What are the classifications of lung cancer? How to clearly diagnose the classification of lung cancer?

Lung cancer is a malignant tumor of the respiratory system. Lung cancer patients have no obvious symptoms in the early stage, or the symptoms are mild and often easily ignored. In the late stage, they will experience chest tightness, shortness of breath, abnormal hemoptysis, etc. In addition, in the late stage, malignant tumors of organs throughout the body may metastasize to the lungs, thereby aggravating the severity of lung cancer and the difficulty of treating lung cancer. Most of the time, the treatment of lung cancer is delayed because patients lack relevant knowledge about lung cancer. Now, Zhou Chengzhi, chief physician of the First Affiliated Hospital of Guangzhou Medical University, will popularize relevant knowledge for us.

What are the classifications of lung cancer?

Lung cancer can be divided into small cell lung cancer and non-small cell lung cancer according to pathological classification. With the increasingly detailed understanding of the biological behavior of tumors, non-small cell lung cancer is divided into three categories according to different characteristics under the pathological optical microscope: squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. The treatment principles are not much different. In the early stage, surgical treatment is adopted. The treatment is mainly different in the middle and late stages, local advanced stage or advanced stage.

How to clearly diagnose the classification of lung cancer?

At present, the conventional pathological classification of lung cancer is based on the characteristics under an optical microscope. Therefore, when a lesion is found in the lung, the tissue needs to be removed by means of a method. After the tissue is removed, the morphology and tissue structure of the cells are observed under an optical microscope, and specific pathological classification is performed based on the morphology and tissue structure of the cells. Sometimes, when the differentiation is poor, special protein immune markers are also needed to distinguish them.

When we frequently experience symptoms such as chest tightness, shortness of breath, and chest pain, it is very likely related to lung cancer. At this time, we need to go to the hospital for examination, determine the cause, and then treat the symptoms. Once you are unfortunately ill, you should not face it negatively. There are many types of surgeries for lung cancer. If it does not develop to the late stage of lung cancer, the cure rate of most patients is still very high. Patients who have undergone surgical treatment should have regular checkups to prevent cancer recurrence and metastasis. After receiving active treatment, there will be no problem in carrying out general activities, life and work.
