For the most part, lung nodules do not exhibit any symptoms, and are often found when performing chest X-rays for a different or unrelated medical reason. If symptoms do become present, they may include a persistent cough or coughing up blood.
The presence of lung nodules does not automatically signal cancer. Benign nodules can actually be quite common. To ensure that the nodules aren't cancerous, doctors at Florida Hospital will monitor changes in size, shape or appearance through regular tests.
