A Lung Nodule is a small, round or oval-shaped growth in the lung that is easier to identify on a CT scan than on a standard X-ray. They are usually benign (noncancerous), but they can also represent the early stage of lung cancer.
Causes[edit]
Lung nodules can be caused by a variety of factors, including:
- Infection: Certain infections can cause lung nodules to form. These include tuberculosis and other bacterial, fungal, or viral infections.
- Inflammation: Inflammatory diseases such as rheumatoid arthritis and sarcoidosis can cause lung nodules.
- Cancer: Lung nodules can be an early sign of lung cancer. They can also be caused by cancer that has spread to the lungs from other parts of the body.
Diagnosis[edit]
The diagnosis of a lung nodule often involves a CT scan, which can provide detailed images of the lungs. Other diagnostic tests may include a PET scan, a biopsy, or a bronchoscopy.
Treatment[edit]
The treatment for a lung nodule depends on its cause. If the nodule is benign, no treatment may be necessary. If the nodule is cancerous, treatment options may include surgery, radiation therapy, or chemotherapy.
