Disease description:

My father-in-law has been a long-time smoker. He was recently diagnosed with lung cancer but did not receive timely treatment. Now he is experiencing chest tightness, and we suspect that the cancer has spread to cause pleural effusion. What are the symptoms of lung cancer that has metastasized to the pleura causing pleural effusion?

The main symptoms of lung cancer metastasizing to pleural effusion include chest pain and chest tightness, which worsen particularly during deep breathing or coughing. As the condition progressively deteriorates, symptoms such as shortness of breath and difficulty breathing may also develop. When the above symptoms occur, it is recommended to seek medical attention early at a nearby tertiary hospital and receive treatment under the guidance of a qualified physician.
