Lung cancer is staged by a TNM system, based on consideration of (1) the size, location, and extent of the primary tumor (T); (2) the presence or absence of lymph node metastases (N); and (3) the presence or absence of distant metastases (M). In some locations, nodes that contact vessels may be difficult to identify without contrast medium infusion. 90% of sarcoid patients will have an increased number of lymphocytes in their bronchoalveolar lavage fluid (21), giving it a rather high sensitivity.

Their function is to trap cancer and bacterial cells and ensure immunity in the pulmonary region. They're very common. The term is usually used to refer to lymphadenopathy or swollen lymph nodes.

However, no malignant cells were seen in the mediastinoscopy samples or the trans-bronchial biopsy samples. The relatively low specificity of bronchoalveolar lavage fluid makes it less useful than other tests in achieving a diagnosis. Fever (may come and go over several weeks) without an infection. A widened mediastinum is a feature often seen on a plain chest x-ray. For this reason, the diagnostic waters are muddied as some pathologies produce via reactive change the nodal enlargement and not because the pathology itself infiltrates the node.
