In a just-published study scientists now believe that anemia may be the first sign of hypothyroidism, an issue they also document for subclinical hypothyroidism. In the past I have always viewed anemia as a thyroid disrupter.
Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A classic solitary pulmonary nodule (SPN) is a single, spherical, well-circumscribed, radiographic opacity measuring less than or equal to 30 mm in diameter and is surrounded completely by aerated lung.
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.
