A new study from South Korea has documented how COVID shots and their boosters, mandated by corporations, military commanders, federal officials and more during the pandemic created by the China virus, push up the risk of cancers.

A report at Childrens Health Defense cites the study by South Koreans published in Biomarker Research, a Springer Nature journal.

The study included more than eight million people and found COVID-19 shots and boosters "are associated with a higher risk of breast, colorectal, gastric, lung, prostate and thyroid cancer, across all vaccine types and age groups."

"Mainstream medical commentators" claimed the findings are "flawed."

But others found value in the results.

"In plain terms: both major COVID-19 vaccine platforms appear to be carcinogenic," epidemiologist Nicolas Hulscher wrote in a post on Substack.

Those would be mRNA and non-mRNA.

Dr. Angus Dalgleish, a medical oncologist, told The Defender the study builds on other recent findings but 'is the first to show that cDNA [non-mRNA] and mRNA vaccines are associated with cancer risk, suggesting that the spike protein is directly carcinogenic,'" the report said.

The report noted, "The researchers said the 'shared structures' contained within the SARS-CoV-2 virus and the COVID-19 vaccines, including the spike protein, might mean that the COVID-19 shots are associated with cancer risks."

The data comes from some 8.4 million people in South Korea's National Health Insurance Service database. And researchers tracked patients for a year, after dividing them in vaccination status groups, and found the overall cancer risk among those given shots was 27% higher.

For breast cancer, the risk was 20% higher, 28% higher for colorrectal cancer, 34% higher for gastric cancer, 53% higher for lung cancer and 69% higher for prostate cancer.

The report said, "COVID-19 mRNA vaccines produced by Pfizer and Moderna showed a 20% higher overall risk of cancer and were most closely linked to a higher risk of breast, colorectal, lung and thyroid cancers. Non-mRNA COVID-19 vaccines, known as cDNA vaccines and which include the AstraZeneca and Johnson & Johnson (Janssen) shots, were associated with a 47% higher overall risk of cancer. They were specifically linked to an increased risk of colorectal, gastric, lung, prostate and thyroid cancers."

Hulscher confirmed, "The elevated cancer risks were not confined to one vaccine platform. Each vaccine type was associated with a measurable increase in overall cancer — and each had specific cancer sites driving the signal. In other words, no vaccine technology was free of cancer risk in this dataset."

Hulscher wrote: "Both the overall and site-specific results show a consistent pattern — every demographic group experienced elevated cancer risks, though the type and absolute burden varied. Women and the elderly were hit hardest, but no population segment was spared."

Critics charged the study failed to account for family histories of cancer, and screening histories.

But Children's Health Defense research scientist Karl Jablonowski explained, "The criticism levied against the study is of healthy user bias. The idea that people more likely to engage in one medical intervention (vaccination) are also more likely to engage in another (cancer screening) … is a valid concern for a vaxed-unvaxed study such as this one, as those seeking a vaccine will have drastically different healthcare-seeking behavior than those not seeking a vaccine.

"[However,] this is not just a vaxed-unvaxed study — it also differentiates the vaccines. Healthy user bias is not a point of argument for why one vaccine (cDNA) shows a strong cancer risk above another (mRNA). Further, the study doesn't say vaccines cause cancer, but are associated with them."
