CCR7 is further associated with a wide variety of cancers (Balkwill, 2012, Günther et al., 2005, Müller et al., 2001, Shields et al., 2007), where chemotactic trafficking allows cancer cells to spread by lymph node metastasis (Cunningham et al., 2010, Wiley et al., 2001, Zlotnik et al., 2011). Here, CCR7 is linked to cancer.
