What are the examination items for early lung cancer? Five examination items for early lung cancer

No matter what the disease is, the earlier the diagnosis and treatment, the better. However, the early symptoms of many diseases are not very obvious. Therefore, if you find yourself with similar symptoms, you must go to the hospital for a check-up as soon as possible. So, what are the early examination items for lung cancer? Let's take a look.

1. Bronchoscopy is an effective means of diagnosing lung cancer. Bronchoscopy can directly observe the pathological changes of the bronchial endothelium and lumen, and can observe the location and range of the tumor, obtain tissue for pathological examination, and aspirate bronchial secretions for cytological examination to clarify the diagnosis and determine the histological type. The possibility of surgical resection can also be inferred based on the condition of the vocal cords, trachea and carina.

2. Chest X-ray is the most basic and classic examination item in the diagnosis of lung cancer, and it is also an indispensable reference for all other examination items. In the relevant examinations of early lung cancer, chest X-ray frontal and lateral images can show the basic elements such as the location, size, shape, density and relationship with surrounding tissues of most lung lesions. Doctors can make preliminary judgments based on these basic parameters, and some patients can also make a more certain clinical diagnosis based on chest X-ray. If some high-risk groups have unclear chest X-rays and have symptoms such as repeated irritating dry coughs, blood in sputum, chest pain, chest tightness and shortness of breath, further examinations such as sputum cytology, chest CT or fiber bronchoscopy should be performed.

3. The main purpose of B-ultrasound examination is to understand whether there is metastasis to the liver, spleen, kidneys, adrenal glands, retroperitoneal lymph nodes or cervical lymph nodes. It is one of the important auxiliary examinations in the diagnosis of lung cancer. It can be widely used in surveys for first-time patients, follow-up patients and high-risk groups.

4. CT examination has been widely used in clinical practice. Chest CT examination makes the mediastinum, hilum and other areas more clearly visible, making up for the shortcomings of ordinary chest X-rays, and plays a huge role in the clinical diagnosis, staging, formulation of treatment plans and selection of surgical procedures of lung cancer. In the relevant examinations for early lung cancer, it should be pointed out that chest CT examination cannot replace chest X-rays. Chest X-rays should be taken first and then chest CT examinations. The two complement and refer to each other.

5. Sputum cytology is a very promising test item. It is simple to operate, non-invasive, low-cost, and can be repeated many times. However, the positive rate of this test is not high at present. The main problem is that there may be some problems in the collection of specimens, preparation of slides, staining and reading of slides. In recent years, the intervention of computer-assisted systems has greatly improved the effect of this test.

Experts remind: The earlier the examination, the more helpful it is for treating the disease. Only by confirming the disease as early as possible can we determine the specific treatment plan. This is very useful for controlling the disease. Therefore, it is a fundamental condition for lung cancer patients to seek medical treatment as soon as possible to cure the disease. I hope everyone can remember this.
