Lung cancer
You usually start by seeing your GP if you have symptoms that could be due to lung cancer. They will ask you about your general health and may also examine you. Your doctor will then decide whether to do tests or refer you to a specialist.
Or you might be referred to a specialist and for further tests if screening for lung cancer or a lung health check showed that you might have lung cancer.
See your GP if you notice a change that isn't normal for you or if you have any of the possible signs and symptoms of lung cancer.
Your GP should arrange for you to see a specialist or have tests if you have symptoms that could be due to lung cancer.
In the UK, the National Screening Committee recommends that people at high risk of lung cancer are invited to screening. This is called targeted lung cancer screening.
Your GP or specialist might arrange for you to have tests. You usually have a chest x-ray, CT scan and PET-CT scan to diagnose lung cancer. You might also have a bronchoscopy and biopsy.
