What are the symptoms of lung cancer? Lung cancer patients often have these three symptoms

Lung cancer is a malignant disease that affects a lot of people. This cancer causes many patients to lose their lives every year. Some patients are suffering from the disease but fail to detect it in the early stages, so they do not receive timely treatment, which leads to worsening of the disease and incurability. Therefore, everyone should carefully understand the symptoms of lung cancer.

1. Cough

When the malignant tumor of lung cancer spreads to the patient's bronchi, it will compress and irritate the respiratory tract and cause an irritating cough. This is also the most easily overlooked symptom of lung cancer that needs to be vigilant. The symptom is mostly manifested as an intermittent cough without sputum in the early stage, but once infected, sputum will be produced.

2. Blood in sputum

Lung cancer tumors can destroy other healthy tissue cells, which may cause capillary damage and bleeding, resulting in blood in the sputum. This lung cancer symptom that requires vigilance is often intermittent, and most patients only realize their condition because of this symptom and rush to see a doctor.

3. Fever.

Many diseases will cause fever in the patient's body, and lung cancer is no exception. The symptoms of fever will show different degrees depending on the patient's specific condition. The milder ones are generally low-grade fever, while the more serious ones are high-grade fever. After taking medicine, the fever symptoms can be temporarily relieved, but they are very likely to recur.

There are many symptoms of lung cancer, and shortness of breath is also a symptom of lung cancer that needs to be vigilant. The main reason for this symptom is that the lung function is affected by the tumor of lung cancer, especially when the patient is overworked, the patient will feel even more shortness of breath and may even go into shock.
