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.

Overview

The incidence rate of lung masses is approximately 58 per 100 000 individuals in the United States. The incidence of lung mass increases with age; the median age at diagnosis is between 25 to 70 years. Males are more commonly affected with lung mass 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][2]

Incidence

Prevalence

  • The prevalence of malignancy among lung mass ranges between 200-50,000 per 100,000 cases worldwide (or from 0.2% to 50%).
  • In 2014, there were an estimated 527,228 people living with lung cancer in the United States.

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.[3]

Ethnicity

  • There is no racial predilection of lung mass.

Case Mortality Rate

  • Lung cancer is the leading cause of cancer related death worldwide.[4]
  • From 2010-2014, the number of deaths from lung cancer was 44.7 per 100,000 men and women per year.[5]
  • 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.
