Yet lessons learned in dealing with exotic species, combined with recent mathematical models of the evolutionary dynamics of tumors, indicate that eradicating most cancers may be impossible. Trying to do so, moreover, could worsen the problem.
但人们以往与异常物种打交道的经验和最近有关肿瘤进化动力学的数学模型告诉我们，彻底治愈绝大多数癌症可能是不现实的目标。不仅如此，这样做还有可能使问题进一步恶化。
