What is a noncalcified pulmonary nodule?

Answers:    A pulmonary nodule is a small, roundish growth on the lung—sometimes called a spot on the lung—that is easy to find and hard to diagnose. Pulmonary nodules turn up within about one of every 500 chest x-rays. But because they can be a form of early-stage cancer, it’s important to distinguish a benign nodule from a cancerous nodule as early as possible. Therefore, doctors approach every pulmonary nodule as cancerous until they can prove otherwise.
istinguish a cancerous nodule from a benign nodule is to evaluate its calcification—that is, its nouns based on its shape and surface. Benign nodules tend to be smoother and more regularly shaped, with more even color throughout. Cancerous nodules are more likely to enjoy irregular shapes, rougher surfaces, and color variations or speckled patterns.
