  • Non - communicablediseases
    • Non comunicable diseases
      • A non communicable,endisease vant be passed form one individual to another
      • risk factors are aspects of a persons lifestyle of substances present in a body or environment that have been shown to Ben linked to an increased rate of disease
        • For some non communicable diseases a causal mechanism from some risk factors has been proven but not in others
    • Cancer
      • Beign and malignant tumours result from abnormal uncontrolled cell division
      • Benign tumours form in one place and spread to other tissues
      • Malignant tumour cells are cancerous
        • They invade neighbouring tissues and may spread to diffrent parts of the body where they form secondary tumours
      • There are many diffrent life style risks that can't cause cancer
        • These could be smoking obesity common virus and UV exposure
          • There are also genetic risk factors for some cancers
    • Smoking and the risks of disease
      • Smoking can cause cardi vascular disease
        • These could include coranry heart disease lung cancer and lung diseases such as bronchitis and COPD.
      • A foetus exposed to smoke has restricted oxygen
        • Which can lead to premature birth, low birth weight and even still birth
    • Diet, exercise and disease
      • Obesity is a strong risk factor for type 2 diabetes
      • Your diet affects your risk of developing cardio vascular and other diseases directly through cholesterol levels and indirectly through obesity
      • Exercise levels affect the likelihood of developing through obesity
    • Alcohol and other cargiogens
      • Alcohol can cause brain damage and death
      • Alcohol can damage the liver if you drink to much and to often, i can cause cirrhosis and liver cancer
      • Alcohol taken in by pregnant women can affect the development of her unborn baby
