Cancer is a disease whose progression is driven by a series of accumulating genetic and epigenetic changes influenced by hereditary factors and the somatic environment. These changes result in individual cells acquiring a phenotype that provides those cells with a survival advantage over surrounding normal cells. Our understanding of the processes that occur in malignant transformation is increasing, with many discoveries in cancer cell biology having been made through the study of childhood tumors. The processes involved in oncogenesis and cancer progression will be discussed in this review.
癌症是一种疾病,其进展由一系列累积的遗传和表观遗传变化驱动,这些变化受遗传因素和体细胞环境影响。这些变化导致单个细胞获得一种表型,使这些细胞比周围的正常细胞具有生存优势。我们对恶性转化过程的理解正在不断加深,通过对儿童肿瘤的研究,在癌细胞生物学方面有了许多发现。本综述将讨论肿瘤发生和癌症进展所涉及的过程。
