VEGFC and neoplasm: The lymphatic vasculature is critical to immunity with one of its major roles being the trafficking of immune cells.31 High VEGF‐C expression in experimental mouse models has previously been found to promote lymphatic vessel enlargement with lymphatic endothelial cell proliferation.32, 33 Recently, several studies have found that dilated lymphatic vessels exhibit impaired transport capacity,33, 34 making immune cells difficult to transport into the tumor.
