A lung biopsy is done to: 1  Diagnose certain lung conditions, such as sarcoidosis or pulmonary fibrosis. 2  In rare cases, a lung biopsy may be done for severe pneumonia, especially if the diagnosis is not clear. 3  Diagnose suspected lung cancer.
A lung PET scan is also used to stage lung cancer. Fast-growing tissues, such as lung cancer tumors, absorb more of the tracer substance than other tissues. These areas stand out on the PET scan. Your doctor can use the three-dimensional images to detect growing tumors. Cancer is assigned a stage between 1 and 4. Staging refers to how advanced a particular cancer is.
