This study was done in the province of Pescara, Italy involving about 300,000 residents. It was conducted from June 2021 through December 2023 and published in July 2025. It is consistent with other reports over the past few years showing an increased risk for cancer from COVID shots. Here are some of its findings.
Overall cancer risk increased 23% (HR 1.23, 95% CI 1.11-1.37).
Breast cancer risk increased 54% (HR 1.54, 95% CI 1.10-2.26).
Bladder cancer risk increased 62% (HR 1.62, 95% CI 1.07-2.445).
Colon-rectum cancer risk increased 35% (HR 1.35, 95% CI 1.01-1.80).
The following cancers had increased risk with COVID shots but were not statistically significant: hematological, uterine, ovarian, thyroid, and prostate.

In a previous study published in 2024, Akkus et al demonstrated a link between the COVID shots and colon cancer.

In particular, the authors studied microsatellite instability-high (MSI-H) colon cancer, named because of the instability of the tumors cells due to genetic mutations. The study ran from June 2021 through June 2023 and was published in June 2024. Two COVID shots were used: Pfizer and CoronaVac. CoronaVac was an inactivated SARS-CoV-2 virus vaccine developed in China and available to several countries during the pandemic including Turkey.
The Pfizer shot was associated with a greater than 500% increased risk of developing MSI-H colon cancer (OR 6.39, 95% CI 1.55-26.26, p = 0.01).
No such increased risk was found with CoronaVac.

Finally, there is a recently published paper by Marik et al, COVID-19 mRNA-Induced “Turbo Cancers”. How do these shots cause cancer? The authors review the mechanisms involved. At the end of the paper, they offer suggestions for preventative measures.
