Patients suffering from malignant tumors will face a very difficult problem, that is, diffusion and metastasis. This is why it is difficult to cure the tumor. Early tumors generally do not have the problem of metastasis, but breast cancer is an exception, breast cancer is prone to axillary lymph nodes or other parts of the transfer, the lung is also the site of frequent metastasis.
Breast cancer often occurs in various parts of the body, which is the most common site of lung metastasis. Lung metastasis of breast cancer is mainly due to the formation of blood circulation. Cancer cells enter the blood stream with the breast vein, flow through the lungs, stay in the pulmonary capillaries and grow, and then penetrate the wall of the blood vessels, into the lung tissue to form lung cancer metastasis. Because the metastatic cancer does not directly invade the airway epithelium, the clinical manifestations are often different from those of primary lung cancer. Most of the patients only in the conventional X-ray chest film examination, only to find in the lungs with multiple size of the nodules of different types of lesions, lesions in both lungs and more common. In the clinical exclusion of other infectious diseases, combined with the primary breast cancer can be diagnosed.
Advanced breast cancer lung metastasis often invade pleura, can cause chest pain and pleural effusion; invasion of lung bronchus, can cause cough or sputum with blood and other symptoms; invasion of hilar or mediastinal lymph nodes, can have difficulty breathing, eating barrier and compression symptoms; cancer a few patients recurrent laryngeal nerve compression a hoarse voice. Some cases had carcinomatous lymphangitis, clinically manifested as cough, shortness of breath, obvious cyanosis, early X-ray no abnormality or only increased lung markings, should be differentiated from interstitial pneumonia, to avoid misdiagnosis. Can also be a PET-CT to identify. One
