Patients with lung cancer have more serious swelling in the face, which may invade or compress the surrounding blood vessels. Swelling of face in lung cancer may be caused by tumor compressing superior vena cava, hypoproteinemia or renal dysfunction.
Superior vena cava is closer to lungs, so lung tumor is easy to compress superior vena cava, while superior vena cava mainly returns blood to head and neck, when tumor compresses superior vena cava, it leads to blood stagnation in head and face, which causes increased hydrostatic pressure in blood vessels to appear face swelling.
Once the face is swollen, it is necessary to go to the hospital to do chest CT for examination and timely find out the cause of the disease. In the early stage, surgery can be taken to remove the tumor, but in the middle stage and the late stage, the disease will spread, and usually surgery cannot be taken, only radiotherapy and chemotherapy can be taken to prolong the patient’s life and improve the quality of life.
