Lung Cancer

In my opinion, Lung Cancer is the biggest problem for most of people.Because of smoking, second-hand smoked or other reasons, that's why our respiratory getting worse.

Lung Cancer is made of many bad components. Such as, smokers might be have nicotine deposits of the lung, so it will beging to become the cancer cells.
But that may be is ten years later because it need to have time to accumulation. Everybody have chance to get the Lung Cancer not only the elder people, it depends on different kinds of physique.Some people are non-smoker but they still will get the Lung Cancer, that might be too much second-hand smoked or like a house wife. Because they have to cook quite often and when they are cooking, it will make some lampblack. It also can make our respiratory have some problems, but smoking is the biggest reason to get the Lung Cancer.
