What are the early symptoms of lung cancer? 4 symptoms tell you that lung cancer is coming

Lung cancer is a disease that we all know well. It is a common disease in our lives. Many patients are diagnosed with lung cancer in the late stage, which is closely related to the fact that the early symptoms of lung cancer are not very obvious. Today, let's take a look at some of the early symptoms of lung cancer. Let's continue reading.

1. Irritating cough

In the early stages of lung cancer, a typical symptom is an irritating cough, which can easily be misdiagnosed as chronic bronchitis. Its early manifestation is mainly a dry cough, which will gradually become more severe over time. Many patients will use anti-inflammatory drugs for treatment at this time, but they often do not have a good therapeutic effect. The treatment is not in the throat but in the lungs. As the disease progresses, symptoms such as coughing with sputum and hemoptysis will appear. Because when the lung cancer mass protrudes from the lumen in the body, the shedding of tumor cells may cause bleeding. If it invades large blood vessels, it will also cause severe hemoptysis.

2. Chest tightness and pain

In the early stage of lung cancer, chest tightness and chest pain may occur. Many people think that these symptoms are caused by heart abnormalities. In fact, it is not. Lung cancer can also cause chest tightness and chest pain, and the chest pain caused by lung cancer usually manifests as irregular chest dull pain or dull pain. Sometimes it manifests as chest tightness and discomfort, sometimes it is accompanied by tingling, and some more serious cases may involve discomfort in the back.

3. Recurrent pneumonia

After contracting lung cancer, patients are also very likely to have lung infections. After a period of anti-inflammatory treatment, the symptoms will be relieved, which makes many patients have the illusion that they have recovered. In fact, the tumor has not been eliminated, and pneumonia will continue to occur after a period of time. If you have recurrent pneumonia, it is likely caused by lung cancer.

4. Difficulty breathing

In the early stages of lung cancer, patients may experience mild dyspnea. Similar to the feeling of difficulty breathing and throat discomfort, these symptoms can easily be mistaken for pharyngitis. As time goes by, the tumor will become larger and larger, the airway obstruction will become more and more serious, and the dyspnea phenomenon will become more and more obvious. This is a very common symptom of lung cancer.
