Non-small cell lung cancer and small cell lung cancer have similar symptoms. Early signs and symptoms include cough that persists or worsens, coughing up blood or phlegm, chest pain that gets worse when you laugh, cough, or breathe deeply, hoarseness, trouble in breathing, wheezing, weakness and exhaustion, appetite loss and weight loss. Recurrent respiratory infections, such as pneumonia or bronchitis, are also possible.
Additional symptoms vary depending on where new tumours originate as cancer spreads.
- Lumpy lymph nodes, especially in the neck or collarbone.
- Bone discomfort, especially in the back, ribs, and hips.
- Headache, dizziness, balance problems, or numbness in the arms or legs are all symptoms of a problem with the brain or spine.
- Yellowing of the skin and eyes is a symptom of liver disease (jaundice).
Face nerves can be affected by tumours on the top of the lungs, resulting in drooping of one eyelid, tiny pupils, or a lack of perspiration on one side of the face. Horner syndrome is the name given to these symptoms when they occur together. Shoulder pain is also a possibility. Tumours can obstruct the major vein that carries blood from the head to the arms and heart. The face, neck, upper chest, and arms may enlarge as a result of this.
Lung cancer can produce a chemical that mimics hormones, resulting in a wide range of symptoms known as paraneoplastic syndrome, which include: muscle wasting, vomiting, nausea, retention of fluid, elevated blood sugar levels, high blood pressure, coma, confusion and seizures.
