• Contain preservatives, additives, and trans fats
• Linked to colorectal, breast, and stomach cancers

Red & Processed Meat

• Red meat (beef, pork) and processed meat (sausages, bacon, salami)

• Increases digestive system cancer risk

Lifestyle Habits That Promote Cancer

• Linked to lung, mouth, throat, bladder, and pancreatic cancers

Excess Alcohol Consumption

• Associated with liver, breast, esophageal, and mouth cancers

Physical Inactivity

• Increases obesity-related cancer risk

Obesity & Poor Metabolic Health

• Causes chronic inflammation and hormone imbalance
• Linked to breast, uterine, colon, kidney cancers

Poor Sleep & Chronic Stress

• Disrupts hormones and immune repair
• Long-term stress weakens cancer defense mechanisms

Other Risk-Enhancing Behaviors
