Do lung nodules change in size?

Lung nodules are quite common, and most of them are benign, or noncancerous. Benign nodules don't require any treatment, but your physician will monitor any changes in size with follow-up scans. If the nodule appears to remain the same size, it is likely not cancerous.

What causes lung nodules to get bigger?

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). Less common, malignant lung nodules are typically caused by lung cancer or other cancers that have spread to the lungs (metastatic cancer).

Can a lung nodule shrink on its own?

Can you live a long life with lung nodules?

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 is considered rapid growth for a lung nodule?

Since few studies investigated the growth rate of pulmonary nodules, we defined the growth rate of pulmonary nodules according to previous studies. Most studies defined pulmonary nodules with a VDT >400 days and VDT ≤400 days as slow-growing and fast-growing pulmonary nodules, respectively (11, 19).

Can benign lung nodules change?
