Interestingly, it is reported that body height associated with GH and IGF1 levels also related to cancer risk, individuals taller than 175 cm have a 20% higher risk of developing prostate cancer than those shorter than 160 cm, a 20–60% higher risk of developing colorectal cancer, and have 22% higher risk of developing breast cancer (Gunnell et al., 2001; Lango Allen et al., 2010). This evidence concerns the gene GH1 and cancer.
