What are the stages of small cell lung cancer? These need attention

There are two commonly used small cell lung cancer staging methods in hospitals. The first is to use international standards and the TNM method for diagnosis and treatment. In addition, the limited stage and extensive stage methods can be used to distinguish them, and appropriate treatment methods can be selected for diagnosis and treatment. In addition, in order to avoid the occurrence of small cell lung cancer, it is necessary to reduce smoking and choose appropriate methods for treatment after chronic infection occurs in the lungs.

Each type of cancer has its own stages. The earlier the disease is treated, the better the treatment effect will be, and the cancer can be better prevented from getting worse. Small cell lung cancer also has specific stages, and different symptoms will appear during different stages of the disease. So what are the stages of small cell lung cancer?
1. What are the stages of small cell lung cancer ?<br/>Currently, small cell lung cancer is still staged according to international standards. The international staging of small cell lung cancer adopts the TNM model. T stands for developing tumor, N stands for regional lymph nodes, and M stands for distant metastasis. According to these three different stages, small cell lung cancer can be divided from stage 1 to stage 4.
In addition to this staging, there is another staging method for small cell lung cancer, which is to divide small cell lung cancer into limited stage and extensive stage. This method of staging is to facilitate treatment, and appropriate treatment methods can be selected according to different situations.
Since small cell lung cancer is more sensitive to radiotherapy, it is in the limited stage at this time. If there is no good effect after radiotherapy, the next step of radiotherapy cannot be carried out, which is called the extensive stage. This stage will be more general, but it has a certain guiding role in the treatment of small cell lung cancer.
2. What causes small cell lung cancer?
1. Smoking <br/>Continuous smoking and long-term inhalation of excessive dust will cause cancerous lesions in the bronchial epithelium. In addition, cigarettes contain a large amount of carcinogens, which will invade the lungs and cause cancer.
2. Chronic lung infection <br/>If there are primary tuberculosis, bronchiectasis and other diseases, it will easily lead to squamous epithelium in the bronchial epithelium, leading to cancer. Therefore, after the occurrence of chronic lung diseases, do not take it lightly, and timely treatment is needed to reduce the possibility of cancer.
3. Air pollution <br/>Air pollution can also cause many people to develop small cell lung cancer. Especially in industrially developed areas, the poor air quality can easily lead to the occurrence of small cell lung cancer.
