Many studies have revealed symptoms of lung cancer that require the person to see a doctor immediately, including a blood cough, difficulty breathing, unexplained fatigue, weight loss, and pain when breathing or coughing. However, these studies have not revealed a suspicious appearance on the face that may be a symptom of this deadly disease.
The "Long Cancer" medical site confirms that lung cancer causes swelling of the face and neck, and this is evident when the tumor presses the vein that runs from head to heart, in what is known as obstruction of the superior vena cava, which transports blood from the head and arms to the heart.
The site says that this form of symptoms is often caused by cancer, such as lung cancer, breast cancer, lymph nodes, or testes, or thyroid cancer, and it can happen for a non-cancerous cause, such as lung infections.
These symptoms are accompanied by the appearance of dizziness, headache, visual disturbances, fainting, and redness of the face. Symptoms may gradually develop, forming swelling around the eye in the morning as soon as they wake up from sleep.
