How is lung cancer staged? It is divided into four stages

Lung cancer can be divided into four stages, which are based on the severity of the patient's condition. Stage I lung cancer is milder, the tumor is smaller, and has not yet metastasized. It can be treated by surgical resection, and the patient's survival rate is relatively high. If lung cancer develops to stage IV, the cancer cells have metastasized to other parts of the body, such as the brain, bones, etc., and treatment is more difficult at this time, and the mortality rate is also higher.

Lung cancer is a malignant tumor that occurs in the lungs. It is clinically divided into stages one to four according to the severity of the disease, with stage four being the most serious. The staging of lung cancer determines the patient's chance of survival and also determines the formulation of treatment plans. Therefore, it is very important to understand the staging of lung cancer. So, how is lung cancer staged?
1. How is lung cancer staged ? Lung cancer can be divided into stages one to four. Stage one lung cancer is a mild disease. At this time, the tumor is small and has not metastasized. It can be completely removed by surgery. Stage two lung cancer includes two situations. One is that the tumor is small but has metastasized to the lymph nodes. The other is that the tumor is large but has not metastasized to the lymph nodes. Both situations belong to stage two lung cancer. When it comes to stage three lung cancer, the tumor has invaded the surrounding tissues. In this case, it is difficult to completely remove the tumor through surgery.
Stage IV lung cancer is the most serious. At this time, cancer cells can be transferred to other parts of the body through the blood, such as the brain, bones, liver, kidneys, etc., and cause symptoms in these metastatic sites. When it reaches stage IV lung cancer, which is what we call advanced lung cancer, the opportunity for surgical treatment has been lost and it can only be treated through radiotherapy, chemotherapy, etc.
2. How to treat lung cancer <br/>Early stage lung cancer is mainly treated with surgery. Before surgery, a detailed examination will be conducted on the patient. If the patient is in good physical condition and the cancer cells have not metastasized, the survival rate will be very high through surgical treatment. In the middle and late stages of lung cancer, it is necessary to determine whether surgery is needed based on the patient's specific situation. During this period, surgery can be combined with chemotherapy, radiotherapy and other methods for treatment. If the patient does not meet the surgical indications, chemotherapy or radiotherapy can also be selected.
At present, targeted drugs can be used for advanced lung cancer treatment, and it can also be combined with traditional Chinese medicine treatment to reduce the side effects of chemotherapy, radiotherapy and other treatments. Reasonable treatment of advanced lung cancer can prolong the patient's survival and improve their quality of life.
