And as it now turns out this signal is dependent on stimulation from thyroid hormone. 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.
Benign pulmonary nodules are just thatâbenign. There is very little growth or change, if thereâs any at all. Cancerous pulmonary nodules, however, are known to grow relatively quicklyâusually doubling in size every four months but sometimes as fast as every 25 days.
