Estrogen is responsible for the mediation of puberty in females, and in girls with delayed puberty due to hypogonadism (low-functioning gonads, which can result in low sex hormone levels) such as in Turner syndrome, estradiol is used to induce the development of and maintain female secondary sexual characteristics such as breasts, wide hips ...
Rates of breast cancer in women under 50 have increased more than 15% in the last two decades, a rise that is almost entirely driven by an increase in estrogen receptor-positive breast cancer (ER+ ...
