The symptoms of lung cancer may cause compression or invasion of the superior vena cava, resulting in superior vena cava syndrome, which is characterized by varicose veins in the face, neck, upper limbs and upper chest, subcutaneous tissue edema, and increased venous pressure in the upper limbs.

The symptoms of lung cancer may cause compression or invasion of the phrenic nerve, resulting in ipsilateral diaphragm paralysis, elevation of diaphragm position, disappearance of movement or abnormal movement, that is, the diaphragm rises when inhaled and falls when exhaled.
