Pulmonary nodule epidemiology and demographics
Introduction
Overview
Overview
Pulmonary nodules are common. The estimated prevalence of incidental pulmonary nodule ranges between 0.09% to 7% in the general population. The incidence rate of pulmonary nodule increases with age, tobacco use, and prior cancer; the median age at diagnosis is between 35 to 70 years. The prevalence of malignancy among pulmonary nodules ranges between 0.2% to 50%. Males are more commonly affected with pulmonary nodule than females. The male to female ratio is approximately 2 to 1. There is no racial predilection to pulmonary nodule.
