About PDQPhysician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.Purpose of This SummaryThis PDQ cancer information summary has current
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early,it may be easier to treat. By the time symptoms appear,cancer may have begun to spread. Scientists are trying to better understand which people are more likely to get certain types of cancer.

BackgroundIncidence and mortalityLung cancer has a tremendous impact on the health of the American public, with an estimated 228,190 new cases and 159,480 deaths predicted in 2013 in men and women combined. Lung cancer causes more deaths per year in the United States than the next four leading causes of cancer death combined. Lung cancer incidence and mortality rates increased markedly throughout most of the last century, first in men and then in women. The trends in lung cancer incidence and mortality rates have closely mirrored historical patterns of smoking prevalence, after accounting for an appropriate latency period. Because of historical differences in smoking prevalence between men and women, lung cancer rates in men have been consistently declining since 1990. The incidence rate in men declined from a high of 102.1 cases per 100,000 men in 1984 to 82.7 cases per 100,000 men in 2009. Consistent declines in women have not been seen.[1,2]
What is radon?Radon is a cancer - causing radioactive gas. It comes from the breakdown of uranium, which is a natural part of soil and rock. It is most commonly found in soil, water, building materials (such as granite or shale), and natural gas. Radon cannot be detected by human senses because it is odorless, tasteless, and invisible.How does radon exposure occur?In closed or poorly vented spaces
