11Upper Body Swelling
Swelling in the upper body is related to the superior vena cava, which is a major vein in the human body that carries blood from the head, neck, upper chest, and arms to your heart. As the tumor in the lungs keeps getting larger, it compresses the vena cava.
This compression leads to the Superior Vena Cava Syndrome, a direct result of which is swelling in the areas to which the vein carries blood – head, neck, upper chest, and arms. This swelling in the upper body could also be accompanied by trouble in breathing or shortness of breath and even coughing.
