The COVID Advisor

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...

As discussions around COVID-19 vaccines and long-term health effects continue to evolve, a 2025 South Korean study has sparked interest by suggesting associations between vaccination and elevated risks for certain cancers. Published in Biomarker Research, this large-scale cohort analysis of over 8.4 million people found vaccinated individuals had a 27% higher overall cancer risk compared to unvaccinated ones, with specific increases in prostate (68%), lung (53%), gastric (34%), thyroid (35%), colorectal (28%), and breast (20%) cancers. Boosters were linked to even higher risks for pancreatic (125%) and gastric (23%) cancers, affecting all demographics but more pronounced in women, the elderly, and across both mRNA and non-mRNA vaccines. Potential mechanisms include the spike protein's role in inflammation or carcinogenesis, though the study emphasizes the need for further research and does not prove causation. However, critics argue the study's one-year follow-up is too short...
