Definition of Cancer Group of diseases characterized by
uncontrolled growth and spread of mutated cells
Normal /Cancer Cells
MAIN CAUSES OF CANCER1. Heredity2. Acquired
environmental factors
Causes of Cancer INTERNAL *internal
mutations *hormones *immune
conditions
EXTERNAL *tobacco *Infections
organisms *Chemicals *radiation
Environment- Behavioral Choices (87%) Tobacco use Poor nutrition Physical inactivity Obesity Infectious agents Medical treatments Excessive exposure to sun Exposure to pollutants in air, H2O, food,
soil
Recommendations Maintain and achieve a healthy weight
throughout life. Adopt a physically active lifestyle Consume a healthy diet w/emphasis on
plant foods. Limit consumption of alcohol. No smoking
Foods Link to Cancer Battle between
free radicals and antioxidants.
Free Radicals are molecules with incomplete electron shells.
The free radical attacks the nearest stable electron – stealing its electron.
Free radicals are formed:
1. during metabolism2. by immune system when fighting infection3. radiation, pollution, cigarette smoke, herbicides.Free radical damage accumulates with age.
Antioxidants Neutralize free radicals by donating one
of their electrons. This prevents cell and tissue damage
that could lead to disease.
