One of the most well-known symptoms of lung cancer is a persistent cough.
However, coughs can be a symptom of many other conditions, so how can you distinguish a regular cough from one that could be a symptom of lung cancer?
The NHS said if your cough doesn’t go away after two or three weeks, to come and get it checked out.
It also warns a cough you’ve had for a while which keeps getting worse could be cause for concern, as well as coughing up blood.
