New Free Book on Repurposed Drugs and Metabolic Interventions for Cancer by Highly-Published Critical Care Specialist Paul Marik

It's hard to overstate how exciting this book is! We now have a well-respected doctor using quality research to verify that alternative cancer treatments are evidence-based and highly effective!

Jan 16, 2024

Paul Marik just released a new book available for free download called Cancer Care: The Role of Repurposed Drugs and Metabolic Interventions in Treating Cancer. Also available on this page for free are webinar slides explaining book, a book summary, and links for purchasing either the paperback or Kindle editions.

Dr. Marik poured over more than 1200 peer-reviewed papers to bring us the highest-caliber research exploring all the non-conventional cancer treatment options available. This book represents the turning of the tide away from the conventional drug cartel that has controlled cancer care for far too long with horrific consequences.

Although there are numerous alternative cancer-cure books, this one is different because it’s written by an expert researcher with uncontested credibility.

Dr. Paul Marik is the most published critical care physician in the world. He has over 500 peer-reviewed journal articles that are cited over 43,000 times.

He first gained renown for discovering a sepsis protocol that reduced the ICU sepsis death rate from 40% to 8%. But his career as an ICU doc ended when he developed a similar protocol for COVID but was forbidden by his hospital from using it. (He tells the story in this moving clip from his testimony during Senator Ron Johnson’s “COVID: A 2nd Opinion” Senate hearing on January 24, 2022.)

The COVID debacle opened Dr. Marik’s eyes to the fact that big pharma is at war with repurposed drugs because they reduce its profits. This piqued his curiosity about how many cancer drugs could be repurposed.

So Dr. Marik got busy doing what he’d done for 30 years: researching. Now he had the time to do it in earnest, being out of a job.

His hospital not only suspended his practicing privileges for saving people’s lives without ventilators and Remdesivir (the hospital’s only approved protocols), they also made sure he could never practice medicine again. He says in this interview,

They reported me to the National Practitioner Data Bank. When you get reported to the National Practitioner Data Bank, your name is there forever, and it makes it almost impossible to get a license again in any state. The hospital essentially ended my career based on fraud, falsification of data, deceit, dishonesty, and unethical behavior.

But the beauty that has risen out of the ashes of that unprecedented circumstance is that the world now has a comprehensive new guide that summarizes the evidence for non-Chemo ways to treat cancer. (Note: I covered more of Dr. Marik’s story in this post.)

Cancer is First a Metabolic Disease

As exciting as it is to repurpose drugs for cancer, I’m also beyond thrilled that the book cites copious research showing that cancer is, first and foremost, a metabolic disease. Finally! Someone mainstream is saying this besides only the sidelined alternative voices!

But this amazing new development doesn’t come as a surprise to those who know Dr. Marik’s story. After waking up to the corruption in the medical system, his first big realization was that he had been fed a lie about his own type 2 diabetes being permanent and progressive. After treating it for 20 years with meds, he cured himself through intermittent fasting and reducing carbs, and came off his meds (as he explains in this nine-minute video).

Therefore, it makes sense that he would be looking for clues as to how insulin resistance could be behind other chronic diseases as well, such as cancer.

The summary of his book shows that his very first cancer intervention is using diet:

Here’s his rationale for cancer being a metabolic disease:

Since cancer cells thrive on glucose, keeping your blood glucose between 80-90 instead of 160-180 would supply the cancer with half the fuel. One can easily keep glucose that low through a combination of fasting and eating fewer ultra processed carbs.

Remember, fasting is not a fad diet to lose weight. It’s medical treatment.

How the book is researched:

Here are some slides from the book summary about how Dr. Marik sifted through the evidence to decide what cures to highlight.

Fenbendazole Update

Fenben made it onto Dr. Marik’s list of cancer protocols as #9!

The earliest readers of this Substack will remember a post I made almost a year ago now:

An Odd Cure for Incurable Cancer

February 21, 2023

I love finding crazy stories that no one would ever believe if they weren’t so well documented. Two weeks ago we covered Mikhaila Peterson who was dying of the most severe autoimmune disease her doctors had ever seen and how she cured herself on an all-meat diet and now lives a normal life. (

Read full story

This post covered the story of Joe Tippens who cured his metastatic lung cancer by taking fenbendazole. This was remarkable since the tumors had spread all over his body while on chemo and radiation. On Fenben, they all disappeared. This happened six years ago, and he’s had no recurrence of cancer.

Since I wrote that post a year ago, there’s been further confirmation as word of Fenben’s effectiveness has spread.

For instance, there is a Substack called Fenbendazole Can Cure Cancer devoted to documenting cases of people who have been cured of their cancer by using Fenben.

There is a Facebook group with 88,000 people called Fenbendazole - Cancer Support Group. (Note: you can only join if you have active cancer or are caring for someone with active cancer.)

And finally, Joe Rogan, who has one of the most listened-to podcasts in the world, averaging over 11 million people listening to each episode, recently talked about Fenben’s efficacy against cancer in this clip:

Even so, I was still floored to see Fenben listed as #9 on Dr. Marek’s well-researched protocol.

What seemed to some like pseudo-science last year has now been confirmed.

But keep in mind, Fenben was never truly pseudo-science.

The Internet abounds with anecdotal off-beat cancer cures, and there are numerous books on alternative protocols as well. However, the Fenben story stood out to me as different for a number of reasons:

1. Joe’s oncologist admitted that the class of drugs has known anti-cancer effects

Here’s how Joe tells the story on his website:

[My oncologist’s] next sentence almost floored me. He said, “You know, we’ve known for decades that these anthelmintic class of drugs (meaning to destroy parasites in the intestines) could have possible efficacy against cancer, and in fact in the 80’s and 90’s there was a drug called Levamisole that was used on colon cancer, and it is an anthelmintic drug.”
I said, “Doc, if you have known for decades why hasn’t more work been done on it?”
His answer was honest. He said, “Probably because of money…All of these drugs are far off-patent and nobody is going to spend a gazillion dollars to repurpose them for cancer only to have generic competition the next day.”

(Note: integrative cancer centers do repurpose drugs that are FDA-approved such as Ivermectin for off-label use. This practice is completely legal. In fact, 30% of drugs prescribed are off-label, meaning the physician prescribed the drug for a use other than what the FDA officially approved it for.)

2. The journal Nature explains how Fenben works

The journal Nature, one of the most prestigious science journals in the world, published an article in 2018 titled Fenbendazole acts as a moderate microtubule destabilizing agent and causes cancer cell death by modulating multiple cellular pathways.

The article outlines three main mechanisms by which Fenben destroys cancer. I’ll summarize them for you (you’re welcome):

FenBen destabilizes the cancer cell’s microtubules, which are key components in a cell’s cytoskeleton. When the microtubules are compromised, this inhibits cancer cell division, movement, and transportation of materials in and out of the cell.
FenBen interferes with the cancer cell’s uptake of glucose. Because cancer cells grow so rapidly, they need copious amounts of sugar. This is why fasting and a zero-carb diet can enhance other treatments.
FenBen induces apoptosis (programmed cell death) through the activation of a gene called P53. A healthy cell is programmed to divide only a specified amount of times and then die. This programmed cell death, called apoptosis, is turned off in cancer cells causing them to multiply indefinitely. FenBen reactivates apoptosis in cancer cells by activating the programmed-cell-death gene called P53.

People have cured their cancer by doing random things like juicing celery and fasting for 40 days. Likely the majority of these stories are true but none of them have an article explaining why they work in a highly-acclaimed, peer-reviewed journal like Nature.

I bring this up because it’s natural to be skeptical. We should be skeptical of claims. I don’t believe most of the health things I read on the Internet. But Fenben is decidedly different.

3. The Plural of Anecdote is Data

The Big Pharma shills have one play in this scenario and that is to screech about how there are no randomized clinical controlled trials proving Fenben’s efficacy. But the problem is that when a drug is off-patent, there is no motivation to fund the pricey research. Bringing a new drug to market can cost upwards of $2 billion.

However, the data continue to roll in on Fenben. Check out this website full of testimonials of people who’ve reversed their cancer. When enough anecdotes roll in, we have our data. The people who are unconvinced are the people who profit from the industry.

If you know someone with cancer, please consider sharing Dr. Marik’s free book with them. It may be just the info they need to consider an alternative treatment, especially if conventional treatment isn’t working or if the side effects become too dangerous.

(Side Note: I have a bone to pick with #12 of Marik’s protocol: take statins. Based on the research of over 100 medical and academic doctors who formed THINCS, an organization educating people about the harms of statins, no one should go on statins ever. But Marik has only recently escaped the entangles of the medical establishment so we can’t expect him to unlearn everything at once. See here for more info on the harms of statins.)

Fast well and reduce your chances of cancer,
