Passage: Worldwide, lung cancer is the most-common cancer among men in terms of both incidence and mortality, and among women has the third-highest incidence, and is second after breast cancer in mortality. In 2012, there were 1.82 million new cases worldwide, and 1.56 million deaths due to lung cancer, representing 19.4% of all deaths from cancer. The highest rates are in North America, Europe, and East Asia, with over a third of new cases in China that year.  Rates in Africa and South Asia are much lower.The population segment that is most likely to develop lung cancer is people aged over 50 who have a history of smoking. Unlike the mortality rate in men – which began declining more than 20 years ago, women's lung cancer mortality rates have risen over the last decades, and are just recently beginning to stabilize. In the US, the lifetime risk of developing lung cancer is 8% in men and 6% in women.For every 3–4 million cigarettes smoked, one lung cancer death can occur. The influence of "Big Tobacco" plays a significant role in smoking. Young nonsmokers who see tobacco advertisements are more likely to smoke. The role of passive smoking is increasingly being recognized as a risk factor for lung cancer, resulting in policy interventions to decrease the undesired exposure of nonsmokers to others' tobacco smoke.In the US, both black men and black women have a higher incidence. Lung cancer rates are currently lower in developing countries. With increased smoking in developing countries, the rates are expected to increase in the next few years, notably in both China and India.Also in the US, military veterans have a 25–50% higher rate of lung cancer primarily due to higher rates of smoking. During World War II and the Korean War, asbestos also played a role, and Agent Orange may have caused some problems during the Vietnam War.Lung cancer is the third most-common cancer in the UK (around 46,400 people were diagnosed with the disease in 2014), and it is the most common cause of cancer-related death (around 35,900 people...
