Relative Risk is defined as a measure of the strength of the relationship between a risk factor and a particular cancer. It compares the risk of developing cancer in persons with a certain exposure or trait to the risk in those who do not have this exposure or trait. With tobacco and lung cancer, relative risk compares the risk of developing lung cancer in smokers to the risk in those who do not smoke. For example, current male smokers have a 22.4-fold increased risk of developing lung cancer compared to men who have never smoked. This means that men who are smoking are about 22 times more likely to develop lung cancer than men who do not smoke.
