We do know that metastasis is a very inefficient process, with most cancer cells that escape into the blood stream failing to form metastatic tumors in distant organs. Recent studies – from both the laboratory and the clinic – suggest that many cancer cells that leave the primary tumor may lodge themselves in new organs and go into a dormant state.
我们都知道转移是一个非常缓慢的过程，因为游离到血液中的大多数癌细胞都无法在其他器官中形成转移瘤。但同时来自来自实验室和临床的最新研究却发现许多游离出原发瘤的癌细胞都能寄居在其他器官中并进入休眠状态。
