1 Pulmonary nodules appear in about one of every 200 chest X-rays and most chest CT scans. 2  At least 60% of pulmonary nodules seen on chest X-rays turn out to be benign, and 99% of those on chest CT are benign. 3  Pulmonary nodules are much more commonly found than are lung cancers or benign lung tumors. A way to tell the difference between a benign and malignant lung nodule is to chart the rate of growth of the nodule. 2  Benign nodules will grow very slowly, if at all, while cancerous nodules on average can double in size every four months or less.
A nodule is a spot on the lung, seen on an X-ray or computed tomography (CT) scan. In fact, a nodule shows up on about one in every 500 chest X-rays. Normal lung tissue surrounds this small round or oval solid overgrowth of tissue. It may be a single or solitary pulmonary nodule. Or, you may have multiple nodules.Your lung nodule is more likely to be benign if: 1  You are younger than age 40. 2  You are a nonsmoker. 3  There is calcium in the nodule. 4  The nodule is small.he first thing that may come to mind is a dreaded word: cancer. In many cases, though, a lung nodule turns out to be benign. This means that it isn't cancer. A hard part is waiting and not knowing.
