What does negative result mean regarding small lung nodules?

Too little info. What was "negative"? Did they biopsy it? Was it a pet scan, was it negative for serial growth on cxr? Ct scan? Negative is not descriptive enough. Give me more information and i will answer your concerns. Most nodules are not cancer.
Not malignant. A negative result by lung biopsy of a small lung nodule means it is not malignant. Other examinations of lung biopsies are performed to examine for evidence of infection or conditions which might cause lung nodules. A negative result of ct scan on followup exam means the nodules has remained the same or less in size. Lung nodules are followed for 2 years to be sure they do not increase in size.

Can small lung nodules be cancerous?

Rarely. In people without history of cancer, 5 mm or less in diameter lung nodules have a <1% chance of being malignant. Lung nodules are generally followed on ct scan for 2 years to be sure they do not grow in size. Those that grow can be biopsied by ct guidance, bronchoscopy, or surgery. Check for other causes (exposure to tb, rheumotologic). http://radiology.rsna.org/content/237/2/395.long. Read more...

What is a primary lung cancer that would cause multiple small lung nodules less than 5 mm when found?

Likely not lung canc. Multiple bilateral small lung nodules in someone of your age would more likely be from prior infections. If from cancer, they are more likely metastases from another cancer (eg, breast). If metastases from a primary lung cancer there would more likely be a dominant lung mass. Read more...

Bun 5, basophil auto1.2%, vit d is 24 and multiple small lung nodules could these all be connected and help with a diagnosis.

Lab data. Most of this is meaningless without knowing the clinical evaluation. There are multiple possible causes and this needs fully assessment by a physician. Good luck. Read more...
Not likely. Lung nodules require a careful history for prior exposure to agents like tuberculosis, industrial exposures like asbestos or tobacco. Follow-up imaging is needed. If size increases a pet ct and biopsy can be contemplated. Read more...

See your doctor. The nodules could be anything from scar tissue due to prior infections, rheumatoid nodules. To cancer. You should ask your doctor about these.

Lung nodules. Lung nodules are common. Especially in the midwest. Old imaging studies should be used to compare. If chronic -- ie they were there 10 years ago -- very likely benign. Also depends on size and other imaging characteristics. There are radiology guidelines for following lung nodules. Read more...

Father has multiple small lung nodules. Does not smoke. Had pneumonia several times and scarring from it on lungs 25 yrs ago. Is 70. Risk of cancer?

Possibly. This needs a systematic approach to diagnosis and may require some invasive procedures, depending upon what non-invasive studies reveal. It may take several visits to the doctor to have this all worked out. Could be very benign, but cancer must be excluded so that aggressive treatment can be started if it is present. Read more...
Possible. Histoplasmosis and granulomas more common in midwest. Comparison with old x-rays or ct is very helpful. New multiple lesions, and growth of lesions inclines to cancer. Read more...
