If lung cancer is suspected in a patient, a series of different tests will be done to confirm the presence of disease (diagnosis), and to determine how widespread the disease has become (staging). You can get more information about reliable lung cancer genetic testing via online sources.
What X-rays, CT scans, and MRI scans?
Usually, patients are diagnosed with lung cancer when a doctor orders chest X-rays associated with other diseases. If lung cancer is detected by chest X-ray, CT (computer-assisted tomography) scan or MRI (magnetic resonance imaging) scan may also be ordered to confirm the diagnosis and staging of disease further.

CT scan and MRI scan test that uses computerized imaging to show in greater detail the size, shape, and the exact location of a suspected tumor. At the same time, the image will show whether cancer has spread to other parts of the body. If cancer has spread to other organs in the body, further tests will be ordered by a physician.
What is a lung biopsy?
A lung biopsy is where tissue is removed from the tumor and examined under a microscope to confirm whether cancer cells are present or not. This can be done through a needle inserted through the chest wall to take a sample of the tumor, or through surgery in which the chest wall is opened and either a part of the entire tumor is removed.
A lung biopsy is needed to determine an accurate diagnosis, and also to identify the specific type of lung cancer present in the patient.
