Bovine lactoferrin (bLF) (80 kDa) has in vitro and in vivo anticancer activity against several types of cancer (Chea et al., 2018; Gibbons et al., 2015; Haney et al., 2012; Li et al., 2017; Luzi et al., 2017; Rocha et al., 2022; Sun et al., 2012; Wolf et al., 2003; Zhang et al., 2015), and it induced a reduction in colorectal cancer polyps, improvement in patient quality of life, and reduction in toxic side effects of chemotherapy drugs (Kozu et al., 2009; Moastafa et al., 2014).
