Will lung cancer definitely cause coughing up blood?

1. Lung cancer does not necessarily cause coughing up blood. Coughing up blood is just a symptom of lung cancer. However, due to the differences in disease progression and physical function after each person has lung cancer, some lung cancer patients may not experience symptoms of coughing up blood. Lung cancer cannot be diagnosed clinically by the symptom of coughing up blood.

2. Lung cancer usually causes persistent fever, weight loss, fatigue in the limbs, chest tightness and shortness of breath, and long-term coughing. Some people may even cough up blood or have blood in their sputum. Due to the differences in body length and degree of progression after each person is diagnosed with the disease, lung cancer may not cause coughing up blood. When physical symptoms are suspected to be related to lung cancer, it is recommended to actively cooperate with the doctor to complete relevant imaging and pathological examinations, and cooperate with the doctor for symptomatic treatment after the cause is identified.

3. When lung cancer appears but there is no symptom of coughing up blood, it does not mean that the lung cancer is mild. You still need to cooperate with the doctor for standardized treatment. Because there are many types of lung cancer, different types of lung cancer will have slightly different clinical manifestations, so relevant imaging and pathological examinations should be carried out.
