Lung cancer is a malignant tumour which grows in the tissues of the lung. It is the third most common cancer in the UK with an estimated life time risk of developing lung cancer being 7% for females and 8% for males.
Lung cancer is more commonly diagnosed in people aged 75 and over and is often diagnosed late with 46.1% of new lung cancers in England being stage 4 at diagnosis in 2018.
While over 90% of patients are symptomatic at presentation, symptoms can be vague and similar to other conditions more common in primary care.
This guideline is aimed at primary care clinicians to provide guidance regarding when to suspect lung cancer, what investigations to perform and when to make a referral to the urgent suspected lung cancer clinic.
