Named a common symptom of lung cancer

A cough that does not go away for three weeks or longer may indicate the development of lung cancer.

This was reported by specialists from the National Health Service of Great Britain (NHS), reports BAKU.WS with reference to the Daily Mirror.

According to the NHS, in most cases a cough is caused by more typical reasons - a cold, flu, or COVID-19. However, if it does not go away or gets worse, this could be a warning sign. Among other possible symptoms, experts mention recurrent respiratory infections, coughing up blood, pain when breathing or coughing, persistent shortness of breath, fatigue, loss of appetite, and unexplained weight loss.

In addition, the service's website notes that less common signs of lung cancer include changes in finger shape, a hoarse voice, difficult or painful swallowing, wheezing, as well as swelling of the face or neck.

Medical professionals emphasize that smoking remains the main risk factor - it causes more than 70% of cases. Possible causes also include exposure to radon, asbestos, and coal fumes.
