my husband got the xray the result is suspecious densities in upper right lobe.my question is what is the treatment for these?
It depends on what the "suspicious densities" are. It could be a scar from an old infection OR it could be an infection such as tuberculosis.
He needs further diagnosis. It could be another x-ray, usually an apicolordotic view, to better focus on the tops of the lungs. It may also include a sputum analysis or a biopsy.
