How to diagnose small cell lung cancer

How to diagnose small cell lung cancer? With the development of society, many people are very dependent on electronic products, resulting in more and more people suffering from small cell lung cancer. If not treated in time, it will cause very serious consequences. So how to diagnose small cell lung cancer? Let's discuss it together.

The clinical symptoms obtained through comprehensive analysis of various imaging results are an effective basis for diagnosing lung cancer, but only a diagnosis based on pathological histology or cytology can finally confirm the disease. The diagnosis based on this evidence cannot be considered a confirmed diagnosis. The clinical diagnosis of non-small cell lung cancer is generally based on the principle of going from non-invasive to invasive, and from simple to complex.

(a) X-ray examination

It is still an important basic method for discovering and diagnosing lung cancer and providing treatment reference. Commonly used X-ray examination methods include chest X-ray fluoroscopy, chest anteroposterior and lateral films, and tomographic films.

(B) CT examination

Chest CT examination has become a routine method for estimating the extent and range of lung cancer intrathoracic invasion, especially in the staging of lung cancer, and it has an irreplaceable role. CT examinations of other parts, including the brain, liver, and adrenal glands, are mainly aimed at excluding distant metastasis to lung cancer-related parts. Generally, the examination is performed only when metastasis is suspected clinically.

3. MRI examination

The biggest feature of chest MRI examination is that it is easier to identify the relationship between solid masses and blood vessels than CT, and it can show the compression, displacement and obstruction of the trachea, bronchi and blood vessels.

(IV) PET-CT examination

This test is relatively expensive and is mainly used to exclude mediastinal lymph node and distant metastasis.

5. Histological or cytological examination of lung cancer

The diagnosis of lung cancer must be based on histology or cytology. Cytology is one of the important methods for diagnosing lung cancer and is also the simplest and most convenient diagnostic method. According to the source of the specimen, it can be divided into sputum cytology, pleural effusion cancer cell cytology, percutaneous fine needle lung puncture cytology, and puncture smear cytology of enlarged supraclavicular lymph nodes or subcutaneous nodules. Clinicians can make choices based on the conditions of different patients.
