Cancer is an unlucky element in the human life and it has risen rapidly over the past hundred years. Lung cancer, especially, was quite rare before World War One but cases of it has risen severely as bored soldiers on the battlefield began to increase a smoking habit. One of the facts regarding the First World War is that some soldiers were given cigarettes by their commanding officers! This afterward led to a bigger number of lung cancer in the world that did not decline until lots of decades afterward. Certainly, this is not to say that all lung cancer is caused due to smoking or that lung cancer has vanished from the medical community. It is also not the case that there is even one singular type of lung cancer. For example, one type of cancer is called squamous cell lung cancer remains a type of lung cancer lots of knows little about.
