Imaging of Lung Cancer: A Pictorial Review of TNM8

Abstract

Lung cancer continues to be a pervasive disease. It is the second most common cancer behind prostate cancer in men and breast cancer in women.1 There were an estimated 229,000 new cases of lung cancer diagnosed in the United States and an estimated 136,000 deaths from lung cancer in 2020.1 The high mortality of lung cancer is partly explained by its tendency to be asymptomatic in early stages, which makes it much more likely to be first diagnosed at more advanced stages when treatment options are much less effective.2 Once diagnosed, it is essential that the patient and physician quickly decide on the best treatment course.
