The role of the lymphatic system in the metastasis of cancers is to provide a pathway for cancer cells to enter lymphatic vessels and travel to other parts of the body, where they can form secondary tumors. Once cancer cells enter the lymphatic system, they can travel to lymph nodes and beyond, leading to the spread of cancer. Therefore, the lymphatic system can promote the metastasis of cancer.
