IGF1 and cancer: Interestingly, significant positive genetic correlations were observed between IGF-1 (rg = 8.43%, se = 1.38%, P = 1.10E-09); standing height (rg = 4.32%, se = 1.31%, P = 9.59E-04) and hormone-sensitive cancer that provides a suggestive clue to cancer aetiology wherein an increase in IGF-1 level and height confers a higher risk of hormone-sensitive cancer.
