What does "Pulmonary Nodules" mean?
Table of Contents
Pulmonary nodules are small, round growths in the lungs. They can be found during chest imaging tests like X-rays or CT scans. Most nodules are harmless, but some can be a sign of lung cancer, especially if they change over time.
Causes
Nodules can be caused by various factors, including:
- Infections
- Inflammation
- Scarring from previous lung injuries
- Tumors, which can be benign (non-cancerous) or malignant (cancerous)
Diagnosis
When a nodule is found, doctors often want to know more about it. They may order additional imaging tests or a biopsy, which involves taking a small sample of the tissue to check for cancer cells.
Risk Factors
Certain factors can increase the risk of having lung cancer associated with pulmonary nodules, such as:
- Smoking
- Exposure to harmful substances, like asbestos
- Family history of lung cancer
Monitoring
Doctors may recommend monitoring nodules over time. This involves regular imaging tests to see if the nodule changes in size or appearance. A change can provide important clues about whether it's harmless or requires further action.
Treatment
If a nodule is found to be cancerous, treatment options may include:
- Surgery to remove the nodule
- Chemotherapy
- Radiation therapy
It’s essential to follow up with medical professionals to ensure proper care and management of pulmonary nodules.
