Im looking for advice/reassurance. A recent ct scan shows 4 and 5 mm modules, one in lower lobe of each lung. I have a rescan in 4 months. What are the chances of these being lung cancer or metastases from elsewhere. Im very worried but I guess if its lung cancer it should be caught early.
1 Benign tumors â Benign lung tumors such as hamartomas can show up as a nodule in the lungs on x-ray. 2  Malignant tumors â This includes lung cancer, lymphomas, and cancer that has spread to the lungs from other parts of the body, among others. lung nodule is defined as a âspotâ on the lung that is 3 cm (about 1Â½ inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than 3 cm, it is considered a âlung massâ instead of a nodule.
