Rates of Colorectal and Other Cancers Are Rising in Young Adults, Puzzling Researchers

Incidence of 14 cancer types increased among people younger than 50 years.

9 of those cancer types, including colorectal cancer and breast cancer, also increased in some over 50s.

Factors

Increased imaging

But, many early-onset colorectal tumors diagnosed after symptoms

“Given that similar trends have been observed in the US and many other countries, it’s crucial for researchers to address how much of this is driven by shifts in risk factors versus changes in diagnostic practices,”

38,604 patients
New diagnosis

2021 to 2022 = 35,779

2022 to 2023 = 38,604

By October 2020, monthly diagnoses had returned to pre-pandemic levels,

from April 2021 the number of monthly diagnoses continued to rise.

The total number of patients diagnosed with colorectal cancer during 2021/22 surpassed annual figures prior to the COVID-19 pandemic.

The potential for mRNA vaccines to cause cancer

Theoretical mechanisms

DNA Integration

mRNA or fragments, reverse transcriptase, potentially disrupting tumour suppressor genes or activating oncogenes

DNA contamination, integrate into the genome

Contaminants in Vaccine Production

Pfizer COVID-19 modRNA vaccines also contained an SV40

Inactivated tumour suppressor genes, p53 and Rb, promoting unchecked cell growth

Prolonged Spike Protein Expression

N1-methyl-pseudouridine-modified mRNA encoding the SARS-COVID-19 Spike protein

Lipid nanoparticle (LNP) delivery to stem cells

Sustained spike protein production,

induce chronic inflammation,

disrupt cellular repair mechanisms.

Immune Suppression or Dysregulation

Molecular Mimicry, Autoimmunity, inflammation

Alter regulatory T-cell function, (potentially allowing pre-existing cancers to progress).

(If the spike protein shares epitopes with tumour suppressor proteins)
