Why has lung cancer increased in women?

Lung cancer is the leading cause of cancer death among women in the United States. Over the past 50 years, the number of women who smoke cigarettes has increased significantly. This increase in smoking is the primary cause of the rise in lung cancer rates among women.

Other factors that may contribute to lung cancer in women include:

- secondhand smoke exposure

- occupational exposures to asbestos, silica, and other hazardous substances

- air pollution

- a family history of lung cancer

- certain medical conditions, such as chronic obstructive pulmonary disease (COPD) and asthma

It is important to note that lung cancer is largely preventable. Quitting smoking is the single most important thing that women can do to reduce their risk of lung cancer. Other measures that can help to reduce the risk of lung cancer include avoiding secondhand smoke, reducing exposure to air pollution, and eating a healthy diet that includes plenty of fruits and vegetables.
