Lung cancer is a disease that begins in the
lungs, two soft, spongy organs located in the chest that absorb oxygen when you breathe in
and release carbon dioxide when you breathe out. Lung cancer is the leading cause of
cancer-related deaths worldwide.
Smoking is the primary risk factor for lung cancer, and the risk increases with the number
of cigarettes smoked and the length of time a person has smoked. However, lung cancer can
also develop in people who have never smoked, due to factors such as environmental exposure,
air pollution, or genetic susceptibility.
Early diagnosis and timely treatment play a crucial role in improving survival rates for
lung cancer patients.
