What is a liquid biopsy, and when might my care team use it instead of a tissue sample?
Doctors use several tests together to check for lung cancer. One kind of test is called a biopsy.
To check for lung cancer, your care team usually uses more than one kind of test together. They will ask about your symptoms, your medical history, and your family history, and do a physical exam. They may order imaging tests, such as a chest x-ray or CT scan, to look at your lungs. They may order lab tests on your blood and sputum, which is the mucus you cough up. A biopsy, a procedure that takes a small sample of lung tissue to study closely, is another test they may use. Your care team decides which combination of these tests fits your situation.
