Chest infections are commonly attributed to more innocuous health complaints, such as the common cold, but if your chest infection does not get better, or you experience repeated chest infections, it may signal lung cancer, warns Macmillan.

- Feeling breathless and wheezy for no reason
- Coughing up blood
- chest pain or shoulder pain that does not get better.
