Episode notes
Cancer Cell Characteristics
- Cancer cells can self-renew and evade differentiation, unlike normal cells.
- They proliferate continuously, migrate, and are driven by oncogenes, often requiring two or more cooperating oncogenes to develop.
Seed and Soil Analogy in Cancer
- Cancer development depends on both genetic predisposition ("seed") and environmental factors ("soil").
- Factors like chronic stress and a compromised immune system can create a favorable environment for cancer growth.
Cancer Risk Factors
- Environmental factors and personal choices influence cancer risk.
- Radiation exposure (sunlight, x-rays) and dietary habits (red meat consumption) can increase cancer risk.
