Decrease in lung cancer deaths in women

Lung cancer is the leading cause of cancer death among women1, and the second-leading cause of death after heart disease.2,3 But the good news is that lung cancer deaths in women continue to decline each year4, thanks in part to federal programs to help women quit smoking and federally funded research leading to improved treatments, scientific understanding, and public health policies.5,6

Smoking is the leading risk factor for lung cancer, yet 1 in 5 women diagnosed with lung cancer have never smoked. Women are more likely than men to develop non-small cell lung cancer (NSCLC), a type of lung cancer that is most commonly found in non-smokers.7 The hormone estrogen may play a role. A 2009 report from the Women's Health Initiative found that hormone therapy increased the risk of dying from lung cancer in post-menopausal women.8 However, women of all ages are more likely to survive longer with lung cancer than men.9 Women who have surgery for certain types of lung cancer, including NSCLC, also have better survival rates than men.10 They also respond better to some of the chemotherapy medications used for lung cancer.11

Lung cancer death rates in women decreased each year from 2004 to 2010 because of advances in treatments and successful smoking cessation programs.12 The U.S. Preventive Services Task Force has recently recommended lung cancer screening for high risk individuals.13 This may allow for the identification of lung cancer in its early stages when it is most treatable.
