Massive hilar lymph nodes are first considered benign and malignant. Malignant tumors, acute and chronic inflammation can make lymph nodes swell.
For malignant tumors: lung cancer, lymphoma, pleural mesothelioma, and other tumor metastases can make the hilar lymph nodes swell;
For benign lesions: chronic inflammation of the lung (tuberculosis, branched expansion, etc.), acute and chronic lymphadenitis can make the hilar lymph nodes swell. Therefore, it is necessary to visit a specialized department in the hospital to diagnose and treat the condition through consultation and examination.
