One of the most frequent types of cancer encountered nowadays is the lung cancer. Statistics say that every year approximately 40,000 people in the UK die from lung cancer so you can imagine how dangerous this affection is. In the USA lung cancer affects 99,000 men and 78,000 women every year and from all of them 86% die during the first years since they were diagnosed with cancer.

Researchers say that the main cause of lung cancer is tobacco smoke. Smoking seems to increase the risk of developing lung cancer ten times more than in non smokers. It is true that non smokers can develop lung cancer too, but this is happening due to other risk factors that can affect them. As the tobacco industry and marketing have been developing more and more during the last 50 years it is not surprisingly that nowadays a lot of lung cancer cases are being detected.
