Lung Nodules: Diagnosis & Treatment in Dallas and McKinney, TX

Understanding Lung Nodules

Lung nodules, also known as pulmonary nodules, are small, roundish growths or "spots" on the lung detected during chest X-rays or CT scans. These nodules are common—found in nearly 1 in 3 chest CT scans—and most are benign, often caused by old infections, inflammation, or scar tissue. However, a minority of lung nodules may represent early lung cancer, making their accurate evaluation critical.

Comprehensive Evaluation and Care for Pulmonary Nodules

A pulmonary nodule is typically less than 3 centimeters in diameter and is most often discovered incidentally during imaging performed for other reasons. Nodules may be solid, part-solid, or ground-glass opacity in appearance on CT imaging. While the majority of lung nodules are benign, certain features—such as larger size, irregular borders, or growth over time—may indicate a higher risk of malignancy and warrant further investigation.

At O2 Pulmonary & Sleep Group, the evaluation of lung nodules includes a detailed review of your imaging, assessment of risk factors (such as smoking history, age over 65, previous cancer, or occupational exposures), and personalized diagnostic plans. Our advanced diagnostic capabilities at our Dallas and McKinney clinics include:

• High-resolution CT scanning for detailed analysis of nodule size and characteristics
• Low-dose CT lung cancer screening for eligible patients
• Pulmonary function testing
• Bronchoscopy for visual inspection and biopsy of suspicious nodules
• Image-guided needle biopsy in coordination with local hospitals
• Active surveillance programs with periodic imaging for low-risk nodules

With offices in both Dallas and McKinney, Texas, O2 Pulmonary & Sleep Group is dedicated to bringing cutting-edge pulmonary care closer to the communities we serve.

Symptoms and Risks of Lung Nodules

Most lung nodules do not cause symptoms and are discovered on imaging rather than due to clinical problems. Rarely, if a nodule is large or located near airways, symptoms such as cough, chest pain, or shortness of breath may develop. Malignant nodules can be associated with weight loss or hemoptysis.

Essential risk factors for malignant lung nodules include:

• Current or former smoker
• Age over 65
• Personal or family history of cancer
• Prior chest radiation
• Exposure to asbestos, radon, or other carcinogens

Our providers work with you to assess your personal risk and develop a monitoring or treatment plan tailored to your specific needs.
