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.

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.
In radiology, a solitary pulmonary nodule (SPN) or coin lesion is a mass in the lung smaller than 3 centimeters in diameter.It can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans.he nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way.
