What Causes Cancer

Cancer occurs when cells grow and divide uncontrollably due to accumulated DNA damage and mutations. This is the final common pathway for all cancers.

Biological Factors

• Hereditary: Inherited gene mutations (5–10% of cancers, e.g., BRCA, Lynch syndrome).
• Obesity: Promotes inflammation and hormonal imbalance.
• Inflammation: Chronic inflammation damages DNA.
• Low Immune System: Reduces the body’s ability to eliminate abnormal cells.

Environmental Factors

• Radiation (UV from sun, medical imaging)
• Tobacco smoke, air pollution, and chemical carcinogens
• Infections (Hep B/C, HPV, H. pylori)
• Poor diet and excessive alcohol

Cancer Prevention

Key Strategies:

• Maintain healthy weight
• Regular physical activity
• Plant-based, anti-inflammatory diet
• Avoid tobacco and limit alcohol
• Get vaccinated (Hep B, HPV)
• Excellent sun protection
