How to diagnose peripheral lung cancer? 3 tests to diagnose peripheral lung cancer

Peripheral lung cancer is a type of lung cancer. The lesions of this type of lung cancer are usually located around the bronchi, which may cause patients to experience symptoms such as coughing up blood and chest pain. The diagnosis of peripheral lung cancer can be confirmed in a timely manner through auxiliary examinations such as imaging examinations, pathological examinations, and carcinoembryonic antigen examinations. This can help understand the condition in a timely manner and provide guidance for treatment.

Lung cancer is a malignant tumor disease. Since the lungs have a very rich blood supply, once lung cancer occurs, local normal lung tissue will be severely damaged, the patient's lung function will also decline, and hypoxia will occur. Lung cancer usually includes two main types: central and peripheral. The main manifestation is the difference in the location of the lesion. Peripheral lung cancer may be relatively more malignant and requires effective treatment as soon as possible. The following three auxiliary examinations can be performed for peripheral lung cancer, which can usually be diagnosed in time.

1. Imaging examination

Diagnosis of lung cancer mainly involves imaging examinations, such as X-ray, CT, and MRI, which can clearly show the location and size of local lesions, as well as the boundary with surrounding tissues. Currently, there is also a more advanced pETCT, which is a radionuclide examination, which can provide a clearer diagnosis of local lesions.

2. Pathological examination

If the specific location of the diseased tissue is found through imaging examination, fine needle aspiration can be performed to obtain the diseased tissue if necessary, and then a pathological section examination can be performed. This examination method is more intuitive and can distinguish the nature of the tissue in detail, which is very helpful in judging the malignancy of lung cancer.

3. Carcinoembryonic antigen test

This test can usually be done through blood tests. Cancer cells secrete and produce some specific antibodies during their growth and development. Carcinoembryonic antigen tests can detect these antibodies in time, thereby diagnosing peripheral lung cancer in time.

There are generally three effective examination methods for peripheral lung cancer. If you experience symptoms such as coughing up blood, chest pain, low fever, etc., timely examinations can help you make a clear diagnosis. After early and timely diagnosis, peripheral lung cancer usually requires timely surgical resection, and combined with postoperative radiotherapy and chemotherapy, which will have a good treatment effect. Patients should also pay attention to developing good living habits and pay attention to regular checkups to prevent recurrence of the disease.
