Smoking is cited as the number one cause of lung cancer. Cigarette smoke contains about 4000 different chemicals all of which are known to be carcinogenic or cancer causing. The risk of lung cancer in smokers is directly proportional to the number of cigarettes one smokes. The more one smokes, the greater the risk of developing lung cancer. Smoking not only brings about a lot of chemical changes in the brain but it also affects all the organs in the body. Smoking can lead to heart disease, respiratory problems, aggravate asthma and many more. One cigarette can have a really bad affect on one’s health.

Once a person stops smoking the risk of developing lung cancer not only drops drastically but it also replaces the damaged cells in the lung with new and normal cells.

Not only do the chemicals in the smoke affect the lungs and develop cancer but they are also known to cause other respiratory disorders like bronchitis and emphysema and also heart disease. Not only is the primary smoker affected with this but the non-smoker inhaling this can also be affected and secondhand smoking is also known to cause lung cancer.

Lung cancer takes many years to develop but the changes that take place in the lung can start almost as soon as the person is exposed to carcinogenic substances or cancer causing chemicals. The development of these abnormal cells may keep increasing if the person is exposed to these cancer causing agents continuously and they in turn may become cancerous and form a tumor.

Once cancer has been detected in the lungs then the treatment for it is, like most other cancer treatments, through surgery, chemotherapy or radiation.

The best way to prevent this from happening is to stop exposing your lungs to these cancer causing agents and try to work through a carcinogen free atmosphere. Since it has been found that smoking is one of the leading causes of lung cancer, quitting smoking can be one of the primary ways to not develop lung cancer.
