title: Serum estrogen level in Egyptian breast cancer patients.
abstract: In menstruating 20-29 year old breast cancer patients, the total estrogen level showed a significant increase in the early follicular phase compared to normal healthy subjects. Such a difference was not observed in 30-45 year-old patients. A nonsignificant decrease was observed in the estradiol level of premenopausal breast cancer patients compared to normal healthy subjects. However, in postmenopausal breast cancer patients, the total estrogen level as well as the estradiol level showed a significant increase compared to that of normal healthy subjects.
