A mildly elevated alpha-fetoprotein is not necessarily an early stage liver cancer. Elevated alpha-fetoprotein can be seen in a variety of conditions. For example, elevated alpha-fetoprotein can be seen in some normal human bodies, patients with liver disease, gynecological tumors, and patients with other digestive system tumors. 1. Liver cancer: alpha-fetoprotein is one of the tumor markers of liver cancer. When liver cells develop malignant changes, related genes will be reactivated and secrete alpha-fetoprotein into the patient’s blood. For patients with combined liver diseases, if elevated alpha-fetoprotein is found in the examination, attention should be paid to the occurrence of liver cancer. 2. Normal human body: it is normal to see elevated alpha-fetoprotein in newborn babies and pregnant women during pregnancy. 3. Gynecological tumors: for some gynecological tumors, such as ovarian cancer, yolk sac tumor, etc., elevated alpha-fetoprotein can also be seen. 4. Patients with liver disease: for some patients with chronic hepatitis and cirrhosis, the elevation of alpha-fetoprotein can also be seen. However, it is mostly transient elevation. 5. Other digestive system tumors: for example, pancreatic cancer, stomach cancer, colon cancer and so on, the elevation of alpha-fetoprotein can also be seen. For patients with elevated alpha-fetoprotein found in the examination, they should go to the relevant departments of regular hospitals for consultation, and professional doctors will give relevant diagnosis and treatments according to the patient’s specific situation and the examination results for comprehensive consideration. Patients should not diagnose by themselves with the checklist.
