Lung cancer transfer way | treatments for lung cancer
??Lung cancer growth rate and diffusion and transfer to the histologic type in cancer cells and differentiation degree and the patient?s immune function condition.Generally have the following several kinds of ways.
??
??(a) local spread directly
??
??After the occurrence of cancer in the bronchial wall to the bronchial lumen, led to growth in luminal stenosis or completely blocked.The cancer to bronchial foreign minister big namely into the lung tissue expansion, then spread against and adjacent organs.Central lung cancer spread expansion into the lung, mediastinum, door can oppression or violate lymphatic, blood vessels, nerves and is located in the mediastinum DuoZhong organs and tissues.Near the edge of the lung parts of the peripheral lung cancer is often protruded into pleural, cause pleural cavity effusion and chest wall transfer.The cancer can be through the crack between the lobes into the adjacent other lobe.Huge c?ancer because central part of tissue, liquefaction, ischemia, forming a cancerous empty.
??
??(2) lymphatic metastasize
??
??Lymphatic metastasize bronchus lung cancer is a common way to the main diffusion.Undifferentiated small cell carcinoma in early stage can metastasize via the lymphatic, squamous cell carcinoma metastasize via the lymphatic is more see.Adenocarcinoma blood often metastasize, but may also occur in the lymph metastasize.The bronchial lung cancer cells and blood vessels of the pipe into the surrounding lymph first adjacent lung paragraph or the lymph nodes, to varying degrees, bronchial lung cancer and then according to their positions to lung door, tracheal subcarinal lymph nodes, mediastinum, the trachea, again involving the supraclavicular, the anterior scalene and cervical lymph node.The mediastinal tracheal and cervical lymph node metastases, commonly occur in lung cancer with side, left lung cancer lymph node metastases may occur in the lung cancer to side, the so-called crossover transfer.Lung cancer into the chest wall and diaphragmatic surface after the pleural, lymphatic metastasize to the alar, the neck and upper abdomen lymph nodes.
??
??(3) metastasize blood
??
??The blood in lung cancer metastasize lesions has entered the late.Anaplastic carcinoma can present metastasize earlier blood.Adenocarcinoma metastasize blood is more see.Late squamous cell carcinoma metastasize also not see blood.Usually the cancer cells into the system, and then the left (with heart blood flow and systemic transfer throughout the body organs and tissues, the most common transfer parts have the liver, bones, adrenal, kidney, and brain.
??
??(4) the airway spread
??
??A few cases of cancer cells can fall off lung cancer by tracheal spread on the same side of the implant or other lung period to varying degrees, forming a new cancer or kitchen.The bronchioloalveolar carcinoma is often occur airway spread.
