You might have this small operation to check for signs of pleural mesothelioma. To do this your specialist doctor uses a flexible tube with a light and video camera attached. This is called a thoracoscope and is used to take samples (biopsies) from the tissues that cover your lung (pleura).
Why you might have it
This is often the only certain way of finding out what's wrong, because mesothelioma can be difficult to diagnose. Other tests might not show whether the problem is mesothelioma or a different type of lung problem.
You might have this small operation under a general anaesthetic, or with a local anaesthetic and a medicine to make you drowsy (sedation).
Your doctor makes a small cut (incision) in the inside of your chest between 2 ribs. Then they put a flexible tube with a light and video camera attached (thoracoscope) into the hole. They might use a CT scan or ultrasound scan to position the thoracoscope accurately.
Using forceps, the doctor takes a small sample (biopsy) of the tissues that cover the lungs (the pleura). They usually take a sample from the outer layer of the pleura. This is called the parietal layer.
The sample is then sent to a laboratory for testing to see if there are any cancer cells.
After the test
You might feel some pain, so you are offered painkillers. Do tell the doctor if you have any pain afterwards, or if you have breathing problems or feel unwell.
Getting your results
You should get your results within 1 or 2 weeks. The doctor may be able to let you know if they have seen any abnormal areas that have been sent to the laboratory.
Waiting for results can make you anxious. Ask your doctor or nurse how long it will take to get them.
Contact the doctor who arranged the test if you haven’t heard anything after a couple of weeks.
You might have contact details for a specialist nurse and you can contact them for information if you need to. It can help to talk to a close friend or relative about how you feel.
