Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is asymmetry of the breast shadows , smaller on the right , with right axillary surgical clips , consistent with prior surgery . The lungs are hyperinflated , suggesting COPD . Heart size is at the upper limits of normal or slightly enlarged . Aorta is minimally unfolded . Prominence of the right heart border and ascending aorta is noted , but is probably similar to the prior study , allowing for technical differences . There is upper zone redistribution , more pronounced than on the prior film , with slight vascular plethora . Minimal blunting of the right costophrenic angle is new . No gross effusion is identified . No pneumothorax is detected . Left apical pleural thickening is unchanged . No focal infiltrate or frank consolidation is identified . Sclerotic densities in the left anterior ribs again noted , in keeping with air is increased activity on bone scan from ___ . .
    OUTPUT:
    
1 . Status post right breast surgery with axillary clips . 2 . Probable background COPD . 3 . Cardiomegaly with prominence of the ascending aorta . Allowing for differences in positioning , this is probably unchanged . 4 . Upper zone redistribution and mild vascular plethora is new compared with the prior film and suggests mild fluid overload . 5 . No pneumothorax or focal infiltrate identified .
