In the junction where the trachea meets the bronchi.-
The lung lymph nodes can be found along the bronchi. The paratracheal and tracheobronchial groups of lymph nodes are located in the neck and also in the junction where the trachea meets the bronchi, respectively. These accept drainage from the heart, lungs, bronchi, and thoracic trachea as well as other lymph nodes. Click to read more below. The mediastinal nodes are a group of lymph nodes located in the thoracic cavity of the body. These nodes play an important role in the filtration of lymph before it is returned to circulatory system. Anatomy The mediastinal lymph nodes are located in the region of the thoracic cavity between the lungs known as the mediastinum. There are two major groups of mediastinal lymph nodes: the anterior and posterior nodes. 1 Lymph nodes are important part of the immune system. 2  Lymph nodes are located throughout the body, but visible and palpable only when they are enlarged or swollen. 3  Lymph nodes are regional, and each group of them corresponds to a particular region of the body and reflects abnormalities in that region. Stages of Non-Small Cell Lung Cancer. Stage I: The cancer is located only in the lungs and has not spread to any lymph nodes. Stage II: The cancer is in the lung and nearby lymph nodes. Stage III: Cancer is found in the lung and in the lymph nodes in the middle of the chest, also described as locally advanced disease. Stage III has two subtypes: There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) . Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs.
