What are the symptoms of central lung cancer? There are 3 symptoms of central lung cancer

Central lung cancer is a more malignant type among all types of lung cancer, and the main cause of the disease is long-term smoking. Nowadays, with the further deterioration of the environment, the incidence of this type of disease continues to grow. In order to better prevent the onset of the disease, it is very helpful to understand the symptoms of central lung cancer.

1. Coughing up blood and bloody sputum

The symptoms of coughing up blood and bloody sputum are mainly due to the abundant blood vessels on the surface of the patient's tumor, and severe coughing is likely to cause the capillary walls in the corresponding part to rupture. If the capillary walls rupture, it will cause coughing up blood and bloody sputum with a small amount of foamy bright red blood. This symptom mostly occurs in the middle and late stages of the disease.

2. Fever

Tumor cells of central lung cancer can cause compression, obstruction, and even cavitation of the patient's bronchial lumen, which in turn can cause inflammation in the body and lead to more severe fever symptoms in patients. This is also the most easily misdiagnosed symptom of central lung cancer. Therefore, when patients are diagnosed, they must pay attention to the importance of fever symptoms.

3. Hoarseness

Most patients with central lung cancer will experience hoarseness in the early stages of the disease, and more than 40% of them suffer from central lung cancer. This shows that this symptom is the most specific and typical one among the symptoms of central lung cancer.

In addition, among the symptoms of central lung cancer, shortness of breath is also a symptom that is easily overlooked by patients, and most patients do not pay enough attention to this symptom, which leads to the further development and deterioration of their condition, making it difficult to control.
