During the mass mRNA injection campaign, multiple cancer types rose sharply among Americans under 50
The official cancer numbers are in — and they are raising concern.
According to the National Cancer Institute’s latest SEER data release:
https://seer.cancer.gov/statistics-network/explorer/application.html?site=1&data_type=1&graph_type=2&compareBy=age_range&chk_age_range_9=9&rate_type=2&sex=1&race=1&hdn_stage=101&advopt_precision=2&advopt_show_ci=on
Cancer incidence rates among Americans under age 50 increased 6.4% between 2021 and 2023.
This includes notable rises in:
- Colon and rectal cancer (+19.4%)
- Brain tumors (+19.5%)
- Small intestine cancer (+15.5%)
- Ovarian cancer (+12.8%)
- Stomach cancer (+7.3%)
- Breast cancer (+3.6%)
All Cancers Combined (Age < 50)
- 2021: 109.45 per 100,000
- 2023: 116.42 per 100,000
- +6.4% increase in two years

Largest Increases by Cancer Type (2021–2023)
- Brain tumors: 6.72 → 8.03 per 100,000 (+19.5%)
- Colon & rectal cancer: 9.62 → 11.49 per 100,000 (+19.4%)
- Small intestine: 0.71 → 0.82 per 100,000 (+15.5%)
- Ovarian cancer: 4.21 → 4.75 per 100,000 (+12.8%)
- Stomach cancer: 1.65 → 1.77 per 100,000 (+7.3%)
- Breast cancer: 49.95 → 51.75 per 100,000 (+3.6%)

Increase by cancer type
Early-onset cancers were already rising gradually over time, but the post-2021 acceleration is significant.
The timing aligns with the period of widespread mRNA vaccination campaigns.
Supporting Research
A 30-month population study of 296,015 residents in Italy found:

- 23% higher likelihood of cancer-related hospitalisation among vaccinated individuals
- Elevated risks for colorectal, breast, and bladder cancers

Population-wide study results
A separate South Korean study involving over 8.4 million individuals found increased 1-year risks across six major cancers:

- Thyroid
- Gastric
- Colorectal
- Lung
- Breast
- Prostate
Mortality Trends
Independent analysis of CDC WONDER data suggests:

- Over 138,000 excess cancer deaths in the U.S.
- Clear inflection point beginning in 2021

Excess cancer mortality trend
Key Takeaway
The data indicates:
- A measurable rise in early-onset cancers
- Acceleration beginning post-2021
- Consistency across multiple datasets and studies
While causation is not established, the correlation is drawing increasing scrutiny and debate.
