TL;DR: Postmenopausal vegetarian women were found to have lower urinary levels of estriol and total estrogens, lower plasma prolactin levels, and higher plasma sex hormone-binding globulin levels, which were also higher in vegetarians than in nonvegetarians.
Abstract: In comparison with matched nonvegetarian women, postmenopausal vegetarian women were found to have lower urinary levels of estriol and total estrogens, lower plasma prolactin levels, and higher plasma sex hormone-binding globulin (SHBG) levels. These differences were not explained by differences in body weight or obesity. Plasma SHBG levels were highly correlated with plasma high-density lipoprotein cholesterol levels, which were also higher in vegetarians than in nonvegetarians. These hormonal differences may explain the lower rates of endometrial and possibly breast cancer that have been observed previously in vegetarian women.

TL;DR: Concentrations of estrone and estradiol tended to be higher in the daughters of breast cancer patients than in the controls; total estrogens were elevated in both phases of the menstrual cycle and significantly so in the luteal phase.
Abstract: Urine levels of three major estrogens and of pregnanediol were measured for 76 nulliparous daughters of breast cancer patients and for 115 control women of similar age and parity. Concentrations of estrone and estradiol tended to be higher in the daughters of breast cancer patients than in the controls; total estrogens were elevated in both phases than in the controls; total estrogens were elevated in both phases of the menstrual cycle and significantly so in the luteal phase. There was little difference between the daughters and the controls in estriol ratios--the ratios of the concentration of estriol to the sum of the concentrations of estrone and estradiol. Pregnanediol levels were higher in the daughters than in the controls.
