Understanding Lung Cancer

A chest X-ray will often show a lung tumor.
CT scans and PET scans are often used to provide more detailed information.
To be certain if you have lung cancer, tissue from your lung will be removed to look for cancer cells. This is called a biopsy.
The biopsy may be done during a bronchoscopy. During this test, a flexible tube with a light is inserted into your nose or mouth to look at the airways of the lungs.
A biopsy may also be done with a thin needle inserted through the skin directly into the tumor.
