The main causes of increased alpha-fetoprotein are primary hepatocellular liver cancer, germinal germinoma, gastric cancer, viral hepatitis, and cirrhosis. Alpha-fetoprotein is a glycoprotein synthesized by the liver in early fetal life, and its synthesis is inhibited after birth. The common causes of elevated alpha fetoprotein are mainly primary hepatocellular liver cancer. The fetoprotein is also elevated to varying degrees in germinal germ tumors, gastric cancer, viral hepatitis and cirrhosis, so don’t be nervous about elevated fetoprotein; it generally has to be more than twice normal to have clinical diagnostic significance. When you have a fetoprotein test, don’t be nervous, don’t be tired, don’t stay up late, and eat more fresh vegetables and fruits and exercise more before the test. If you find that your AFP is elevated, you should have an ultrasound or CT examination of the liver, gallbladder, pancreas, spleen and kidneys, as well as gynecological ultrasound and testicular ultrasound, in order to exclude the occurrence of tumors.
