Lung cancer is the growth of abnormal cells, originating within the lungs that increase in number to become a tumour (cancer). The following information is specific to cancers arising within the lung, and does not deal with cancer in the lung that has spread or originated from elsewhere.
In the UK 41,400 people each year are diagnosed with lung cancer. 9 out of 10 cancers are related to smoking, but other risks include increasing age, genetic risks, previous cancer treatment and asbestos exposure.
Symptoms include a persistent cough, phlegm with blood in it, breathlessness, chest pain, reduced appetite, fatigue, weight loss and hoarse voice. If concerned about the presence of any of these symptoms you should contact your GP.
