Tests after diagnosis – staging lung cancer
Grading describes the cancer cells – what they look like and how they might grow. This is examined on your biopsy (tissue sample).
Staging describes where the cancer is in your body and how big it is.
You may have more tests after your diagnosis to find out:
- How large is the cancer?
- Where exactly is the cancer?
- Has the cancer spread to any other parts of your body?
This is called staging. Some of these tests may also be done when diagnosing and to check your response to treatment.
For most lung cancers, doctors don't use a specific grading system, although they may give it a grade number from 1-4.
Staging tests for lung cancer include:
A type of bronchoscopy that uses an ultrasound probe to look at the lungs and surrounding lymph nodes. Biopsy (tissue) samples from the lung or lymph nodes can be taken by passing a needle through the tube. This is called a transbronchial needle aspiration (TBNA).
Similar to an EBUS, but the probe goes down your oesophagus (gullet) to give images of the area around the heart and lungs, to show if any of the lymph nodes in the centre of the chest are enlarged.
A flexible tube with a light and camera put into your chest through a cut between your ribs. It can see if the membranes that line the lungs (pleura) look normal.
Lung function tests
Your doctor will organise a range of breathing tests to see how well your lungs are working. The main type of breathing test is a pulmonary function test. This is where you blow into a mouthpiece on a machine to see how well your lungs work. The test is not painful and takes about 20 minutes.
Staging tests are important as they help your medical team decide on the best treatment for your cancer.
