There are many types of lung cancer, and central lung cancer is one of the most common types. There are many reasons why people suffer from central lung cancer, which may be due to environmental factors or smoking. So, what are the symptoms of central lung cancer? Let's take a look at the introduction of this article.

If the symptoms of central lung cancer are obvious, it can be easily identified under normal circumstances, as follows.

1. Coughing up blood and bloody sputum: This is mainly because the surface of the tumor is rich in blood vessels, and coughing causes capillary rupture. The amount of blood is not much, and the blood is bright red, like foam. Coughing up blood is a common symptom of central lung cancer, which often occurs in the middle and late stages. Occasionally, severe coughing up blood occurs.

2. Fever: Lung cancer tumors can cause bronchial obstruction, lumen compression or tumor cavitation, which can cause inflammatory fever in the body. It is a symptom of central lung cancer that is easily misdiagnosed. Special attention should be paid to the diagnosis of this symptom of lung cancer.
