Lung Cancer

The lungs, a pair of spongy conical organs and are part of the respiratory system. The right lung has three lobes and left lung has two lobes. Fresh oxygen is brought to the body and excess carbon-di-oxide removed through lungs.

Risk factors for Lung Cancer:

Cigarettes, Cigars and Pipes- Smoking cigarettes causes lung cancer.  'Smoking is the single largest cause of lung cancer'. Stopping smoking greatly reduces a person's risk for developing lung cancer. Involuntary or passive smoking also greatly increases the risk of lung cancers.

Asbestos- Inhalation of asbestos particles can damage lung cells and increase the risk for lung cancer. Workers who have been exposed to large amounts of asbestos have a risk of developing lung cancer that is 3 to 4 times greater than that for workers who have not been exposed to asbestos. Asbestos exposure can lead to Mesothelioma - A malignant tumor of pleura, peritoneum or pericardium.

Radon- Radon is an invisible, odorless, and tasteless radioactive gas that occurs naturally in soil and rocks. It can cause damage to the lungs that may lead to lung cancer. Risk is relatively high in miners exposed to radon

Pollution- A link between lung cancer and exposure to certain air pollutants, such as by-products of the combustion of diesel and other fossil fuels is probable but not yet clearly established.

Lung Diseases- Chronic lung diseases like tuberculosis (TB) can increase a person's chance of developing lung cancer.

Past History- Increased risk of lung cancer developing in a person who had a past history of Lung cancer.
