Depends on size: Many patients who undergo a ct scan of the chest will have small or medium size nodules that are non-specific. A radiologist will document the size, and depending on the patients age and risk factors for developing lung cancer will recommend appropriate followup studies or sometimes even recommend a biopsy. We can suspect, but not diagnose lung cancer without a tissue diagnosis. ...Read more

Is it possible to get lung cancer from a spiral CT scan?

Is it possible to get lung cancer from a spiral CT scan?

Possible Not Likely: Medical radiation is estimated to cause about 1% of cancers. Patients trested with radiation therapy have about a 0.5% chance of having a radiation related 2nd cancer. The risk from a single spiral ct is considerably less and would likely occur 10-20 years after the exposure. Bottom line is that tests like ct scans should only be ordered for good reasons. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
