Are there lung nodules larger than 8 mm in diameter?
The cancer risk increases in pulmonary nodules larger than 8 mm. In the NELSON study the risk of malignancy in nodules larger than 10mm was 15.2% ( 34 ). Other radiological nodule features are spiculation, pleural indentation, nodule growth (Volume doubling time <400 days.) and upper lobe location ( 4 ).
How big is a pulmonary nodule at Cleveland Clinic?
Pulmonary nodules are smaller than three centimeters (around 1.2 inches) in diameter. If the growth is larger than that, it is called a pulmonary mass and is more likely to represent a cancer than a nodule. Cleveland Clinic is a non-profit academic medical center.

How often are lung nodules found on chest X-rays?
Countless pulmonary nodules are discovered each year during chest X-rays or CT scans. Most nodules are noncancerous (benign). A solitary pulmonary nodule is found on up to 0.2% of all chest X-rays films. Lung nodules can be found on up to half of all lung CT scans.

Lung nodules usually need to be at least one centimeter in size before they can be seen on a chest X-ray, whereas nodules as small as one to two millimeters may sometimes be seen on a CT scan. Prevalence
How big is a lymph node in lung cancer?
These lymph nodes are on the same side as the main lung tumor (N2). The cancer has not spread to distant parts of the body (M0). It is larger than 5 cm but not larger than 7 cm across.
