse to acknowledge safe alternative treatments that patients can do at home. The situation is terrible and getting worse.

Natural Oncology Site
Natural Oncology, led by Dr. Mark Sircus, treats the terrain, not just the tumor. Cancer reflects deeper imbalances — toxins, poor nutrition, low cellular energy — and restoring that internal environment restores the body's capacity to heal. The approach combines natural chemotherapy agents, hydrogen inhalation therapy, carbon dioxide therapy to flood tissues with oxygen, chlorine dioxide protocols, and essential minerals like magnesium and iodine. Cancer thrives on hypoxia and inflammation; reversing that oxygen deficit is central. Personalized consultations bring these natural allopathic protocols together into truly integrative care — creating an environment where cancer cannot thrive and long-term health becomes possible again.

Magnesium for life
Magnesium is as mission-critical as your next breath; without it, the body simply cannot function at its best. It is not a "nice to have" luxury but an absolute necessity, representing the core piece of the medical health puzzle that characterizes modern medicine and the epidemic of chronic diseases. We are currently facing a genuine health emergency: a silent epidemic of magnesium deficiency affecting most chronically ill individuals. Whether it is cancer, diabetes, or heart disease, potentially 90% or more of these patients are running on empty regarding this essential element. Read More

I'm Mark Sircus, a doctor of natural medicine and writer of more than 23 books that have sold 80,000 copies around the world. Natural Allopathic Medicine is the name of a new form of medicine I have pioneered that situates itself between the best of medical science and natural medicine.

A New Way To Think and Practice Medicine
Modern medicine is a death trap — a system designed to manage symptoms with pharmaceutical poisons, not to heal. Dr. Mark Sircus dismantles this failed paradigm by revealing what doctors were never taught: the body is a self-regulating intelligence built on chemistry, electricity, minerals, gases, and consciousness. At the core lies the carbon dioxide revelation — CO₂ isn't waste; it's the gas that delivers oxygen to your cells. Its systematic depletion drives most chronic disease. This book delivers practical tools: magnesium, sodium bicarbonate, iodine, pH balance, mitochondrial repair, and terrain-based immunity. It's for anyone ready to reclaim their health from a system that profits from sickness. The truth does not require permission. Read More
Discover a new approach to medicine based on CO₂, oxygen delivery, minerals, mitochondrial health, pH balance, and the body's biological terrain.

Consultations With Dr. Sircus

For over twenty years, I have been doing online consultations. People reach out to me for all kinds of reasons. Though in medicine we concentrate on the body often it is important to consider emotional and mental dimensions, which I do. Though my system of medicine is simple it is helpful to have a guide if its vital you get it done right. This holds especially for cancer patients. Besides consultations I have an online clinic to offer continuing individual support.
