The easiest and most effective way to diagnose lung cancer at an early stage is:

a. Diagnostic imaging b. Sputum exfoliation cell test C. Flexible bronchoscopy and ultrafiber bronchoscopy d Anti-human lung cancer monoclonal antibody test e Bronchoalveolar lavage.

What is the method of early diagnosis of tumors.

Answer]: B sputum exfoliation cytology to find cancer cells is a simple and effective way to diagnose early lung cancer.

Answer]: The common and main means of diagnosing lung cancer is chest X-ray, and most lung cancers can be clinically diagnosed by X-ray and CT examination. Sputum cytology should be collected for 3 consecutive days in the morning, and the positive rate is 80, but there are false positives about 1 3.

Fiber bronchoscopy can see the tumor in central lung cancer, and biopsy or brush examination is taken under direct vision, and the positive rate is 80. Pleural effusion examination can be performed in patients with pleural effusion, and the positive detection rate is 38 80. Transthoracic biopsy is used for peripheral lung cancer, which is performed under the guidance of X-ray fluoroscopy, closed grip CT or B-ultrasound, with a positive rate of 70 90, but there are complications such as pneumothorax, hemorrhage, infection, and cancer cell implantation along the needle path.

Examination methods for lung cancer: X-ray, exfoliated cells, flexible bronchoscopy, mediastinal calveautry, thoracoscopy, lifting pathology, tumor markers.

Answer]: B Solution: Chest X-ray examination is the simplest, economical, safe, and commonly used auxiliary examination method for the diagnosis of lung cancer.

The methods are: making trouble.

1) Early clinical manifestations: In the early stage of lung cancer, symptoms such as cough and blood in sputum can appear, but there are also a few cases that can be asymptomatic at all.

2) X-ray examination: X-ray chest X-ray screening for residents over 40 years old is the most effective method for early detection of lung cancer.

3) Sputum cytology examination of lung cancer: It can detect the occult lung cancer that has not yet formed a shadow of a swollen lump under the X-ray, and can detect cancer cells to determine the type of lung cancer.

4) Bronchoscopy: In addition to observing the bronchial condition, tissues can also be taken at suspicious sites for pathological examination or smear smear by suctioning their secretions to check for cancer cells to further confirm the diagnosis.

Lung cancer is a serious disease, there are mild and serious, severe lung cancer will have headache or vomiting these symptoms, the more common sometimes will be severe pain, in the morning or when resting, severe will appear frequent vomiting, early detection, as soon as possible**.

What are the best ways to get lung cancer in the early stages?

Early-stage lung cancer often requires surgery**. If the patient with early-stage lung cancer is in good physical condition and there are no contraindications to surgery, this situation requires aggressive surgery**. Patients with early resection of lung tumors are likely to survive for a long time and may even reach clinical **, so patients with early-stage lung cancer advocate aggressive surgery**.

In patients with early-stage lung cancer, if the patient's lung function is relatively poor and cannot tolerate surgery, radiotherapy can be considered**. Stereotactic body radiation** can be given, which is a special type of radiotherapy. <>

Can lung cancer be completely **?

There are not many advanced methods for advanced lung cancer, because the best time has been missed, and conservative methods are generally used, such as surgery, chemotherapy, radiotherapy, etc., which are easy to increase the pain of patients and difficult to achieve good results. Squamous cell carcinoma of the lung grows slowly, and as long as the patient is in a good state of mind, he can generally survive with the tumor for a long time. In the advanced stage of lung cancer, methods that do not increase the patient's pain are generally adopted, such as traditional Chinese medicine, immunity, etc.

To check for lung cancer, do you need to check your body**?

After lung cancer is diagnosed, immunohistochemistry is sometimes needed to further assist in determining the pathological type of lung cancer. If it is non-small cell lung cancer, genetic testing is also required to determine whether there is a mutation in the driver gene. If advanced non-small cell lung cancer is accompanied by a mutation in the driver gene, it can be performed with oral targeted drugs**, and these tests are important to guide us**.

In addition, patients with lung cancer also need to undergo skull MRI, upper abdomen CT and other related examinations to further rule out distant metastases. <>

1. X-ray examination: X-ray examination is the most commonly used and important means to diagnose lung cancer. X-rays can be used to determine the location and size of lung cancer.

X-rays of early-stage lung cancer may not show a mass, but may show focal emphysema, atelectasis, or invasive lesions in the vicinity of the lesion due to bronchial obstruction, or inflammation of the lungs.

2. Bronchoscopy: Bronchoscopy is an important measure for the diagnosis of lung cancer. Bronchoscopy can directly observe the pathological changes of bronchial intima and lumen.

If cancer or cancerous invasion is seen, tissue can be taken for pathological biopsy examination, or bronchial secretions can be aspirated for cytology to confirm the diagnosis and determine the histological type.

3. Radionuclide examination: 67GA-citrate and other radiopharmaceuticals have affinity for lung cancer and its metastases, and can be concentrated in the cancer after intravenous injection, which can be used for the localization of lung cancer, showing the scope of cancer, and the positive rate can reach about 90.

4. Cytological examination: most primary lung cancer patients can find the exfoliated cancer cells in the sputum, and the histological type of cancer cells can be determined. Therefore, sputum cytology is a simple and effective method for lung cancer screening and diagnosis.

**The positive rate of sputum cytology for type 1 lung cancer can reach 70 90, while the positive rate of sputum test for peripheral lung cancer is only about 50, so the possibility of lung cancer cannot be ruled out in patients with negative sputum cytology.

Measures to enable early diagnosis of lung cancer include the following examinations to help in diagnosis. The first is the examination of symptoms and signs, if there are symptoms of cough, phlegm and blood, chest pain, and wheezing, it is necessary to carry out relevant lung examinations in time to get a diagnosis. The second is to carry out medical examinations, including sputum exfoliation cytology, hematological tumor marker examination, and pulmonary general and enhanced CT examination.

Cancer can be confirmed by blood drawing and chemotherapy, CT can be used to confirm the diagnosis, urine routine can be used to confirm the diagnosis, and the diagnosis can also be confirmed by blood routine, and this method is also the most accurate, and it can be diagnosed with CT.

The corresponding indicators will be tested, biopsies will be performed, saliva will be tested, x-rays will be taken, and CT can also be used.

Lung cancer generally has no obvious symptoms in the early stage, and regular screening of high-risk groups is required, and early diagnosis through pathology.

1.High-risk groups: Patients with a history of smoking, working in industrial production or mining areas, radioactive carcinogens such as asbestos and chromium, history of malignant tumors, family history of lung cancer, or history of chronic obstructive pulmonary emphysema or pulmonary fibrosis should be screened regularly to facilitate early detection and early diagnosis.

Such as chest CT with contrast, magnetic resonance imaging (MRI), etc.

2.Pathological examination: is the final criterion for determining lung cancer.

Common methods such as sputum cytology, which can diagnose type ** lung cancer, are simple and non-invasive, but have a low positive rate. Thoracentesis is a puncture of pleural effusion to obtain pathology, and the examination results are more accurate. Thoracoscopy not only resects the lesion, but also confirms the diagnosis.

For patients with lung nodules, it is recommended to follow the doctor's instructions for follow-up examinations under the guidance of a medical professional. Lung cancer can be diagnosed by pathological examination, and the combination of imaging examination and pathological examination can confirm the staging of lung cancer.
