The importance of IGF-1
What is particularly interesting about the IGF-1 in women is that it is able to product an increase in ovarian cancer in women who are younger than 55, which is normally younger than women develop the condition. Who else may have increased levels with IGF-1? You guessed it - those who have PCOS. So, while causality might not be proven or present in PCOS and ovarian cancer, IGF-1 is more likely to be present in those who have PCOS, which is more likely to cause precipitate ovarian cancer.
