The difference between benign and malignant lung tumors

Benign tumor and malignant tumor in lung are different. Benign tumor can show chest distress, cough and expectoration from clinical manifestation. Generally, he has no other systemic symptoms. The growth speed is relatively slow, mainly in expansion mode. CT of both lungs can show clear boundary of cancer species and regular morphology. Malignant tumors are easy to show obvious irritating cough, expectoration, hemoptysis and accompanied by systemic symptoms, manifested as weight loss, fatigue and persistent low fever, it is easy to show tumor metastasis. For example, brain metastasis outside the lung disease can show nausea, vomiting, headache symptoms, growth speed is relatively rapid, mainly in the form of invasive growth. CT of both lungs showed that the edges of the lesions were unclear, there were adhesions, and the shapes were irregular, such as burrs. Clinically, biopsy of the lesions could be taken for pathological examination, and cancer cells could be found in malignant tumors of the lungs.
