Health history, imaging tests, laboratory tests, biopsies, and biomarker tests are among the steps and tests used to detect lung cancer.

Only a biopsy will provide a conclusive diagnosis of lung cancer, so a person cannot know for sure if he or she has lung cancer until the biopsy results come back. The development of masses in the lungs can be caused by a number of diseases, including cancer. Imaging tests can be used to assess the location of possible cancer and whether it has spread, but they can never be used to make a diagnosis on their own.

If diagnosed with lung cancer, getting a second opinion may be an essential and necessary component of treating your diagnosis.  Click here to learn more about "Getting Second Opinion"
