Lung Cancer: Causes and Treatment

Lung cancer is a life-threatening disease that mainly occurs due to smoking and air pollution. It involves the abnormal growth of lung cells and the formation of tumors, which can spread throughout the body.

Causes:

Smoking: This is the primary cause of lung cancer. People who smoke for a long time are at higher risk of developing this cancer.

Secondary Smoke: Being around smokers and indirectly inhaling the smoke also increases the risk.

Air Pollution: Exposure to polluted air and chemical substances can also cause cancer.

Genetic Factors: A family history of cancer increases the risk.

Radiation: Exposure to excessive radiation is also risky.
