No more overwhelm or confusion - finally a theory that makes sense
From my journey to yours: Understanding what really matters in cancer
Hi, I’m Mark Lintern. After facing my own diagnosis and losing a dear friend to cervical cancer, I immersed myself in the medical literature to understand the disease more deeply.
What I found revealed to me major gaps in the current interpretation of cancer – which matters, because treatment is shaped by the prevailing theory of the disease, and history shows that accepted theories can, and do, change. Seeking to explain those gaps, I spent the next eight years researching, leading to a significant theoretical breakthrough, and subsequently, the creation of a new theory proposing a different mechanism at the heart of cancer:
The Cell Suppression Theory (CST).
Searching for answers to cancer?
Providing new hope to people with cancer the Cell Suppression Theory mixes groundbreaking insight with compelling evidence to highlight the role that fungal pathogens could play in driving cancer. Mark not only provides a revolutionary new view of the disease, he translates the science in to patient-friendly terms, justifying new therapeutic options that patients can instantly adopt.
Mark's unique insight provides:
A clearer understanding of cancer
A new way to think about treatment
Confidence in navigating complex choices
Empowering patients & inspiring clinicians with Groundbreaking insight

The Cell Suppression Theory forms the foundation of my book, The Cancer Resolution?, where complex science is translated into clear, patient-friendly language without losing relevance for clinicians.
This multi-award-winning book provides clarity when it’s needed most, offering a unique perspective on the disease that may help you understand what you're facing with greater confidence - and engage in better-informed conversations with your medical team.
The best book on cancer ever written!
"Should be a MUST read by every oncologist, cancer researcher or patient. The author deserves the Nobel Prize as his view from outside of the medical field allowed him to put all the pieces of the cancer puzzle together without the medical constrictions. He debunks all the cancer theories convincingly and puts forth an excellent case for his theory of the actual cause of cancer. I won't give it away :-)). Well written and reads like a good novel. Everything is explained in layman's terms and his reasoning is easy to follow. The best book on cancer ever written!!!"

Mark is joined by Robin Daly from the cancer charity Yes to Life. In this podcast he offers insight into several established theories, and how theory can be used as a practical tool for making informed therapeutic decisions.
Mark Lintern is with Adam Payne and Kyle Drew, challenging the conventional “somatic mutation theory” of cancer and introducing his “cell suppression” framework — a meta-model that attempts to explain why cancer behaves so consistently despite highly variable mutations.

Mark's Theory
Photo by Adrian Lange on Unsplash
On 12th February 2023 Mark presented his new model of cancer to a panel of 10 international cancer experts and debated them in front of a live audience of just over 200 medical professionals, in a groundbreaking event called 'Cancer Through Another Lens'. See the image below for the panel of esteemed medical experts who took part.
During the 6-hour event, votes were cast, culminating in a favourable average score of 7.9 out of 10 in acceptance of his theory, acknowledging the profound significance of this new interpretation of the disease and the potential for it to improve survival outcomes. While this does not replace the peer-review process, it provides credibility, highlighting the scientific rigor in which Mark has conducted his research.

Current treatments are built upon underlying theories of cancer. This is a crucial point, because the fundamental cause of cancer remains unresolved. As a result, multiple competing theories exist, each proposing a different origin of the disease and, consequently, very different treatment approaches.
For both patients and clinicians, this creates an often unrecognised reality: every treatment decision is, in effect, a choice between theories. Yet most people are never made aware of this. Instead, there is a widespread assumption that medicine has already identified the correct explanation and is therefore applying the most logical and scientifically grounded treatments. In truth, without a proven, unifying cause, this certainty does not exist.
Understanding cancer theory is therefore not academic — it is the point at which meaningful decision-making begins. It provides the context needed to evaluate why a treatment is being used, what it is targeting, and whether that approach is coherent with the biology it claims to address.
The Cancer Resolution? introduces a clear and structured framework to help patients and clinicians navigate this complexity. By examining the strengths and limitations of different cancer theories, it enables a more informed and proactive approach to selecting therapeutic strategies.
Importantly, the book also presents a new theory of cancer that seeks to account for all ten hallmarks of the disease. While no theory can yet be considered definitively proven, a model that more comprehensively explains observed behaviour may offer a more coherent foundation from which to explore treatment options.
Above all, the science is translated into clear, accessible language — with the aim of equipping patients not just with information, but with a deeper understanding of the decisions they face, and the confidence to engage in them more actively.
"Are metabolic and anti-fungal therapies the solution?"
Mark Lintern
Author of the Cell Suppression Theory of cancer
This graphic illustrates the accuracy of each mainstream theory and ultimately why understanding the Cell Suppression Theory will likely benefit your overall survival. Not only does it appear to be the most accurate - indicating it has successfully identified a key driving mechanism to target - it also incorporates the treatments associated with 3 of the other leading theories, supporting a truly holistic approach to cancer care.
Using cancer theory as a practical tool for making therapuetic decisions
Which theory to choose?
After a cancer diagnosis, studying cancer theory might seem irrelevant - but it’s crucial.
Why? Because treatments are based on theory. And with at least seven different cancer theories in existence, each proposing a different cause and treatment approach, choosing the right path depends on understanding which theory is most accurate.
Most oncologists follow the DNA Mutation Theory - the idea that cancer is caused by genetic damage. Yet, this theory struggles to explain 2 of cancer’s 10 Hallmarks. That’s a weak foundation for treatment.
In contrast, the Metabolic Theory explains at least 7 Hallmarks, yet metabolic treatments are rarely discussed or offered. This raises serious concerns about the mainstream approach - and reveals that more effective options may be available.
It may seem hard to believe, but most oncologists still rely on treatments based on a flawed theory. That’s why it's essential for patients to educate themselves.
Exploring other theories not only exposes the limitations of conventional treatments but also empowers patients to take additional steps - through targeted therapies and lifestyle changes - that can improve survival prospects.
My own contribution, the Cell Suppression Theory, expands on and integrates key elements of the Metabolic, Stem Cell, and Tissue Organisation Field Theories. It’s the first to fully explain all 10 Hallmarks of cancer, suggesting it may be the most accurate theory yet - and therefore offers a promising new direction for treatment.
At minimum, this suggests I’ve uncovered a defining feature of cancer. At best, it could mean I’ve identified its root cause - an insight with the potential to transform how cancer is treated.
Since theory determines treatment, and mainstream oncology may be working from a flawed model, the responsibility to explore alternatives and build your recovery strategy may ultimately rest with you. Understanding cancer theory isn’t just helpful - it could be vital to your survival.
