What are the main items of liver cancer screening? What should I do if I find something unusual?

The diagnosis of liver cancer is not difficult. Liver cancer is one of the few tumors that can be diagnosed clinically. What does clinical diagnosis mean? The diagnosis can be made through physical examination and auxiliary examination. Most tumors can only be diagnosed by pathological diagnosis, that is to say, tissues should be sent to pathology department, and pathologists can only be diagnosed if they find cancer cells under a microscope. Alpha-fetoprotein (AFP): Alpha-fetoprotein is a special protein synthesized by fetal hepatocytes and normally exists in fetal serum. As the first choice for screening liver cancer, B-ultrasound has the advantages of non-invasive, simple, non-radiation, low cost and easy popularization. B-ultrasound can show the size, shape and location of tumor, and whether there is tumor thrombus in hepatic vein or portal vein, and its diagnostic coincidence rate can reach 90%.

CT examination, if there is no problem with ultrasound, at least there will be no major lesions. If you have hepatitis B or liver cirrhosis, it is recommended to do CT examination directly, and enhancement is needed. Liver cancer complicated with cirrhosis, if only one CT scan is done, it is easy to miss the diagnosis. Selective hepatic arteriography When enhanced CT/MRI is difficult to diagnose small suspected liver cancer, selective hepatic arteriography is an important supplementary means for the diagnosis of liver cancer. For small hepatocellular carcinoma with a diameter of 1-2cm, hepatic arteriography can make a more accurate diagnosis, and the correct rate is over 90%.

In the late stage, accompanied by abnormal liver function, edema, liver palm (erythema of thenar of hand becomes pale after pressing) and spider nevus (red spots of skin distribute bloodshot to the surrounding network, which will disappear after pressing) will appear. There are two halves of hepatitis B: There are so many patients with liver cancer in China, and most of them are related to hepatitis B, so it is necessary to improve the hepatitis B examination to see if it is chronic hepatitis B. China is a big country with liver cancer, and the number of new cases and deaths is very high every year. Every year, there are 6.5438+0.2 million deaths due to liver cancer, which is the country with the largest number of liver cancer deaths in the world.
