How to sample lung cancer slice

First, early lung cancer generally does not produce symptoms, so it is also called asymptomatic period, which can be as short as several months and as long as several years. It varies from person to person. Some of the early symptoms of lung cancer are just general respiratory symptoms such as dry cough, chest pain, low fever and hemoptysis. These symptoms are confused with cold, bronchitis and pulmonary inflammation, so it is difficult to find them clinically. In addition to those symptoms, due to the compression of lung cancer on other nerves, most of the external signs will also show. It is recommended that patients should seek medical examination and diagnosis in time once they find similar symptoms.

Second: the lung cancer specimens were sent to the pathology department for fixed overnight. The next day, the specimens were taken. The third day, the slices were stained. The fourth day, the pathologist read the slices. The fifth day, the immunohistochemical examination was done. The sixth day, the report was issued. Sometimes, the supplementary materials were taken and the slices were made. This is the fastest speed.

Third: pathological section refers to one of the processes of pathological examination. It basically means the same thing. The process of pathological examination is: first, the tissue is taken, then dehydrated, then embedded, and then sectioned, and then stained. After staining, the pathological examination under the microscope can be carried out. Therefore, what we usually call pathological section examination actually refers to routine pathological examination.

matters needing attention

At present, the most reliable way to diagnose tumor is to make pathological section. But the pathological section is not 100% accurate, which is mainly due to the difference that the most ideal part is not taken in the process of puncture. Therefore, it is generally necessary to take multiple tissues at one time to make a definite diagnosis.
