Lung cancer symptoms: Changes in your cough could be one of the signs of the disease
Lung cancer affects around 44,500 people in the UK every year.
In many cases, symptoms usually only occur when the cancer has become too advanced to cure.
Like many other cancers, lung cancer can be detected at the earliest stage (stage 1) so it is important to recognise all the symptoms.
Cancer Research UK says a cough that will not go away can be a tell-tale sign of the disease.
