Can a local tumor in the lung spread to develop bone metases without affecting the rest of the lungs on xr?

Yes. Small/oat cell carcinoma of the lung can disseminate widely in the body while the primary lesion may be too small to be detectable.
Yes, it can. This happened frequently especially in small cell lung cancer, but also in non small cell lung cancer . A "localized" tumor can spread and metastasize to the bone or other distant organs-without affecting the rest of the lung.
Lung cancer. Obeys no rules . Direct spread to bones without hilar or mediastinal mets is one broken relatively freqently!

Might it be possible that a local tumor in the lung spread to develop bone metases without affecting the rest of the lungs?

Yes. Some types of lung cancer, especially small cell lung cancer, can spread early and rapidly without growing a large initial mass in the lung. Spread to bone, the breasts, and the brain is most common. The method of spread is by cancer cells breaking away from the tumor and entering the bloodstream or lymphatic circulation; it does not grow into the bone by direct extension. Read more...
