Cancer can kill us even if one cell gets the wrong mutations (or epimutations), whereas any loss of function in any genes that have nothing to do with cancer are harmless unless and until they have happened to a lot of the cells in a given tissue.

即使一个细胞发生错误的突变（或表突变）而引起癌症，癌症就会杀死我们，然而，任何基因丧失了任何功能但不引起癌症，则是无害的，除非它们已经发生于一个特定组织中的很多细胞。
