癌前病变指某种可以识别的改变,经一段潜伏期后,在该部位发生癌变。现已证实,某些类型的病变,尤其是白斑,续发恶性病变者较多,而不能用偶合来解释。但是,对于此种一系列改变的性质了解甚少,也未证实可发现的癌前病变是普遍现象,事实上或许还并不常见。当然,在癌变前,组织中可能发生某些改变,但是却不一定能够发现,也可能不引起症状。

A precancerous lesion is a identifiable change that occurs after a period of incubation. It has been confirmed that some types of lesions, especially leukoplakia, have more malignant lesions and cannot be explained by coupling. However, little is known about the nature of this series of changes, nor has it been proven that precancerous lesions that are detectable are common, and in fact may not yet be common. Of course, some changes may occur in the tissues before the cancer, but they may not be able to be found or they may not cause symptoms.
