Lung metastasis is a common mode of metastasis for advanced malignant tumors. Metastases in both lungs suggest distant metastases from advanced primary malignant tumors, indicating that the primary tumor is in an advanced stage. When this situation occurs, the tumor patient has a large tumor load in the body and a shorter expected survival.
In this case, targeted chemotherapy and other treatments can be selected according to the primary tumor site, and surgery is not recommended. In addition, we should also actively improve the examination to exclude the existence of metastasis in other organs of the body. Thus, it can provide the basis for the comprehensive evaluation of the patient’s primary tumor.
Thus, double lung metastases are malignant tumors, suggesting advanced tumor stage.
