What are the early symptoms of lung cancer?

The early symptoms of lung cancer mainly include cough, low fever, chest pain and blood in sputum. However, a small number of lung cancer patients have no obvious symptoms in the early stages of the disease.

1. Cough

Lung cancer cells will attach to the bronchi and lung tissues, constantly irritating the respiratory tract, causing an immune response in the respiratory tract, and thus triggering an irritating cough.

2. Low fever

A large tumor can block the lung lobe, and the patient is prone to fever. The patient's physical condition is usually more important. In mild cases, it mainly manifests as a low fever; while patients with poor physical condition or severe illness usually manifest as a high fever. Antipyretics can temporarily restore the body temperature to normal, but it usually recurs.

3. Feel chest pain and distension.

Chest pain may occur during the development of lung cancer. The pain is mild in the early stages, mainly manifested as chest dullness and pain, and the location of the pain is not fixed.

4. Blood in sputum

The tumor causes the death of lung tissue cells, rupture of capillaries, and causes a small amount of bleeding, which is mixed with the sputum. Blood can be seen in the sputum, manifesting as intermittent attacks.
