Lung effusion? Lung cancer?

Fluid in the lungs, also known as pleural effusion or hydrothorax, refers to the lungs and pleural spaces showing a lot of fluid. The main causes include tuberculosis, pneumonia, tumor metastasis to the pleura, surgery, filariasis, hypoproteinemia, etc. When the elderly are examined, pleural effusion is found, which is more common in lung cancer. However, as long as the patient checks out pleural effusion, blood tests, chest CT and fluid extraction for laboratory tests are required to confirm the disease, and on this basis, actively cooperate with doctors for treatment.
