Hepatocellular carcinoma (HCC) occurs uncommonly in the United States and Western Europe, but is a relatively frequent neoplasm in sub-Saharan Africa, China, and the Far East. Environmental factors appear to determine the geographic clustering of the disease and to cause different spectrums of the disease in the high-incidence and low-incidence areas of the world.
肝细胞癌（HCC）在美国和西欧并不常见，但在撒哈拉以南非洲、中国和远东地区却是一种相对常见的肿瘤。环境因素似乎决定了该疾病的地理聚集性，并在世界高发病率和低发病率地区导致不同类型的疾病。
