Lung Cancer

1/8th inch lung nodule



in Nov, I had a chest x-ray which showed emphazema but nothing else. First of Jan another chest x-ray and ct scan showed a lung nodule about 1/8th inch in size. Because of how quickly this showed up and the size, what are the chances that it is cancer?


You cannot really estimate whether this is growing and how fast because the first study was a chest xray, which is not very accurate. To accurately assess growth, you need to use the same technique. For a very small lesion like this, it is probably reasonable to repeat the CT scan in a few months. If unchanged, then the interval for repeat CT chest can then be lengthened. It may be appropriate to be evaluated by a lung cancer expert, such as a pulmonologist or thoracic surgeon, who is familiar with the evaluation and surveillance of pulmonary nodules.
