How to check for lung cancer What are the tests for lung cancer?

Hello! If lung cancer is suspected, go to a regular hospital for examination and diagnosis in time, and if so, it can be diagnosed in time (early lung cancer can be cured, but advanced lung cancer is difficult to treat); If not, it's better to go to a heart disease and relieve the burden of thought.

If lung cancer is suspected, the following tests are often done:

1.sputum cytology;

Anterior and lateral radiographs of the chest to observe the shape and location of the mass.

3.Chest CT scan, in addition to understanding the location and morphology of the mass, can also measure the CT value, if done with enhanced CT is more accurate.

4.Flexible bronchoscopy.

5.Percutaneous lung biopsy can directly obtain pathological diagnostic results.

Only fibrobronchoscopy is donePercutaneous lung biopsy is required to confirm the diagnosis of lung cancer and the specific type of lung cancer.

Hello, your symptoms are not like the symptoms of lung tumors. Change your smoking habits. Wear a mask at work to prevent dust inhalation. If in doubt, sputum can be examined, and a blood test can be done with an MRI to confirm the diagnosis.

This is to go to the hospital to do a pathology, CT examination can be judged, lung cancer is still surgery, and at the same time with some traditional Chinese medicine, the effect will be better, such as traditional Chinese medicine.

Tests for lung cancer include: Imaging tests: general chest x-ray, chest CT, MRI, SPECT, PET; sputum exfoliated cell test; bronchoscopy; transthoracic fine-needle biopsy; mediastinoscopy; thoracoscopy; Other cellular or pathological tests; open lung biopsy; Tumor marker testing.

Imaging examination is a common and valuable method to detect lung cancer, and cytology and pathological examination are necessary means to confirm the diagnosis of lung cancer.

Chest imaging examinations, including chest X-ray, CT, etc., are required after lung cancer is suspected. If lung cancer is suspected, bronchoscopy, biopsy of lesions or metastases, mediastinoscopy or thoracoscopy, and/or sputum cytology should be performed to confirm histopathologic or cytologic diagnosis.

It should not be performed before the pathological tissue or cytological diagnosis**, and even if the pathological or cytological diagnosis is confirmed, the correct method should be performed after the staging examination has confirmed the staging. Sometimes, what appears to be a resectable early lesion, such as a peripheral type of 1 to 3 cm in diameter, but after staging, asymptomatic metastases to the brain or bone or other advanced lesions are detected,** the approach is very different.

I wish all patients a speedy day**.

Depending on the situation, you can find sputum exfoliation cytology for examination and diagnosis, and save some money. If this is not possible, a bronchoscopy or CT biopsy will be done.

Go to the hospital to do enhanced CT directly (one step, save the hospital more money). Then do a puncture and you can make sure.

If it can be detected and standardized in any stage, the rate of lung cancer can reach 70%, but the current reality is that the total clinical rate of lung cancer patients is only 15%, and the inability to detect it early is a fundamental problem.

The morbidity and mortality of pulmonary pain are now ranked first among all malignant tumors. The World Health Organization warned in 2001 that in the past 10 years, the global incidence of lung cancer has been increasing rapidly at a rate of 22 per year, with 1.2 million new patients with lung pain and 1.1 million deaths worldwide every year. The mortality rate of lung cancer in China exceeds that of gastric cancer and liver cancer, ranking first among all kinds of tumor diseases.

The "Death Map of the Chinese Population" shows that between 1991 and 2000, the mortality rate from lung cancer increased significantly among men, especially among people aged 35 to 69 years. With the aging of the population and the intensification of urban industrialization, as well as the pollution and destruction of the human living environment, especially the increasing number of smokers, the incidence and mortality of lung cancer in China will continue to rise in the next 20 years.

From 2000 to 2005, the number of lung cancer in China will increase by 120,000, of which men will increase from 260,000 to 330,000. The number of women increased from 120,000 to 170,000. There are 100 million smokers in China, and the number of female and underage smokers is increasing year by year. If China's current smoking situation does not change, nearly 100 million men under the age of 29 will die from smoking in middle age or old age by 2050, and millions of women will die.

Early diagnosis is crucial. Lung cancer often shows clinical symptoms at an advanced stage, so only about 15 cases of lung cancer can be diagnosed early before the cancer cells have dispersed to nearby lymph nodes or other sites. The 5-year survival rate of lung cancer patients without lymph node metastasis can reach 50.

Unfortunately, in many patients, the cancer has spread before the diagnosis is definitively determined by the available tests. For patients with early-stage lung cancer who were detected and underwent surgery before the cancer cells had spread, the average survival rate was satisfactory; However, only 15% of lung cancer patients can be diagnosed at an early stage. 70% of 80% of lung cancer patients are already in the middle or advanced stage at the time of presentation, losing the best chance, and the five-year survival rate is very low; Therefore, early diagnosis of lung tumors is crucial.

Many early stage lung cancer diagnoses are accidental, and they are discovered during a cancer check-up. Screening for lung cancer. Screening refers to routine physical examinations for people who have no symptoms, and lung cancer is often detected before symptoms appear.

Therefore, early diagnosis and effective screening for lung cancer can save the lives of many patients. (Chen Bai from the 363rd issue of "Cancer Prevention News").

Hello, there are no obvious symptoms of early lung cancer, once there is a long-term cough, blood in the sputum or hemoptysis, chest pain, chest tightness and shortness of breath, hoarseness, lung cancer can be considered. If you are diagnosed, you will have to go to the hospital for further examination, don't worry too much about lung cancer, and learn the brave and upward spirit of learning (Liu Yi's journey of cancer) will definitely get better.

Although new examination methods are constantly emerging, they can never completely replace the role of chest X-ray, and it is still the most effective and economical examination method. More than 98% of lung cancer patients can detect abnormalities on chest x-ray. In addition, chest dynamic fluoroscopy can compensate for some deficiencies in chest x-rays, which can detect abnormal cardiac shadows and diaphragm muscle activity, which can help in diagnosis.

2) Computed tomography (CT): CT is a supplement to X-ray examination, but can not replace X-ray examination, chest cross-section can more clearly show mediastinal or proximal mediastinal masses and enlarged lymph nodes, and the lung masses of about 1cm are clearer than X-rays. It can also show more clearly the relationship between the tumor and the chest wall and the extent of invasion, which is necessary in patients who are able to do so.

3) Magnetic resonance tomography (MRI): It is a kind of examination without radiation damage, which can not only show intrathoracic structures in a cross-sectional section, but also display in sagittal section and coronal section, that is, it can judge the mass in many aspects and directions. It does not require contrast to directly show the movement of blood vessels.

4) Sputum exfoliation cell examination: This is one of the important methods for lung cancer diagnosis, and the positive rate of exfoliated cancer cells in sputum can reach 60% to 80%. However, it is necessary to pay attention to the quality of sputum specimens, and the general requirement is to get up in the morning with the first deep cough of sputum, and it should be checked for more than 3 consecutive days.

5) Flexible bronchoscopy: The diagnostic value of flexible bronchoscopy is considerable, it can see the lesion and take biopsy for pathological examination, and can understand the location of the lesion in the bronchi, so as to determine the scope and type of surgical resection. Flexible bronchoscopy is now used as a routine test.

6) Percutaneous lung biopsy: It has a high diagnostic value for tumors, is relatively safe, and is generally performed under X-ray fluoroscopy, but can also be carried out under B-ultrasound or CT guidance, with a positive rate of more than 80%. Recommended Reading:
