When It Comes to Cancer, Most Doctors Don’t Know What They Are Talking About

Published on October 24, 2025

Another title for this essay could have been: “Vitamin D is Crucial for Cancer Treatment and Everything Else.” This is an example of why my medical religion is protocol, which means never championing a single substance for cancer treatment or anything else. It is why my hair bristles when I hear so many doctors these days screaming about Ivermectin or Fenbendazole. Or maybe a good title would be “Natural Medicine is Real Medicine,” because it addresses the body’s real needs.

Doctors can be the most ignorant people on Earth, or they wear blinders like thoroughbred racehorses coming out of the gates. Many substances can help cancer patients, and good doctors will be talking about many of them at the same time to be effective at treating Cancer with compassion and care.

Oncologist Prof. Angus Dalgleish revealed a game-changing finding to pancreatic cancer expert Daniel Von Hoff: his successful immunotherapy trial insisted on normal Vitamin D levels. Skeptical, Von Hoff reviewed 30 years of data from 4,000 patients. The result was staggering as not one patient with low Vitamin D had responded to chemotherapy.

The “responders” in his past trials were simply those with adequate Vitamin D levels. The drug alone wasn’t the hero; it needed a competent immune system, primed by Vitamin D. The takeaway: Vitamin D is non-negotiable for immune function. Every white blood cell has receptors for it. The official “normal” level (~50 nmol/L) is too low. For therapy, aim for >100 nmol/L. Correcting this deficiency could be the key to turning non-responders into responders. A simple, safe, and foundational step we can no longer ignore.

One of the reasons modern medicine and specifically modern oncology is so crippled is its aversion to natural medicine, which is not alternative medicine at all. It is essential medicine. Essential and crucial because it addresses the body’s real needs. Vitamin D is just one example. So, doctors are trained to be stupid, and JFK Jr’s insistence that they start teaching nutrition in medical school is only a tiny, bitty step in the right direction. All one must do is look at what modern hospital nutrition dishes out to see what will be taught.

Imagine trying to treat Cancer with chemotherapy in a severely deficient magnesium patient. How far do you think that will go? Or a severe iodine and selenium deficiency? Or on a person who is breathing too fast, driving down both their carbon dioxide levels in the blood and thus their oxygen levels. These are all basic things that doctors commonly overlook completely. Sure, they have their excuses, a long list of them as their patients die in droves.

Oxygen: The Most Basic Natural Medicine

How many oncologists understand and work with oxygen? Dr. Arthur C. Guyton says, “All chronic pain, suffering, and diseases are caused by a lack of oxygen at the cell level.” Insufficient oxygen means insufficient biological energy, resulting in anything from mild fatigue to life-threatening disease. “Oxygen plays a pivotal role in the proper functioning of the immune system,” said Dr. Parris M. Kidd. Low oxygen levels directly lead to inflammation. Chronic inflammation mirrors our body’s low oxygen state.

Anything that threatens the oxygen-carrying capacity of the human body will promote inflammation and cancer growth. Hypoxia (low oxygen) is a potent activator of inflammation, and inflammation is the most common cause of tissue hypoxia and decreased circulation. Inflammation and hypoxia feed on each other.

Hypoxia and inflammation characterize Cancer. All types of inflammation can cause Cancer, and inflammatory responses play decisive roles at different stages of tumor development, including initiation, promotion, malignant conversion, invasion, and metastasis. Low levels of oxygen typically characterize inflamed and injured tissues.

In all severe disease states, we find a concomitant low oxygen state.
Low oxygen in the body tissues is a sure indicator of disease.
Hypoxia, or lack of oxygen in the tissues, is the
fundamental cause for all degenerative diseases.
Dr. Stephen Levine – Molecular Biologist

Oxygen pulls the rug out from under cancer cells and tumors by removing the basic condition that makes them virulent. Bicarbonates do the same thing, so using oxygen and bicarbonate together is lethal to cancer cells. Low Oxygen Causes Infections, which Cause Cancer, & The Key Cause of Cancer is Oxygen Deficiency.

How Many Oncologists Understand the Importance of pH in Cancer?

How cancer cells move and metastasize is influenced by the fluids surrounding them. In recently published research, medical scientists from Binghamton University found that human breast cancer cell migration is enhanced by the flow and viscosity of the fluids surrounding them, clarifying one of the factors influencing tumor metastasis. The influence of pH on viscosity is a complex and multifaceted phenomenon that is important to understand to achieve successful cancer treatment outcomes.

One key feature of cancer cells, including breast cancer cells, is a reversed pH gradient, which makes the extracellular pH of cancer cells more acidic than that of normal cells. A growing body of literature suggests alkaline therapy could reverse the pH gradient back to normal and treat Cancer.

“Cancer cells inside the body live in a complex environment or neighborhood. Where the tumor cell resides and who its neighbors are influence its response and resistance to therapy,” said senior author Dr. Peter S. Nelson, a member of the Hutchinson Cancer Center‘s Human Biology Division. “Our findings indicate that the tumor microenvironment also can influence the success or failure of these more precise therapies.” In other words, the same cancer cell, when exposed to different “neighborhoods,” may have very different responses to treatment.

Can You Find One Oncologist in the USA who knows about Hydrogen Medicine?

Hydrogen Cancer Control book cover

In the book “Hydrogen Cancer Control – Theory and Practice” by Professor Xu Kecheng, a well-known Chinese gastroenterologist and tumor treatment expert, it was found from 82 actual surveys of late-stage cancer patients that inhaling a mixture of Hydrogen and oxygen has a positive effect on cancer pain and sleep apnea. Symptoms such as disorders and loss of appetite are improved, the patient’s quality of life is enhanced to a certain extent, the side effects of chemotherapy are reduced, and it plays an auxiliary role in the decline of tumor markers and in inhibiting tumor growth.

Hydrogen inhalation is a simple, low-cost treatment with few adverse reactions that warrants use as a strategy for the clinical rehabilitation of patients with advanced Cancer. Molecular Hydrogen (H2) induces anti-proliferative, anti-oxidative, pro-apoptotic, and anti-tumoral effects. In a systematic review of molecular hydrogen therapy for cancer management, researchers found consistent evidence that hydrogen inhalation has a promising therapeutic role as an independent therapy and as an adjuvant in combination therapy, resulting in overall improvements in survival, quality of life, blood parameters, and tumor reduction. The best, most powerful, and easy-to-use hydrogen/oxygen inhalation machine is available here.

How Many Oncologists Use Bicarbonates as a Basic Form of Chemo? None!

There are four easy-to-understand actions of bicarbonates. First, according to the latest research from the Ludwig Cancer Institute, bicarbonate floods into cancer cells, forcing them to turn back on the circadian rhythm that they shut off so they can eat around the clock, be as aggressive as possible, and spread. The clock for normal cells governs the timing of rest, regeneration, and recuperation, and 12 hours for activity and eating. So, bicarbonates, though they might not kill cancer cells outright, put them at a disadvantage because they cannot eat as much. That would make them less virulent and more vulnerable.

The second major thing bicarbonate does is neutralize the lactic acid surrounding cancer tumors. Acidic fluids and tissues incapacitate killer T cells, making them lazy and ineffective. But when the acid surrounding tumors is neutralized, it calls up the Marines of the immune system, which are these killer T-Cells, and they will be able to penetrate and kill, as good Marines do, the enemy.

A type of T cell called a cytotoxic T cell can recognize the mutated proteins in cancer cells and should, therefore, be able to kill them. However, in most patients, cancer cells grow unchecked despite T cells, as T cells are inactivated in hypoxic, acidic areas surrounding most cancer cells and tumors. Go after these pockets and take them out with bicarbonates, carbon dioxide, and oxygen, and you take a significant step toward winning the war on Cancer.

The third significant effect of bicarbonates is to flood the body fluids with oxygen (by increasing CO2 levels), which lifts all boats and strengthens the immune system. The more acid the body has —i.e., the more H+ ions —it has, the less oxygen it has, whereas alkalinity is OH, meaning the more alkalinity there is, the more oxygen there is.

How cancer cells move and metastasize is influenced by the fluids surrounding them. The fourth significant effect of increased bicarbonate (CO2) in the body is its influence on the extracellular environment around cancer cells and tumors. Everyone knows that all biological life is pH-sensitive, which applies to both the inside and the outside of cancer cells. The cells’ surroundings, known as their microenvironment, contribute to how Cancer occurs and spreads.

The interactions between cancer cells and their micro and macro environments create a context that promotes tumor growth and protects them from immune attack (cutting the immune system’s Marines’ legs, the second significant effect). Cancer cells cannot turn into lethal tumors without the cooperation of nearby cells. It is not just the surrounding cells but also the interstitial environment, which is mainly controlled by pH. Bicarbonate offers radical shifts in pH.

Simple! It is too simple for oncologists, who make a lot of money dispensing toxic chemotherapy, and too cheap for pharmaceutical companies. Bicarbonate also addresses the basic deficiency of bicarbonate in the bloodstream, which is the same as saying low carbon dioxide in the blood, which forces down oxygen delivery to the cells.

Carbon dioxide is a nutrient as well as a product of respiration
and energy production in the cells, and its lack or deficiency
is of itself a starting point for different disturbances in the body.

There are numerous ways to increase bicarbonates and CO2 in the blood. First, there are sodium, potassium, and magnesium bicarbonates. One can use these orally, with sodium bicarbonate, which can also be nebulized and used in full-foot baths at high concentrations. Magnesium bicarbonate produces the best-tasting drinking water. Then, one can use CO2 directly with a CO2 inhaler, which will become available in February 2024.

This is a must-book for any home or office medical library.

Most people assume correctly that chemotherapy is incredibly toxic with side effects that can rip your heart apart, provoke more Cancer, and cause misery and an earlier visit to a grave. No one disputes the long list of nasty side effects of chemotherapy. Chemo is poisonous, and sometimes, it does poison cancer cells before it poisons and kills the patient.

I could go on all day, and I do have the most extensive cancer course available anywhere in the world, one hundred and twelve lessons, and a multi-media emergency cancer treatment course that substitutes for a series of consultations with me.

This essay is about what used to be standard cancer, the kind that has been a nightmare of suffering, pain, and death for people around the world. Now it’s different; we have a tidal wave of vaccine mRNA-driven Turbo-Cancer, and if you ever thought standard Cancer care was a nightmare, now it’s worse. much worse. And it’s all being covered up by the government and the press. So, if you think the title was a little over the top about doctors, specifically oncologists, not knowing what they are talking about when it comes to cancer, they are totally blind to vaccine damage-driven cancer.
