Non-communicable diseases, risk factors and other medical conditions brought on by lifestyle

e.g. cancer, diabetes, heart diseases (cardiovascular of the circulatory system), kidney disease or respiratory diseases of the lung like emphysema and bronchitis, legal and illegal drugs, solvents, alcohol and lifestyle choices

Doc Brown's biology exam revision study notes

 What is a non-communicable disease?   

Describe some examples on non-communicable diseases.   Explain some life-style risk factors associated with cancer. What is an illegal drug? Why are some drugs so harmful? Why are solvents and alcohol harmful?
