Pre death symptoms of poorly differentiated lung adenocarcinoma?

summary

It is very difficult for patients to find low differentiated lung cancer in the early stage, because the symptoms are not very obvious in the early stage. If our patients do not pay attention to their physical condition, it is difficult to find the existence of low differentiated lung cancer. In the middle and late stage, the symptoms of poorly differentiated lung cancer will appear. At this time, the disease will bring great harm and influence to our patients' body, and the difficulty of treatment will also increase greatly. Therefore, we must treat poorly differentiated lung cancer as soon as possible. So, what are the pre death symptoms of poorly differentiated lung adenocarcinoma? Now we are aiming at this problem to carry on the simple understanding and the understanding!

Pre death symptoms of poorly differentiated lung adenocarcinoma?

1. Cough is the most common symptom, with cough as the first symptom accounting for 35% - 75%. Cough caused by lung cancer may be related to changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion, atelectasis and other chest complications. When the tumor grows in the bronchial mucosa above the large diameter and sensitive to external stimulation, it can produce cough similar to that caused by foreign body like stimulation. The typical manifestation is paroxysmal irritative dry cough, which is often difficult to control by general antitussive drugs. When the tumor grew in the small bronchial mucosa below the segment, the cough was not obvious, or even no cough. For patients with smoking or chronic bronchitis, such as the degree of cough aggravating, frequency conversion, cough nature changing, such as high pitched metal tone, especially in the elderly, we should pay close attention to the possibility of lung cancer.

2. Blood in sputum or hemoptysis is also a common symptom of lung cancer, which accounts for about 30% of the initial symptoms. Due to the rich blood supply and brittle texture of tumor tissue, blood vessels rupture during severe cough, which may also be caused by local necrosis of tumor or vasculitis. Hemoptysis of lung cancer is characterized by intermittent or persistent, repeated small amount of blood in sputum, or a small amount of hemoptysis. Occasionally, it is difficult to control massive hemoptysis due to rupture of large blood vessels, formation of large cavities or tumor breaking into bronchi and pulmonary vessels.

3. The first symptom of chest pain was chest pain in 25%. Often for chest irregular dull pain or dull pain. In most cases, peripheral lung cancer invades parietal pleura or chest wall, which can cause sharp and intermittent pleural pain. If it continues to develop, it will evolve into constant drilling pain. Mild chest discomfort, which is difficult to locate, is sometimes associated with mediastinal invasion of central lung cancer or involvement of blood vessels and peripheral nerves. 25% of patients with malignant pleural effusion complained of blunt chest pain. Persistent acute chest pain, which is difficult to control by drugs, often indicates extensive pleural or chest wall invasion. Persistent pain in the shoulder or chest and back suggests the possibility of tumor invasion near mediastinum.

matters needing attention

1. the study of smoking control and smoking has proved that smoking cessation can significantly reduce the incidence of lung cancer, and the earlier the time is, the more obvious the lung cancer incidence rate decreases. Therefore, smoking cessation is the most effective way to prevent lung cancer. 2. protect the environment protect the environment has already proved that air pollution, sedimentation index, smoke index, benzopyrene and other exposure dose and lung cancer incidence rate is positively correlated, protecting the environment and reducing air pollution is an important measure to reduce the incidence of lung cancer. 3. occupation occupation prevention occupation cancer causing many lung cancer incidence rate has been recognized, reduce occupational exposure to carcinogens can reduce the incidence rate of lung cancer. 4. Scientific diet can prevent lung cancer by increasing vegetables and fruits in diet. Pulmonary infection is sometimes difficult to differentiate from obstructive pneumonia caused by bronchial obstruction of lung cancer. However, if pneumonia occurs in the same location for many times, we should be alert. We should highly suspect that it is caused by tumor blockage. We should take the patient's sputum for cytological examination and fiberoptic duct examination. In some cases, the inflammation of the lung is partially absorbed, and the remaining inflammation is wrapped by fibrous tissue to form nodules or inflammatory pseudotumor, which is difficult to differentiate from peripheral lung cancer, Thoracotomy should be performed in suspicious cases.
