Microbes, macrophages, and melanin: a unifying theory of disease as exemplified by cancer

Sep 23, 2026

Uploaded by Hazel

Proposes a paradigm shift in cancer causation, challenging the random somatic mutation theory by arguing cancer is a targeted survival strategy of pathogens. Presents tumors as complex microbial communities within biofilms embedded in a hard matrix, where microorganisms drive genetic mutations and regulate angiogenesis. Suggests pathogens disseminate by hiding in tumor and M2/M2-like macrophages and other phagocytic immune cells, using melanin for energy to build tumors and metastases, and shaping treatment and prevention trajectories.

Berg* and Jonathan Berg* Department of Translational Biology, William Edwards LLC, Baltimore, MD, United States It is widely accepted that cancer mostly arises from random spontaneous mutations triggered by environmental factors. Our theory challenges the idea of the random somatic mutation theory (SMT) . The SMT does not ﬁt well with Charles Darwin’s theory of evolution in that the same relatively few mutations would occur so frequently and that these mutations would lead to death rather than survival of the ﬁttest. However, it would ﬁt well under the theory of evolution, if we were to look at it from the vantage point of pathogens and their supporting microbial communities colonizing humans and mutating host cells for their own beneﬁt, as it does give them an evolutionary advantage and they are capable of selecting genes to mutate and of inserting their own DNA or RNA into hosts. In this article, we provide evidence that tumors are actually complex microbial communities composed of various microorganisms living within bioﬁlms encapsulated by a hard matrix; that these microorganisms are what cause the genetic mutations seen in cancer and control angiogenesis; that these pathogens spread by hiding in tumor cells and M2 or M2-like macrophages and other phagocytic immune cells and traveling inside them to distant sites camouﬂaged by platelets, which they also reprogram, and prepare the distant site for metastasis; that risk factors for cancer are sources of energy that pathogens are able to utilize; and that, in accordance with our previous unifying theory of disease, pathogens utilize melanin for energy for building and sustaining tumorsand metastasis. We propose a paradigm shift in our understanding of what cancer is, and, thereby, a different trajectory for avenues of treatment and prevention.

In 2020, there were nearly 10 million cancer deaths (3) . Cancer is conventionally thought to be caused by random genetic mutations. We propose here a paradigm shift in our understanding of what cancer is, Frontiers in Immunology 01 [frontiersin.org](frontiersin.org) and thereby a different trajectory for avenues of treatment, preventi

FAQs

What theory does the article challenge, and what does it propose instead?

It challenges the random somatic mutation theory of cancer. It proposes that certain microorganisms use cancer as a targeted strategy to survive and thrive.

How does the article describe the composition of tumors?

Tumors are described as complex microbial communities composed of various microorganisms living within biofilms encapsulated by a hard matrix.

How does the article explain how pathogens spread to cause metastasis?

It proposes that pathogens spread by hiding in tumor cells and M2 or M2-like macrophages and other phagocytic immune cells, traveling to distant sites camouflaged by platelets and preparing those sites for metastasis.
