Are lung nodules serious?
Yes, lung nodules can be cancerous, though most lung nodules are noncancerous (benign). Lung nodules — small masses of tissue in the lung — are quite common. They appear as round, white shadows on achest X-ray
Chest X-rays can detect cancer, infection or air collecting in the space around a lung, which can cause the lung to collapse. They can also show chronic lung conditions, such as emphysema or cystic fibrosis, as well as complications related to these conditions. Heart-related lung problems.

About 40 percent of pulmonary nodules turn out to be cancerous. Half of all patients treated for a cancerous pulmonary nodule live at least five years past the diagnosis. But if the nodule is one centimeter across or smaller, survival after five years rises to 80 percent. That's why early detection is critical.What would cause a nodule on the lung?
The most common causes of lung nodules are inflamed tissue due to an infection or inflammation (called granulomas) or benign lung tumors (such as hamartomas).

For example, if a person has an infection, they may have a fever, a cough, and a general feeling of being unwell.How big does a lung nodule have to be for biopsy?
Nodules between 6 mm and 10 mm need to be carefully assessed. Nodules greater than 10 mm in diameter should be biopsied or removed due to the 80 percent probability that they are malignant. Nodules greater than 3 cm are referred to as lung masses.Do lung nodules cause symptoms?
What are the symptoms of lung nodules? Small lung nodules rarely cause symptoms. If the growth presses against the airway, you may cough, wheeze or struggle to catch your breath.
