Serum alpha-fetoprotein is a special protein produced by fetal stem cells and is a normal component of fetal serum. Hepatocellular carcinoma cells can synthesize serum alpha-fetoprotein, and serum alpha-fetoprotein is significantly elevated in the serum of patients with primary hepatocellular carcinoma. If there is acute hepatitis, chronic hepatitis or cirrhosis, serum alpha-fetoprotein can also be seen to be elevated, but the degree of elevation is not as high as that of primary hepatocellular carcinoma. Some other malignant tumors that metastasize to the liver can also lead to elevated serum alpha-fetoprotein. However, if the serum alpha-fetoprotein is simply elevated, it is not necessarily liver cancer, and should be combined with ultrasound, liver function and other tests to make a comprehensive judgment. If serum alpha-fetoprotein is high, it is necessary to actively carry out examination and review. You can eat more fruits containing vitamin C, because vitamin C has the function of anti-cancer and anti-cancer. Normally, you should not drink alcohol, work and rest regularly, work pressure should not be too much, and eat a light diet.
