The COVID Advisor

COVID-19 vaccines and boosters — both mRNA and non-mRNA — pose an increased risk of six types of cancer and a   27% higher risk of cancer overall , according to a recent South Korean study of over 8 million people. Four South Korean researchers published the report last week as a letter in Biomarker Research, a Springer Nature journal. According to the study, COVID-19 vaccines 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 were quick to dismiss the findings, with  MedPageToday  describing it as “flawed.” But other medical and scientific experts disagreed. “In plain terms: both major COVID-19 vaccine platforms  appear to be carcinogenic ,” epidemiologist Nicolas Hulscher wrote in a post on Substack. Dr. Angus Dalgleish , a medical oncologist, told  The Defender ...

Abstract The term "turbo cancer" describes purported aggressive, rapidly progressing cancers allegedly induced or exacerbated by COVID-19 vaccines, particularly mRNA formulations. This narrative review synthesizes evidence from observational studies, mechanistic hypotheses, case reports, and counterarguments to assess its validity. A recent 2025 review by Marik and Hope in the Journal of Independent Medicine details epidemiological trends, VAERS data, and proposed mechanisms linking SARS-CoV-2 spike protein to oncogenesis via metabolic reprogramming, immune disruption, and other pathways. Proponents cite associations from large-scale databases, anecdotal reports, and biological plausibility, while critics highlight methodological flaws, biological implausibility, and alternative explanations such as pandemic-related healthcare disruptions. As of October 2025, observational data reveal associations.  While the prognosis of these cancers...
