The Early Lung Cancer Action Project reported that the malignancy rate of GGNs (34%) was higher than that of solid nodules (7%) and that the malignancy rates of mixed GGNs (part-solid nodules) and pure GGNs (nonsolid nodules) were 64% and 18%, respectively.
The article doesn't say if they are found in the early stages of cancer but that finding them means that the there is a greater chance that there is cancer in the lung compared to other lesions.
Lung nodules do not have to be serious, but this depends on a number of factors. If you're under 40, a non smoker, and the nodule on X-Ray is found to have calcium in it, then it is unlikely due to be from cancer. If this is not the case, then it may be caused by cancer.
Nodules are hard to mine because they are found in very deep water
they are found growing the roots of plants e.g. cress
it is rhizobium
Chert is usually found in the form of nodules or lenses in bodies of limestones or dolomites.
In nodules on the roots.
oxides of manganese, nickel, copper and iron
Nitrogen
The nitrogen bacteria called RHIZOBIUM is found in the root nodules of leguminous plants.They are symbiotic.
iron, copper, nickel, or cobalt
In root nodules of lupins and other legumes.
