Can a complete blood count detect lung cancer?

As a medical professional with expertise in diagnostic testing, I can provide you with information on the capabilities of a complete blood count (CBC) in relation to lung cancer detection. A complete blood count (CBC) is a common blood test that provides important information about the types and amounts of cells in the blood. While it is a valuable tool for assessing a person's overall health, it is not typically used to diagnose lung cancer. The primary purpose of a CBC is to evaluate the body's ability to fight infections, detect anemia, and identify blood-related disorders. However, certain findings on a CBC, such as an elevated white blood cell count, could indicate the presence of an infection or other conditions, including cancer. It is important to note that a CBC is not specific enough to confirm a diagnosis of lung cancer on its own. If lung cancer is suspected, further diagnostic tests such as imaging studies (like CT scans), biopsies, or molecular testing would be required to confirm the diagnosis. In summary, a CBC can provide general health information and may raise suspicions of underlying health issues, including potentially cancer, but it is not a definitive test for lung cancer.

Blood tests are not used to diagnose lung cancer, but they can help to get a sense of a person's overall health. For example, they can be used to help tell if a person is healthy enough to have surgery. A complete blood count (CBC) determines whether your blood has normal numbers of different types of blood cells.
