Lung cancer screening is critically important because of the incidence and prevalence of lung cancer. More than 235,000 new cases of lung cancer are expected in the United States in 2021 with approximately 130,000 deaths expected in 2021. [1]
The consequences of overdiagnosis and overtreatment resulting from cancer screening can lead to a decline in quality of life, due to the adverse effects of unnecessary medication and hospitalization.

Lung surgery is a type of thoracic surgery involving the repair or removal of lung tissue, [1] and can be used to treat a variety of conditions ranging from lung cancer to pulmonary hypertension. Common operations include anatomic and nonanatomic resections, pleurodesis and lung transplants .
Several types of screening exist: universal screening involves screening of all individuals in a certain category (for example, all children of a certain age).
