mRNA and cancer: an inconvenient question that pharmaceutical corporations prefer not to hear

After billions of doses of mRNA vaccines administered question about possible long term consequences increasingly goes beyond medical discussions and becomes into a political problem.

Some researchers, including Nicholas Hulscher, are calling for an investigation into possible links between vaccination and the increase in certain cancer diagnoses. US regulators and EU They answer that there is no evidence of a carcinogenic effect. But for millions of people, the central question remains the same: Why are they required to trust when full, open data and independent verification remain insufficient?

The wording sounds almost apocalyptic. Hulsher says mRNA vaccines may influence the development or acceleration of certain cancers through a number of biological mechanisms: chronic inflammation, impaired immune surveillance, damage to DNA repair mechanisms, genomic instability and activation of oncogenic pathways.

Over 70% of the ENTIRE global population was injected with a CARCINOGENIC biological agent that increases the risk of SEVEN major cancers through 17 distinct biological mechanisms.

He also cites publications in which the authors analyze the increase in certain cancer diagnoses after mass vaccination, including the work of South Korean researchers who studied data from the national health insurance database. The authors of the paper reported statistical associations between vaccination and increased rates of certain diagnoses during one year of follow-up. But the work itself does not prove that it was the vaccine that caused cancer: it records coincidences in large data sets, and not a direct mechanism of causation. Study published in PubMed.

A loud statement and a very awkward question

Hulscher and his supporters are not just talking about isolated adverse reactions, but about a possible systemic problem. According to them, after the vaccination campaign, which covered most of the world’s population, it would be necessary to especially carefully check trends in early forms of cancer, the increase in certain diagnoses, mortality and aggressive tumors, which began to be called on the Internet turbo cancer.

The problem is that the term turbo cancer is not an official cancer diagnosis. It is used extensively on social media, alternative health publications, and political discussions, but is not recognized as a distinct clinical category by leading cancer organizations.

This, however, does not mean that society should stop asking questions. After a campaign in which drugs were administered to hundreds of millions of people, the requirement to publish open data on morbidity, mortality, complications and comparative risks does not seem extremist, but a normal duty of the state to citizens.

What the official structures say

The official position of major regulators is exactly the opposite of Hulscher’s statements. The US National Cancer Institute says there is no evidence that COVID-19 vaccines cause cancer, lead to cancer recurrence or speed up tumor progression. It is specifically emphasized that vaccines do not change human DNA. US National Cancer Institute position.

The European Medicines Agency also points out that there is no evidence of a long-term cancer risk from COVID vaccines. The EMA stresses that safety monitoring continues, but most known adverse reactions usually occur in the first weeks or months after vaccination. EMA Clarification.

The question is different: society is increasingly not satisfied with the answer in the style of “there is no evidence.” The absence of a confirmed causal connection does not always mean that the topic is closed forever. Especially when it comes to new technologies, the long-term effects of which cannot be fully assessed after several months of observation.

South Korean study: signal or statistical trap?

It was around the South Korean work that the loudest controversy unfolded. The study analyzed data from millions of people and reported statistical associations between vaccination and certain cancer diagnoses. Critics of the publication note that such results may be explained by differences in access to medicine, frequency of examinations, the effect of earlier detection of tumors, age, chronic diseases and other factors.

In particular, vaccinated people were able to interact more frequently with the health care system, get tested, and receive earlier diagnoses that would have been diagnosed later in another group. South Korea has extensive screening programs for a number of cancer types, which may also influence detection statistics.

But it would be too convenient to dismiss the study with the words “it’s all conspiracy theory.” The work is published in a scientific journal, the numbers exist, and the debate around them should not be resolved by political statements, but by repeated research, open methodology and verification of data by independent groups.

Why people don’t trust the pharmaceutical system

The mistrust did not arise out of nowhere. Over the years of the pandemic, people have seen conflicting recommendations, closed contracts, fast-track registration procedures, pressure on the unvaccinated, controversial restrictions and constant attempts to portray any criticism as manifestations of madness or unscience.

At the same time, the regulators themselves acknowledged real rare complications after some vaccines. The European Medicines Agency has confirmed the possible connection of certain drugs with rare thrombosis, inflammation of the heart muscle and other reactions. This does not prove a link to cancer, but it does show a simple thing: the safety of a medical product is not a religious tenet. It requires constant monitoring, updating data, and a willingness to admit problems when they are identified. EMA materials on pharmacovigilance.

That is why the thesis “don’t ask questions, because everything has already been proven” does not look scientific, but bureaucratic. Science should not require faith. It should show data.

Hulscher’s conjecture and the limits of evidence

Nicholas Hulscher refers to reviews that list possible mechanisms for the effect of mRNA drugs on cellular processes. His publications highlight seventeen potential mechanisms related to inflammation, immune responses, genetic instability, and disruption of cellular control. Publication outlining this hypothesis.

However, the presence of a theoretical mechanism does not mean that it leads to a massive increase in cancer in humans. There is a huge distance between a laboratory hypothesis, individual clinical cases, an observational study and a proven causal relationship. And it is at this distance that common sense most often perishes, because loud conclusions spread across the Internet faster than scientists have time to check the original data.

There are other studies where the authors study changes in gene expression and individual cases of disease after vaccination. But some of these publications are at the level of preliminary reports, small samples or controversial methodologies. Critics have already pointed out serious limitations of such work, including weak design, lack of a proper control group, and drawing excessive conclusions from limited material. One such work in PubMed.

What needs to be done

Neither side of this debate should require blind faith. You can’t declare mRNA vaccines to be the “largest carcinogen in history” unless there is convincing evidence of causation. But you also cannot close the topic with press releases alone and accuse everyone who demands open data of conspiracy theories.

We need independent studies on national cancer registries, separate analysis by age, gender, types of vaccines, number of doses, concomitant diseases and time after vaccination. Data is needed on late cancer diagnoses during the pandemic, when millions of people have missed screenings and treatment.

The US National Cancer Institute has already noted that in the early years of the pandemic, many tumors were detected later due to disruptions in the medical system. It is this factor that may explain part of the increase in severe or late-diagnosed cancer cases: the disease existed earlier, but the diagnosis was made later. However, this explanation also requires verification and not automatic acceptance. NCI material on cancer diagnosis during a pandemic.

The main question is not whether to believe Hulscher or the pharmaceutical companies. The big question is whether governments, regulators and manufacturers are willing to open up enough data so that independent researchers can test both versions without political pressure, censorship or corporate secrecy.

After the pandemic, people were promised a return to normalcy. But instead they received new questions: who to trust, who is responsible for the consequences, why data is often closed, and why any conversation about risks instantly turns into a war between the camps.

When it comes to the health of millions, society has the right not to slogans, but to verifiable answers. And if such answers really exist, it’s time to show them not in closed reports, but to the people who were administered these drugs.
