Nodule size and growth rate, along with shape and pattern of calcification, determine a nodule’s risk of being cancerous. Small nodules often don’t require treatment.
Lung nodules are spots or shadows that may show up in a chest X-ray. Learn what they are, symptoms, causes, if location matters and a size chart for cancer risk.
Learn about lung nodules and how thoracic surgeons and pulmonologists determine whether nodules are benign or cancerous.
Lung nodules are measured in millimeters (mm), and their size is a key factor in risk assessment: Small nodules are less than 10 mm in diameter. The majority of small nodules, especially those less than 6 mm, are benign.
Because some categories are stratified by low and high risk (e.g. for solitary solid pulmonary nodules <6 mm), clinicians are asked to assess the risk of malignancy using factors other than the nodule descriptors included in the guidelines (size, multiplicity, and attenuation).
Most lung nodules are benign, meaning not cancerous. Your doctor uses results from additional tests and your overall health and risk factors for lung diseases to determine the next step in treating your lung nodule(s). What are the signs that a lung nodule is cancer? Benign and cancerous lung nodules often look different on CT scan images.
A lung nodule is a small, round mass that appears as a white spot on an X-ray or CT scan. While most lung nodules are noncancerous (benign), they can still be concerning. Dr. Moghanaki explains what you need to know about lung nodules: When to worry about a lung nodule. Most lung nodules appear during unrelated imaging studies or lung cancer ...
