Normally, people with early lung cancer do not show any of the symptoms. However, when the disease spreads, the following symptoms may be experienced.
- Chronic cough (dry or productive cough)
- Breathing problems, such as the shortness of breath
- Chest pain
- Frequent lung infections, such as pneumonia
- Weakness or fatigue
- Unexplained weight loss
All of these symptoms are not always related to lung cancer as there are many diseases that present in the same way. If you do experience these symptoms, you should see your doctor as soon as possible.
