Abstract. In this article, liver tumors, or liver cancer, refer to tumors that arise in the liver tissue. These tumors can be classified as primary liver tumors or metastatic tumors that have spread to the liver from other organs. It provides important information about the pathomorphological characteristics of liver tumors, as well as their developmental stages and cellular structure. Liver cancer is one of the global health problems, and its high mortality rate and difficulties in early detection increase the relevance of this study. The main problems associated with liver tumors include their early detection, the effectiveness of treatment methods, and the difficulties in monitoring tumors in patients. Since many patients have tumors that develop without symptoms in the early stages of liver cancer, it is very difficult to detect it early. According to statistics, approximately 900,000 people die from liver cancer every year. These tumors are often associated with viral hepatitis and alcohol-related diseases, and studies in China also show a high prevalence of liver cancer.
