Lung cancer is one of the most common and serious types of cancer.
Around 47,000 people are diagnosed with the condition every year in the UK.
There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including:
- a persistent cough
- coughing up blood
- persistent breathlessness
- unexplained tiredness and weight loss
- an ache or pain when breathing or coughing
You should see a GP if you have these symptoms.
Types of lung cancer
There are two main forms of primary lung cancer.
These are classified by the type of cells in which the cancer starts growing.
- Non-small-cell lung cancer. The most common form, accounting for more than 87 per cent of cases.
- It can be one of three types: squamous cell carcinoma, adenocarcinoma or large-cell carcinoma.
- Small-cell lung cancer – a less common form that usually spreads faster than non-small-cell lung cancer.
