Large left pleural effusion with multiple soft tissue denisties, pleurally based nodules of tumor. Note only on the left side (site of breast cancer).
Breast cancer seems to be able to spread into the pleural cavity on the same side (ipsilateral) probably via chest wall lymphatics. These parietal pleura-based nodules cause a reactive effusion requiring percutaneous drainage and pleurodesis to prevent reaccumulation.
