Lung cancer is a common culprit when it comes to chest pain in cancer patients. As the tumor grows, it can invade nearby structures like the chest wall, causing pain. Metastasis to the pleura, the thin membrane surrounding the lungs, can lead to pleuritic pain, characterized by sharp, stabbing sensations that worsen with breathing or coughing. Additionally, lung cancer patients might experience pain due to complications like pleural effusion, where fluid accumulates around the lungs, or pericardial effusion, where fluid builds up around the heart.
