As a medical professional with expertise in radiology, I can say that computed tomography (CT) scans are a valuable tool in the detection of lung cancer. CT scans create detailed images of the inside of the body, including the lungs, and can often identify abnormalities such as tumors or nodules that may indicate the presence of cancer. However, it's important to note that while CT scans can detect potential signs of cancer, they cannot definitively diagnose it.
Once an abnormality is detected, further tests are typically required to confirm whether it is cancerous. This may include a biopsy, where a small sample of tissue is taken from the suspicious area and examined under a microscope. Additionally, a CT scan is just one part of a comprehensive diagnostic process that may also involve other imaging studies, clinical examinations, and patient history.
It's also worth mentioning that while CT scans are useful, they are not without risks. They emit a certain amount of radiation, which, while generally considered safe for a single scan, can add up if multiple scans are performed over time. Therefore, they should be used judiciously and only when necessary.
In summary, CT scans are a crucial tool in the detection of lung cancer, but they are part of a broader diagnostic process and should be used in conjunction with other diagnostic methods.

When a low-dose CT scan of the chest is done for lung cancer screening, it's common to find small, abnormal areas (called nodules or masses) in the lungs, especially in current or former smokers. Most lung nodules seen on CT scans are not cancer. ... But tests are often needed to be sure a nodule is not cancer.
