33 NCCN Guidelines for Patients ® : Lung Cancer – Non-Small Cell, 2018 bronchoscope that is fitted with a second open channel that is thinner and longer. For this test, your doctor will first plan how to reach the cancer site using CT. Your doctor will then guide the bronchoscope to the site with a sensor that will be inserted through an open channel. When the site is in reach, the sensor will be removed and the sampling tool will be inserted.  Lung function tests Surgery and radiation therapy are treatment options for stage I and II, and some stage III and IV tumors. To assess if you can have these treatments, your doctors will need to know how well your lungs work. There are three lung tests that are called pulmonary function tests. A common side effect of these tests is shortness of breath. † † Spirometry involves blowing into a tube to measure how much air and how fast you breathe. See Figure 10 . † † A gas diffusion test involves breathing in a harmless gas and measuring how much you breathe out. It tells how much oxygen travels from your lungs into your blood. † † Body plethysmograph involves sitting in a small room and breathing into a tube. This test measures how much air your lungs can hold and how much air is left in your lungs after you exhale. Biopsy Most people with lung cancer will have a biopsy of their lymph nodes or other sites. The clinical stage will be used to decide which sites to biopsy. Biopsy results may change the clinical stage. Biopsy by cancer stage The area between your two lungs is called the mediastinum. This area has lymph nodes. These nodes are more likely to have cancer when the lung tumor is larger and closer to this area. As such, a biopsy of mediastinal nodes may not be needed for 4 Treatment planning Lung function tests | Biopsy Figure 10 Spirometry Spirometry is a procedure that measures how well your lungs work. You may receive this test to assess if lung surgery and radiation therapy are treatment options.
