The central role of DNA injury and epigenetic defects in DNA repair service genes in carcinogenesis The classical view of cancer is actually a set of conditions pushed by progressive genetic abnormalities that come with mutations in tumor-suppressor genes and oncogenes, and in chromosomal abnormalities. A job for epigenetic alterations was discovered in the early 21st century.[103]
体重减轻。癌症和癌症治疗可能导致体重减轻。癌症肿瘤会夺取正常细胞的营养。这通常不受摄入多少卡路里或吃哪类食物的影响，而且难以治疗。在大多数情况下，通过管子将人工营养输入胃或静脉中并不能帮助改变体重减轻的状况。

The crucial element innovation below lies in the use of protein cage nanoparticle-based units.
