It is well known that the tumor mainly transfers through the lymphatic vessels of the tumor .The current studies main-ly focus on the mechanism of metastasis , hoping to uncover the lymph node metastasis through investigating generation of lymphatic ves -sels and remodeling of tumor lymphatic vessels .Lymph node metastasis is directly related to and prognosis and the quality of life of cancer patients , and how to block the corresponding signaling pathways to prevent tumor lymphangiogenesis becomes the research fo -cus.This paper reviews the lymphangiogenesis and lymphatic vessel remodeling .
