1st August is World Lung Cancer Day. Let’s take this opportunity to discuss some facts about lung cancer. The rapid division of the cells of the lungs in an uncontrollable way leads to this cancer. It can often spread to lymph nodes and other organs in the body. There are occasions when cancer spreads to the lungs from other organs. Non-small cell and small cell are its two types. The growths of these two types are different. The cases of non-small cell lung cancer are more than those of small cell lung cancer. You will get effective lung cancer treatment in Howrah.

Risk Factors                                                  

The risk of developing lung cancer becomes more due to the following factors:

    Asbestos, arsenic, silica, chromium and diesel exhaust present in some workplaces can cause this cancer.
