CT Lung Cancer - Video Lesson

Everybody, welcome back. In this lesson we're discussing lung cancer. Lung cancers fit into two general categories. Bronchogenic carcinoma is the term we use to describe primary lung cancers. This includes adenocarcinoma, squamous cell carcinoma, large cell carcinoma, and small cell carcinoma. As technologists, it is not especially important for us to distinguish between each subtype, but we should recognize these terms when we see them. Those four cancers are the histological subtypes of bronchogenic carcinoma that is primary lung cancer. The other type of lung cancer, is much more common, is pulmonary metastases. We'll discuss both categories of lung cancer beginning with bronchogenic carcinoma. Bronchogenic carcinoma refers to any primary malignancy of the lungs, including the four histological subtypes adenocarcinoma, squamous cell carcinoma, large cell carcinoma, and small cell carcinoma.
