Episode notes
Vaccines Prevent Significant Virus Linked Cancers
- Vaccines can prevent virus-driven cancers; hepatitis B and HPV vaccines already avert many future cases.
- Erin Welsh highlights EBV causes hundreds of thousands of cancers but currently lacks an available vaccine.
Use Screening Only When It Meets Proven Criteria
- Follow established screening guidelines because tests must meet reliability, harm, and treatment-effectiveness criteria before routine use.
- The WHO Wilson criteria require that screening yields more effective pre-symptomatic treatment and clear policies for who gets treated.
Knowledge Alone Does Not Reduce Cancer Burden
- Knowledge of cancer causes and tools doesn't ensure reduced burden; structural inequalities block equitable benefit.
- Erin Welsh stresses that access, education, and political will determine who benefits from advances.
