What is a Lung Nodule?

Small masses of tissue known as lung nodules are not uncommon. Appearing as round, white shadows in an x-ray or CT scan, they are not usually cancerous. However, larger lung nodules, usually 25 mm or larger, are more likely to be cancerous than smaller ones.

If you have lung nodules, your doctor may compare new x-rays or CT scans with ones already on file to see if they have grown, change shape or altered their appearance. If they have, your doctor may recommend further tests at the Florida Hospital Cancer Institute (FHCI) such as a PET scan or even a tissue biopsy to see if the nodules are cancerous.  To learn more about treatment for lung nodules, or to schedule an appointment, contact us now at Florida Hospital Cancer Institute.

Our multi-disciplinary team of pulmonologists, thoracic surgeons, gastroenterologists and interventional radiologists work closely together to evaluate indeterminate lung nodules that may have been detected during routine examinations.

If necessary, additional tests may be conducted, ranging from a bronchoscopy with or without EBUS, an endoscopic ultrasound, CT-guided lung biopsy or a surgical biopsy.

If the results come back positive, one of our Cancer Care Coordinators will get in contact with you to schedule an appointment with a cancer specialist at the Florida Hospital Cancer Institute.

Lung Nodule Symptoms

In most cases, there are no recognizable symptoms of lung nodules. If lung nodules are present, any symptoms would be associated with the condition that led to the development of the nodules. For example, if the condition is lung cancer, a patient may have a cough, or may cough up blood. In most instances, the patient is unaware of the presence of lung nodules until a chest X-ray or computed tomography scan (CT scan) is performed.

Causes of Lung Nodules

Lung nodules can either be benign (non-cancerous) or malignant (cancerous). In most cases, the main causes of non-cancerous lung nodules include clumps of inflammed tissue (called granulomas) and benign lung tumors (called hamartomas). The most common cause of cancerous lung nodules include lung cancer, or another form of cancer from regions of the body that have spread to the lungs. There are several cause categories of lung nodules, including infections, inflammation, benign tumors, and malignant tumors.
