what tests will I have?

Your GP will ask you questions about your symptoms and your lifestyle - for example, whether you have smoked, and what type of work you have done. S/he will look at your medical history to see what illnesses you have had.

S/he may then send you for a chest x-ray to get more information, or – depending on your symptoms – s/he may send you straight to see a specialist doctor at a nearby hospital. There are cancer referral guidelines to help GPs decide who needs to see a specialist, and how quickly.

Here are some of the tests you may have...

Chest x-ray
This lets your doctor see whether there is a shadow on the lung. If there is, the doctor will want to arrange some more tests to find out what it is.

Bronchoscopy
The doctor puts a thin, flexible instrument (a bronchoscope) through the nose or mouth and down into the lungs. S/he can then look for anything unusual, and take small samples of tissue (biopsies) to be examined under a microscope.

Mediastinoscopy
For the test, the doctor makes a small cut at the base of your neck, and passes a small viewing tube (mediastinoscope) through the cut, into the chest. A sample of tissue may be taken for examination under a microscope.

Lung biopsy
Sometimes a bronchoscope can't reach the suspected cancer. To get a sample of cells the doctor may need to put a very fine needle through the skin and into the lung. S/he can then draw up some cells into a syringe. You have a local anaesthetic first.

Computerised tomography (CT or CAT scan)
This is a type of x-ray that creates pictures of the inside of the body. You lie on a couch while it passes through a large hollow ring. Doctors use the scan to see whether the cancer has spread.

Blood test
A sample of blood will give the doctor information about your general state of health, for example how well your liver and kidneys are working.
