Concept and research progress of precancerous lesions / 中华肝脏病杂志

ABSTRACT

The concept of precancerous lesions was first proposed in 1948. With the progress of animal models, genetic analysis, clinical pathology, and imaging studies, precancerous lesions have received much attention, and the reversion of precancerous lesions has also attracted widespread concern. Precancerous lesions are not cancers, nor are they early stages of cancer. They are qualitatively different from cancers; precancerous lesions are only a small part of them which may develop into cancer. It is of great significance to pay attention to the management of diagnosis and treatment of precancerous lesions for the prevention, treatment and maintenance of people's physical and mental health.
