The performance of different types of lung cancer

Clinical manifestations of lung cancer There are many different types of cancer have different performance, such as squamous cell lung cancer, adenocarcinoma, small cell carcinoma, large cell carcinoma in terms of their clinical symptoms and performance characteristics of their own.
Squamous cell carcinoma is a common type of lung cancer, accounting for more than 40% of lung cancer, more older men, the vast majority of long-term smoking, squamous cell carcinoma found in the central-type lung cancer, often irritating intermittent cough or sputum history of blood or with fever, dyspnea history. Obstructive chest常呈performance leaves, segmental atelectasis pneumonia or the performance of fiberoptic bronchoscopy are often found in food patterns or partial obstruction of the new biological phenomenon of bronchial obstruction, and its surface often covered by white matter necrosis. It was peripheral squamous cell carcinoma can be demonstrated, patients often can be found in sputum squamous cell carcinoma. Compared to other types of squamous cell carcinoma and its slow growth, late shift.
Adenocarcinoma accounts for about 40% of lung cancer, second only to squamous cell carcinoma, but have increased in recent years the trend to women than men. Performance around the chest-type, most often solitary pulmonary nodule lesions appear, often in asymptomatic patients, or for a medical examination found that there was a slight chest pain. The types often easy to transfer to the pleura, or pericardium, or chest showed pericardial effusion. Blood Road is also the Book of Changes or lymphatic metastasis, easily transferred to the liver, brain, bone, adrenal gland and associated organs such as the symptoms.
Small cell carcinoma accounts for about 10% of lung cancer is the highest degree of malignancy of lung cancer in a patient is often the age of partial light to found the performance of central lung cancer and its hilar lesions occur in the vicinity of the main bronchus, easy to mucosal under infiltration, bronchial regular violations of the substance outside the lung, and easy to hilar and mediastinal lymph nodes fused into clumps, fiberoptic bronchoscopy bronchial mucosa also usually uneven, bureaucratic hyperemia, edema, stenosis was the performance of submucosal infiltration, the sick often irritating cough with phlegm or blood history. Small cell lung cancer as a result of value-added fast and strong attacks, almost all small cell lung cancer was found, there are hilar lymph node metastasis or liver, brain, bone, adrenal gland and other organs and to produce symptoms of metastasis.
Large cell lung cancer can be divided into giant cells and clear cell type. The less common type, accounting for 6% of lung cancer, mostly in peripheral, the majority of patients through the early stage of lymph node metastasis and blood, resulting in the transfer of parts of the corresponding symptoms.
Although the common pathological type of lung cancer for the above four, but often the incidence of lung cancer for a variety of types at the same time, should be clinically relevant to know more about the symptoms of various types, so an accurate diagnosis and treatment.
