How to determine lung cancer and how to determine whether you are lung cancer?

Chest X-ray, chest CT, scan, pulmonoscopy. After this series of physical examinations, it can be basically determined.

CT and X-rays and, if necessary, biopsy.

The diagnosis can be confirmed by tracheoscopy.

Bronchoscopy is done for tissue biopsy.

Lung cancer is suspected if the patient has a cough with blood in the sputum and has smoked for more than 20 years, and the diagnosis depends on CT and biopsy if necessary.

Whether it is a tumor in the cavity or a nodule in the lung, it cannot be said that it is lung cancer as soon as it is found, there must be a cytological biopsy, the current gold standard for diagnosing lung cancer or pathological histopathology and histological examination, the small nodules in the lung have been seen cancer cells through puncture, the diagnosis of lung cancer is benign adenoma in the bronchi, squamous cell carcinoma cells have been seen through puncture, and small cell lung cancer has been seen, we say that he has been diagnosed with lung cancer, so this cytopathological diagnosis is the gold standard.

Hello, the clinical manifestations of lung cancer mainly include 1Cough 2Blood in sputum or hemoptysis3Chest pain 4Chest tightness, shortness of breath, 5Hoarseness. It is recommended that you go to the hospital as soon as possible to check whether this is the case, and then treat the symptoms**.

First, go to the hospital for a CT to check the tumor markers. If there is a problem with the lungs, CT-guided percutaneous lung biopsy can be done for pathology to further confirm the diagnosis. Pathology is the gold standard for diagnosing tumors.

Go to the hospital for a CT check, check the blood, how can you go to the hospital if you are afraid, your current age is not expected to be, adjust your mentality, be optimistic and positive.

There are several main methods of lung cancer screening:

1. Chest fluoroscopy and radiograph, you can see changeable circular shadows, pneumonia, atelectasis, pleural effusion, etc. Chest tomography X-ray, CT and MRI can be used to understand the relationship between the size of the tumor and the lobes, lung segments, and bronchi. Bronchoiodine angiography may be done if necessary.

2. Repeated sputum detection of cancer cells can obtain positive results, which has diagnostic value.

3. Bronchoscopy can directly observe the lesions, and at the same time, biopsy pathological examination and bronchial secretion smear can be taken to check for cancer cells.

4. If the lung puncture positioning is accurate, the puncture smear examination can generally obtain positive results, which has diagnostic value.

5. Superficial lymph node puncture or biopsy: When lung cancer with lung lesions to be confirmed or accompanied by upper mediastinal widening, lymph nodes palpable on the neck, clavicle, suspicious subcutaneous masses, and suspicious cancerous lymph nodes in other parts can be aspirated or biopsied to obtain a pathological histological diagnosis.

There are as many as 11 ways to diagnose lung cancer, but not every patient has to complete 12 kinds of examinations, and the examination should be carried out according to the actual situation of the patient

1. Chest X-ray: It is an important means to diagnose lung cancer, and the shadow of the lungs can be found through fluoroscopy or anterolateral chest X-ray.

2. Chest CT: It can detect and clearly show the size, shape and accumulation range of lesions in the hila, lung and mediastinum, which is helpful for diagnosing whether lung cancer can be resected.

3. Magnetic resonance imaging (MRI): to determine the extent and stage of lung cancer invasion and the possibility of surgical resection.

4. Positron emission computed tomography (PET): It helps to distinguish the benign and malignant tumors.

5. Sputum cell examination: Some lung cancer patients can be diagnosed through sputum examination, and the histological type of lung cancer can be judged at the same time, but it is necessary to examine 4 to 6 times in a row to obtain the results.

6. Flexible bronchoscopy: pathological diagnosis can be obtained, which is helpful for determining the scope of lesions and clarifying surgical guidelines and methods.

8. Percutaneous lung biopsy: suitable for patients with sputum cytology and bronchoscopy who cannot obtain positive results, small peripheral masses and new peripheral lung lesions, lesions with unclear growth history, multiple nodular lesions in the lungs, patients with a tendency to not be able to do so, and lesions that do not need to be resected.

9. Mediastinoscopy: It is conducive to the diagnosis and TNM staging of tumors.

10. Thoracoscopy: mainly used to determine the nature of pleural effusion or pleural mass.

11. Detection of serum tumor markers: the existence of malignant lesions can be indirectly judged by the detection of unique substances secreted into the blood by lesions.
