Lung metastasis

Lung metastases refer to malignant tumors that originate in other parts and metastasize to lung tissue through blood or lymph. Among the patients who died of malignant tumors, 20% ~ 30% had lung metastasis. The time of lung metastasis varies, and a few lung metastases are found earlier than primary tumors. Primary malignant tumors mostly come from breast, bone, digestive tract and urogenital system. Most pulmonary metastases are multiple lesions of both lungs, with different sizes and uniform density. At present, there is no effective treatment. Surgical treatment can be considered for a single metastatic lesion in the lung.
