Topics[edit]

Squamous Cell Carcinoma (SCC) of the Lung[edit]

Also known as epidermoid carcinoma, SCC is a type non-small cell lung cancer.

Bronchoalveolar Carcinoma (BAC)[edit]

BAC is a type of non-small cell lung cancer. It occurs predominantly in two types: mucinous and non-mucinous.

Metastatic Breast Cancer (MBC) of the Lung[edit]

Metastatic Hepatocellular Carcinoma (MHC) of the Lung[edit]

Terms[edit]

Lepidic growth pattern
a single layer of pulmonary adenocarcinoma cells may spread along the expanse of alveolar surfaces without invading alveolar septal stroma in a pattern of growth that has come to be referred to as lepidic because of its vague resemblance in cross-section to a butterfly. Furthermore, this process is commonly multifocal. Enlarged and poorly functional malignant alveolar cells may block gas exchange and cause respiratory failure and death without destroying underlying lung tissue.
Emphysema
a chronic respiratory disease where there is over-inflation of the air sacs (alveoli) in the lungs, causing a decrease in lung function, and often, breathlessness.
