Liver cirrhosis is a common kind of chronic liver diseases, with the development of diseases; some patients may gradually develop precancerous lesions, or even progress to hepatocellular carcinoma (HCC). Precancerous lesions of the liver mainly include dysplastic foci (DF) and dysplastic nodules (DN), and most of it occurs on the basis of liver cirrhosis.
