How long is the incubation period of lung cancer? It is divided into accumulation period and precancerous period

Lung cancer is a malignant tumor that originates from the bronchial mucosa or glands. Coughing is usually an early symptom of lung cancer. The incubation period of lung cancer is usually divided into the accumulation period and the precancerous period, which may take several years to decades.

The early symptoms of lung cancer are not very obvious. Typical symptoms are cough, chest tightness and blood in sputum. Once the above symptoms appear, timely examination should be carried out to achieve the purpose of early detection and treatment. So, how long is the incubation period of lung cancer?
There are several different types of lung cancer, including squamous cell carcinoma, adenocarcinoma, small cell lung cancer, and some also include large cell lung cancer. Due to their different pathologies, their incubation periods are also different. Some lung cancers cannot be seen in the early stages and there are no symptoms. Only when the tumor grows larger will some clinical symptoms appear.
The incubation period of lung cancer is usually about two to ten years, which is roughly divided into the accumulation period and the precancerous period. Usually, the early symptoms of lung cancer are not too obvious, and the typical symptoms are coughing and chest tightness or blood in sputum.
The early symptoms of lung cancer are not obvious and difficult to detect. Most patients are already in the late stage when they are discovered, and treatment is very difficult, and recovery is even more difficult. Many people are concerned about the survival rate of lung cancer in the late stage. In fact, it is more important to pay attention to the patient's quality of life. Patients with advanced lung cancer will have many symptoms. In order to alleviate these symptoms, Chinese medicine can be used for treatment.
