The most noticeably elevated blood test for liver cancer is AFP, which is alpha-fetoprotein. Alpha-fetoprotein is a component synthesized in the fetal liver, and it basically drops to normal in adults. However, alpha-fetoprotein reappears to proliferate during the growth of cancerous cells in liver cancer. When liver cells become cancerous, they resume producing this protein again, and the amount of this alpha-fetoprotein increases dramatically as the disease worsens. Therefore, in the examination for diagnosing liver cancer, AFP has become an important indicator for checking and screening liver cancer. Secondly, in the process of liver damage of liver cancer, it can also lead to the elevation of glutamic oxaloacetic aminotransferase and glutamic alanine aminotransferase, which are mainly found in the mitochondria of liver cells and the cytoplasm of liver cells, and the damage of liver cells can easily lead to the situation that the two kinds of aminotransferases will reach the elevated concentration in the blood after entering into the blood.
