3. Bone and joint symptoms: This type of symptom is more common. It often affects the tibia, fibula and other bones and joints, and the ends of the fingers and toes. Because lung cancer cells can produce certain special endocrine hormones, antigens and enzymes, these substances act on the bone and joint parts, causing swelling and pain in the bone and joints.

4. Irritating cough: Because lung cancer grows on bronchial lung tissue, patients often have irritating coughs due to respiratory irritation symptoms.

Blood in sputum: Tumor inflammation can cause necrosis and damage to capillaries accompanied by a small amount of bleeding, which is often mixed with sputum and appears intermittently or discontinuously. Once blood in sputum appears, you should seek medical attention immediately and receive a comprehensive examination.
