What happens during a lung biopsy, and why is it needed along with imaging?
Doctors use more than one test to check for lung cancer. They start by asking about your health and family history. They also do a physical exam.
To check for lung cancer, your care team may use several tests together. They start by asking about your health history and family history. They also do a physical exam. They may order imaging tests, such as a chest x-ray or CT scan. They may also order lab tests, including tests of blood or sputum. A biopsy is often done too. A biopsy is a procedure that takes a small piece of lung tissue. Imaging, lab tests, and biopsy are all part of this same process.
Lung cancer may not cause any symptoms until it has become advanced. Sometimes lung cancer is found on a chest x-ray done for another reason.
If lung cancer is confirmed, more tests are done. These tests check whether the cancer has spread further. It may have spread to the lungs, lymph nodes, or other body parts. This step is called staging. Knowing the type and stage helps the care team plan treatment.
Your care team can explain what each test involves.
