What is non-small cell lung cancer? It is a type of lung cancer

Non-small cell lung cancer is a type of lung cancer, and most lung cancer patients have non-small cell lung cancer. Non-small cell lung cancer is a disease caused by smoking, long-term exposure to chemicals, air pollution, or chronic lung infection. Patients with non-small cell lung cancer may experience chest pain, coughing up blood, fever, loss of appetite, weight loss, and difficulty breathing.

Non-small cell lung cancer is a malignant tumor with a relatively high mortality rate. When patients find themselves suffering from non-small cell lung cancer, they must actively seek treatment to prolong their lives. So, what is non-small cell lung cancer? Let's take a closer look at it!
1. Causes of non-small cell lung cancer <br/>There are many causes of non-small cell lung cancer, and smoking is the main cause. Since there are many chemical substances in cigarettes, ammonium nitrite and polycyclic aromatic hydrocarbon compounds are carcinogenic, and their carcinogenicity is very strong. If the patient's occupation requires long-term contact with some chemical substances, it will also cause non-small cell lung cancer. When a country's air pollution is more serious, it will also cause non-small cell lung cancer. There is also a relatively rare cause, such as some chronic infections in the patient's lungs, such as bronchiectasis, tuberculosis, etc., which are also prone to cause non-small cell lung cancer.
2. Symptoms of non-small cell lung cancer <br/>In the early stages of non-small cell lung cancer, patients will experience chest pain, which is a dull pain. If the chest pain persists, it means that the cancer cells have spread to the patient's pleura. When coughing, the patient will find a small amount of blood in his sputum, and will cough up blood intermittently. This is caused by cancer cells that damage the patient's capillaries. The patient will also have fever symptoms. If the patient's condition is relatively mild, it is a low-grade fever symptom. If the patient's condition is relatively serious, a high fever symptom will appear. And this fever symptom is recurrent.
In the late stage of non-small cell lung cancer, patients will experience symptoms such as loss of appetite, weight loss, general fatigue and lack of strength. There will also be local symptoms such as hemoptysis, coughing, and inability to breathe normally.
