Alpha-fetoprotein, also known as AFP, reflects the function of the liver and whether there are any diseases present. The accuracy and specificity of alpha-fetoprotein in diagnosing liver cancer are relatively high. In non-pregnant individuals, whether male or female, an elevated alpha-fetoprotein level should raise suspicions of liver disease, and it is advisable to promptly undergo ultrasound or CT scans to determine the presence of liver cancer or other liver diseases. However, during pregnancy, as the fetus grows and develops, a certain amount of alpha-fetoprotein is released. Therefore, when testing the blood of pregnant women, an increase in alpha-fetoprotein is observed. This condition is a physiological change and does not indicate the occurrence of liver diseases such as liver cancer in women. Thus, alpha-fetoprotein can serve as an auxiliary method for diagnosing liver cancer, but only in non-pregnant individuals.
