Lung cancer is quite common in India. It is caused by uncontrolled growth of abnormal cells in one or both lungs. These cells can interfere with the lung's function of providing oxygen to the whole body (via blood). Abnormal cells in lungs can also lead to the formation of a tumour. Read below to know some of the top symptoms and risk factors of lung cancer and what you can do about them.

The top five risk factors that can increase lung cancer:

1. Smoking: The number of cigarettes you smoke each day along with the number of years you have smoked increases your risk of lung cancer. You can lower your risk of developing lung cancer by quitting at the earliest.

2. Family history of lung cancer: People with a child, sibling or parent with lung cancer have an increased risk of the disease.

3. Exposure to second-hand smoke/passive smoking: Your risk of lung cancer increases if you're exposed to second-hand smoke (even if you don't smoke).

4. Exposure to mineral carcinogens like asbestos:Carcinogens are substances, which are capable of causing cancer in a living tissue. Exposure to asbestos and substances at workplace (like arsenic, nickel and chromium) can increase your chance of developing lung cancer (especially if you're a smoker).

5. Exposure to radioactive gas: Also know as radon gas, this is produced by the natural breakdown of uranium in soil, rock and water, eventually becoming a part of the air you breathe. Unsafe levels of radon gas can assemble in any building, including homes. People in jobs that involve being close to industrial waste or fumes may be at risk of lung cancer.
