Oh, Shit, I Have Cancer. Now, What Do I Do?

Published on April 17, 2025

A Thousand Choices. And Not One Clear Answer.

A doctor points to the phrase 'Stop Cance' displayed prominently on a poster.

The multitude of treatment avenues—from established therapies to experimental and alternative methods—can be daunting. There are too many cancer treatments, from the mainstream to the obscure to the experimental, and this overabundance—this flood of options—can drive patients into paralysis, confusion, and desperation.

If you’re a patient—or a parent—facing cancer, you have the opinions of your first chosen doctor, and then online, you are given so many choices, each one sold with conviction, urgency, and a trail of anecdotal or clinical support—that it doesn’t feel like freedom anymore. It doesn’t feel kind. Because no patient facing cancer wants to become an expert in oncology, but if they’re going to survive, they must.

I was motivated to write this essay after reading about a new cancer therapy that has been promoted as the best yet; however, it is hard to find. And to top it off, it was being promoted by an anonymous doctor called the Midwestern doctor, who said, “When DMSO is combined with hematoxylin (a dye widely used in pathology), it becomes a highly potent cancer treatment, both harnessing DMSO’s intrinsic anticancer properties and directly destroying cancer cells.

One more treatment added to a long, long list of possibilities that cancer patients must face. A cancer diagnosis used to come with one or two options. Today, it comes with a hundred. Depending on who you ask, you might be told to burn it, poison it, starve it, flood it with oxygen, extract it surgically, suppress it with hormones, reprogram it with mRNA, or align your chakras and drink carrot juice.

Each one of these has survivors who swear it saved their lives. Each one has critics who call it a scam. Most exist without precise long-term data. Some are illegal in one country, and some are standard protocols in another.

Also, Ivermectin, an anti-parasitic drug that’s been around for decades, originally used to treat lice, scabies, and river blindness, is now being promoted by figures like Dr. Pierre Kory, Dr. Paul Marik, and The FLCCC Alliance. Initially, for COVID-19 now it is being suggested as a potential anticancer agent by various integrative and alternative medicine advocates. They often cite studies suggesting that Ivermectin may inhibit tumor growth, block cancer cell replication, enhance immune system function, and interfere with specific signaling pathways cancer cells use.

Fenbendazole, a veterinary dewormer, is also widely discussed in these same alternative circles as a potential cancer treatment. And don’t forget about Mebendazole. Like Fenbendazole, Mebendazole is a benzimidazole-class anti-parasitic used in humans, commonly to treat pinworms and other intestinal parasites. It’s been around forever. But recently, it’s been repurposed and promoted as a low-toxicity anticancer agent. So, you often see these three in the same sentence or protocol.

The treatment landscape is no longer a crossroads. It’s a labyrinth.

When every path is possible, and none are guarantees, what you give the patient is a burden. The burden of research, comparison, and choice. The burden to get it right. The very process of deciding becomes a source of trauma. And this, on top of cancer.

The system doesn’t just ask you to fight cancer. It asks you to fight the fog of options.
To fight the guilt if you choose wrong. To fight the doubt in the middle of chemo or the panic of rejecting it.

The world of patients is currently divided into two camps. Some do not doubt their doctors and their government and embrace CT scans, biopsies, chemo, and radiation therapy, though, of course, they are scared to death, as they should be, of these very aggressive, toxic treatments that cause a host of severe side effects including death. And then others do not trust the mainstream of medicine and seek out alternative, more natural ways of dealing with their cancer.

There will be a lot of pressure from our doctors to do things their way, and God forbid it is your child who has cancer. One might be threatened by child protective services that will take your child from you if you do not comply with everything the oncologist wants to do. And then there are family and friends who want to decide for us.

Over the oxygen supply of the body carbon
dioxide spreads its protecting wings.
Friedrich Miescher
Swiss physiologist, 1885

I have written hundreds of articles on cancer, have a 112-lesson course, and an Emergency Treatment Course that is designed to quickly get a patient up and running on a basic treatment protocol. I concentrate on the basic treatments that the body needs in an absolute sense and build a protocol from there. Then come all choices, but it is not a matter of choice for some things. Breathing, for instance, is the most basic and immediate thing; in cancer treatment, it is vital to learn to breathe slowly.

Carbon Dioxide Therapy

Blood test results show normal levels, as confirmed by an 85-year-old man's testimony.

Carbon Dioxide Inhalation has a long history. An 85-year-old former lawyer shared a powerful story. After learning to shift his breathing from “jerky and gaspy” to slow and calm, he no longer needs blood transfusions after many years of dependency. “I feel stronger, more alive—and I’ve regained my health and appetite for life.” Don’t you think this would help cancer patients fight their cancer? Yet how many doctors even consider this something important to pay attention to?

Understanding cancer is essential because it helps you decide which therapies to choose more intelligently. To not understand how acid and low oxygen conditions influence cancer is not to understand cancer. Over 80 years ago, Warburg showed that cells could always be made cancerous by subjecting them to periods of hypoxia. Cancer cells survive by utilizing a process that is advantageous in low-oxygen environments.

Cancer’s Secret That Most Ignore

D F Treacher and R M Leach teach, “Oxygen transport from environmental air to the mitochondria of individual cells occurs as a series of steps. The system must be energy efficient (avoiding unnecessary cardiorespiratory work), allowing efficient oxygen transport across the extravascular tissue matrix. At the tissue level, cells must extract oxygen from the extracellular environment and use it efficiently in cellular metabolic processes.”

Acidity depresses oxidation, and increasing alkalinity, even to a marked degree, dramatically increases the oxidation rate. This means that when acid conditions prevail, the oxidative process inside the mitochondria is severely compromised, and it’s no surprise that oxidation is remarkedly facilitated as we switch to alkaline conditions.

According to Warburg, damaged cell respiration causes fermentation, resulting in low pH (acidity) at the cellular level. “In every case, during the cancer development, the oxygen respiration always falls, fermentation appears, and the highly differentiated cells are transformed into fermenting anaerobes, which have lost all their body functions and retain only the now useless property of growth and replication. Thus, when respiration disappears, life does not disappear, but the meaning of life disappears, and what remains are growing machines that destroy the body in which they grow.”

The Warburg cancer theory postulates that the tumorigenesis driver is insufficient cellular respiration caused by an insult to mitochondria. In other words, instead of fully respiring in the presence of adequate oxygen, cancer cells ferment. Cancer is a metabolic disease, a fermentation caused by malfunctioning mitochondria, resulting in increased anabolism and decreased catabolism.

Hypoxia or anoxia results in a dramatic decrease in adenosine triphosphate (ATP) levels. Hypoxia is the stimulus that creates the need for a replacement for the lost ATP. If the cell wants to survive (not suffer cell death), it must turn to fermentation, and it does. When oxygen becomes limited, mitochondrial oxidative phosphorylation (OxPhos) is restricted, and pyruvate is converted to lactate.

Dr. Rockwell from Yale University School of Medicine (USA) studied malignant changes on the cellular level and wrote, “The physiological effects of hypoxia and the associated microenvironmental inadequacies increase mutation rates, select for cells deficient in normal pathways of programmed cell death, and contribute to the development of an increasingly invasive, metastatic phenotype. “In response to hypoxia, mitochondria generate an initial burst of ROS.

Dr. Robert Rowan says, “Warburg emphasized that you can’t make a cell ferment unless a LACK OF OXYGEN is involved. In 1955, two American scientists, R.A. Malmgren, and C.C. Flanigan, confirmed Warburg’s findings. They found that oxygen deficiency is ALWAYS present when cancer develops. Warburg found that you can reverse fermentation simply by adding oxygen – but only if you do it early enough. He incubated cells in nitrogen, starving them of oxygen for regular but short periods. Starving the cells of oxygen caused them to begin fermentation. Restoring oxygen promptly enabled the cells to recover. But the longer they were oxygen-starved, the slower and less certain the recovery. With enough oxygen starvation, cells don’t recover. Once they reach a certain point, no oxygen will return them to normal.”
