One of the most important reasons is that women are starting puberty earlier. In the 1950s, the average age for periods to start was 13 – now it’s 11. There are theories about why this is – increasing obesity rates in children and dietary influences on hormone levels, for instance – but the truth is, it’s not really known why. We do know that the younger a girl is when they start, the longer her body is exposed to higher levels of estrogen. So women who start menstruatng early should be particularly a focus of the importance of learning early to examine their breasts properly and regularly which typically is not the practice. #breastcancerinyoungwomen #breastcancertreatment
