What are the causes of lung cancer deaths?

Lung cancer is one of the leading causes of death worldwide, claiming more lives than any other form of cancer. According to the World Health Organization, lung cancer caused 1.76 million deaths in 2018 and accounted for 18% of all cancer deaths - more than twice that of colorectal, breast, and prostate cancer combined.

The primary cause of lung cancer is tobacco smoking or exposure to secondhand smoke from cigarettes or cigars. Over 80% percent of all cases are linked to smoking and passive smoke exposure. In fact, smokers are 15-30 times more likely at risk for developing lung cancer compared non-smokers according to The National Cancer Institute (NCI). Other potential factors that contribute to increased risk include air pollution from smog/vehicles; occupational hazards like asbestos, arsenic and other hazardous chemicals; radon gas in homes; certain infections like human papillomavirus (HPV); a family history or genetic predisposition; as well as radiation therapy used for treating prior cancers like Hodgkin’s lymphoma can increase the chance for developing new cancers.

Despite these risks though, research shows bringing attention on preventive measures such as quitting smoking can still reduce the number of deaths due to lungcancer substantially over time. With continued support from government health organisations, NGOs & public education initiatives aimed at reducing cigarette use globally there is hope we can continue making strides towards decreasing these tragic numbers even further in years ahead – but only if we stay committed today!
