Lung tumors depend specifically on the type, and different types of lung tumors are treated differently. For example, benign lung tumors that are relatively small do not require special treatment. If the tumor grows larger, surgery can be considered. If it is a malignant lung tumor, it also depends on the pathological stage. If early stage patients can be treated surgically, they are also mainly treated with radical surgery, and after surgery, they can be treated with radiotherapy, chemotherapy and other comprehensive treatments. However, for small cell lung cancer, it is easy to have metastasis in other locations, especially brain metastasis. Generally speaking, the effect of surgery is not too good, and patients are mainly treated by chemotherapy and radiotherapy. There is also a part of lung adenocarcinoma that can be considered to be treated with targeted drugs if there is a mutation in the patient’s genetic test, and the effect is also better.
