Cancer of lung is known as lung cancer and it can happen in both male and female. There are major two types of lung cancer namely small cell lung cancer and non-small cell cancer. In comparison to small cell lung cancer the non-small cell lung cancer is very much common as it generally grows and spreads more slowly to the different parts of the body. The small cell lung cancer is also known as oat cell cancer. In the early stage of the lung cancer does not causes any kind of symptoms. Thus it becomes hard to diagnose it in the early stage. Around 70% of the lung cancer is diagnosed in the advanced stage and thus reduces the chance of long term survival.
