A new study by Canadian researchers supports the theory that lung cancer may spread through the airways.
“Cumulative evidence suggests that intrapulmonary aerogenous spread may exist and is underrecognized,” say the authors of “Aerogenous Metastases: A Potential Game Changer in the Diagnosis and Management of Primary Lung Adenocarcinoma,” published in the December 2014 issue of the American Journal of Roentgenology. “Aerogenous metastases must be differentiated from multiple synchronous lesions in the spectrum of lung adenocarcinoma, [and] imaging features are helpful in differentiating possible aerogenous spread of tumor.”
