Details of small cell lung cancer

Small cell lung cancer has a great impact on patients, and timely treatment is necessary for patients, otherwise it will seriously affect their normal life and put them under great pressure. They don’t know when they can be cured. So, let’s learn about the details of small cell lung cancer together!

It is generally believed that small cell lung cancer originates from Kulchitsky cells (argentophilic cells) in the bronchial mucosa or glandular epithelium and belongs to APUD (amine precursor uptake decarboxylation) tumor. Some people also believe that it originates from stem cells in the bronchial mucosal epithelium that can differentiate into neuroendocrine. Small cell lung cancer is the least differentiated and most malignant type of lung cancer. It often occurs in the central part of the lung, grows rapidly, and metastasizes early. Under a light microscope, the cancer cells are small and short spindle-shaped or lymphocyte-like, with little cytoplasm and a naked nucleus.

What are the symptoms:

1. Cough. Cough is a very common symptom in our daily life. Little do people know that early symptoms of lung cancer can also include cough. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

2. Low fever. Small cell lung cancer can also cause asthma and low fever. When the tumor blocks the bronchus, there is often obstructive pulmonary lobe. The degree varies. In mild cases, there is only low fever, and in severe cases, there is high fever. It can be temporarily improved after taking medicine, but it will relapse soon.

3. Chest pain Chest pain is also one of the main symptoms of small cell lung cancer. Early chest pain is mild, mainly manifested as dull pain, dull pain, uncertain location, and uncertain relationship with breathing. If the pain persists, it means that the cancer may involve the pleura.

4. Blood in sputum. The most serious symptom is blood in sputum, which makes patients panic. When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many patients seek medical treatment because of blood in sputum.

Because patients may have tumor metastasis to different parts of the body, it may also cause some symptoms. Family members must pay attention to observation and provide good care. For example, patients with bone metastasis often have abdominal metastasis, which often causes intestinal obstruction. At this time, you should pay attention to observe whether there are symptoms of abdominal distension and abdominal pain, and seek medical attention in time.
