Lung Cancer – Causes

According to data, nearly 90% of lung cancers are caused due to smoking. Smoking is also linked to increasing the risks of heart disease and stroke. Smoking can also trigger bronchitis.

Tobacco in any form enhances the risk of cancer. Cigarette smoke is extremely harmful to health as it contains innumerable carcinogens. The risk is manifold depending upon the quantity and duration of the habit.

The positive aspect of kicking the habit is that the risks mitigate with each year of abstaining from tobacco. This is because the body replaces the abnormal cells with normal ones.

Smoking is bad for the smoker as well as for those around, widely known as passive smoking. Passive smoking or second hand smoking is also a major cause of lung cancer. It is disheartening to observe that smoking has become popular among women too, irrespective of their geographical background.

Flavored tobacco, used in hookahs are highly popular among men and women in several Asian countries. It is promoted under the pretense of being mild and not harmful. Smoking in any form is indeed injurious-the ‘baccy’ being flavored or not!

Exposure to carcinogens in the atmosphere as part of ones occupation is a significant cause of this disease. In this aspect, asbestos has been in the news as a risk factor for lung cancer. Pollution in the atmosphere also enhances the risk of lung cancer.

Occupational hazards coupled by bad lifestyle choices like smoking can simply magnify the risks of lung cancer.

Types of Lung Cancer

Lung cancer can be of two types - non-small cell lung cancer and small cell lung cancer. Incidence of Non small cell lung cancer is high as compared to small cell lung cancer.

Oat cell cancer, another name for small cell lung cancer is responsible for about 20% of lung cancer cases.
