Lung cancer is one of the most common types of cancer in the UK, affecting around 44,500 people.
Symptoms of this type of cancer develop as the condition progresses, and in the early stages, signs can be hard to detect.
Many of the symptoms of lung cancer could be mistaken for less common health conditions, like a persistent cough or loss of appetite.
Less common signs of the disease may surprise people, such as changes in the appearance of your fingers.
The NHS lists the main symptoms of lung cancer:
- A cough that doesn’t go away after two or three weeks
- A long-standing cough that gets worse
- Persistent chest infections
- An ache or pain when breathing or coughing
- Persistent breathlessness
- Persistent tiredness or lack of energy
- Loss of appetite or unexplained weight loss
Less common symptoms of the disease include finger clubbing.
Finger clubbing is when the ends of your fingers become more curved or appear larger.
Other less common symptoms of lung cancer include:
A high temperature (fever of 38C or above)
- Difficulty swallowing or pain when swallowing
- A hoarse voice
- Swelling of your face or neck
- Persistent chest or shoulder pain
If you experience any of the signs and symptoms you should visit your GP.
Another sign your cough could be linked to lung cancer is if you start coughing up blood. This may be small amounts of blood and you may cough up rust coloured phlegm.
Your sputum, another word for phlegm, could also have flecks of red in it.
It is more unusual to cough up larger amounts of blood, but you should see you GP straight away if this happens.
