The absence of carcinogenic effects demonstrated in any of the clinical or animal trials of exogenous ghrelin or ghrelin-receptor agonist therapy is also consistent with the considerable clinical data showing no association of GH therapy with increased risk of cancer in children (Allen et al. 1997, Sävendahl et al. 2012, Patterson et al. 2014, Raman et al. 2015) or in adults (Olsson et al. 2012, Hartman et al. 2013, Brignardello et al. 2015, Child et al. 2015, Stochholm & Johannsson 2015). Here, GHRL is linked to cancer.
