What happens at your GP appointment
When you contact your GP about lung cancer symptoms, your GP will ask about your general health and your symptoms.
They may examine you and ask you to breathe into a device called a spirometer. This measures how much air you breathe in and out.
They may ask you to have a blood test. This will help rule out some of the possible causes of your symptoms, such as a chest infection.
If your symptoms suggest you may have lung cancer your GP may:
- arrange for you to have a chest x-ray
- refer you to hospital or a rapid access lung clinic for tests
