What are the symptoms of lung cancer? What are the specific manifestations of lung cancer?

No obvious symptoms in the early stages: Many patients are already at an advanced stage when they are detected, so it is important to understand the early symptoms for early diagnosis and treatment. Some common early symptoms include:

1. Persistent cough or coughing up blood: A persistent cough can be caused by a lung infection, but a long-standing cough can also be a sign of lung cancer.

2. Dyspnea: If symptoms such as shortness of breath and shortness of breath suddenly appear, it may be caused by the tumor compressing the airway.

3. Fever: Unexplained fever may be one of the manifestations of the body's immune response to cancer cells.

4. Fatigue: Feeling tired for a long time, which cannot be relieved even after adequate rest, may also be related to lung cancer.

5. Symptoms of intracranial metastasis: When lung cancer metastasizes to the head or other parts, it may cause symptoms of intracranial hypertension such as headache, nausea, and vomiting.

6. Cardiovascular system symptoms: Lung cancer may lead to impaired heart function, such as irregular heartbeat, palpitations, etc.

7. Symptoms of liver involvement: Some types of lung cancer can spread to the liver through the blood route, resulting in abnormal liver function, jaundice and other symptoms.

8. Other symptoms: such as weight loss, anemia, joint pain, etc.

If you have any of these symptoms and have smoked for many years or have a family history, see your doctor for a check-up to detect and treat potential lung cancer problems as early as possible.
