Overview
The incidence rate of lung masses is approximately 58 per 100 000 individuals in the United States. The incidence of lung masses increases with age; the median age at diagnosis is between 25 to 70 years. Males are more commonly affected with lung masses than females. The male to female ratio is approximately 2 to 1. There is no racial predilection for lung masses.
Epidemiology and Demographics
The following is the epidemiology and demographics of lung mass:[1]
Incidence
- The incidence rate of malignant lung mass is approximately 58 per 100 000 individuals in the United States
- The incidence rate of lung mass increases with age, tobacco use, and prior cancer
Prevalence
- The prevalence of malignancy among lung mass ranges between 0.2% to 50%
Age
- The median age at diagnosis for malignant lung mass is between 55 to 70 years.
- The median age at diagnosis for benign lung mass is between 20 to 50 years.
Gender
- Males are more commonly affected with lung mass than females. The male to female ratio is approximately 2 to 1.
Ethnicity
- There is no racial predilection of lung mass
Case Mortality Rate
- Lung cancer is the leading cause of cancer related death worldwide.
- It has been estimated that lung cancer accounts for approximately 1.5 million deaths annually.
- Amongst men, lung is the most common site for cancer while it is the third most common site in females.
