What are the symptoms of a solitary pulmonary nodule (SPN)?

ANSWER

Most persons with a SPN do not experience symptoms. Generally, a SPN is detected as an incidental finding.

Lung cancer can often appear as an SPN on chest X-ray. Therefore, the goal of investigating an SPN is to differentiate a benign growth from a malignant growth as soon and as accurately as possible.
