OBJECTIVE Evaluation of changes in mammographic and ultrasound image of the breast in female patients undergoing estrogen hormonal replacement therapy (ERT). MATERIAL AND METHODS 126 women with surgical menopause in case of benign disease using ERT and a control group of 100 women in menopause with no hormonal replacement therapy were selected for the study. Changes in the mammographic image ...

BACKGROUND & OBJECTIVES Mammographic screening is an effective tool for the early detection of breast cancer. Hormone replacement therapy (HRT) has been shown to increase mammographic density and thus may hinder early detection of small tumours. We undertook this study to determine and compare the frequency and degree of change in mammographic density in postmenopausal women in HRT using two di...

PURPOSE Women with a BRCA1 mutation (BRCA1(mut)) need risk reduction options beyond mastectomy and oophorectomy. We evaluated the efficacy, safety, and tolerability of hormonal chemoprevention with a gonadotropin-releasing hormone agonist (GnRHA) with low-dose add-back steroids in BRCA1(mut) carriers. EXPERIMENTAL DESIGN The 12-month open label clinical trial used the GnRHA deslorelin, ultra-...

INTRODUCTION Mammographic density, the white radiolucent part of a mammogram, is a marker of breast cancer risk and mammographic sensitivity. There are several means of measuring mammographic density, among which are area-based and volumetric-based approaches. Current volumetric methods use only unprocessed, raw mammograms, which is a problematic restriction since such raw mammograms are normal...

OBJECTIVE Hormone therapy use has been positively associated with mammographic density in several studies. However, few studies have examined the association between endogenous hormone levels and mammographic density. Therefore, we evaluated the relationship of endogenous sex hormones, insulin-like growth factor (IGF), and lipids with mammographic density in 88 overweight, postmenopausal women ...

Breast cancer incidence rates in the United States are substantially lower among Asian-American women than among White or African-American women. The authors determined whether mammographic density reflects these ethnic differences by evaluating mammograms from 442 White, African-American, and Asian-American women without breast cancer who served as controls in one of two population-based, brea...

BACKGROUND Mammographic density is a strong risk factor for breast cancer. It is unknown whether there are different causes of variation in mammographic density at different ages. METHODS Mammograms and questionnaires were obtained on average 8 years apart from 327 Australian female twin pairs (204 monozygous and 123 dizygous). Mammographic dense area and percentage dense area were measured u...

AIMS Certain phytoestrogens, such as lignans, may protect against developing breast cancer. Enterolactone is a lignan metabolite produced by the intestinal flora from dietary precursors such as whole grains, vegetables, and fruits. Enterolactone has been shown to have weak estrogenic and antiestrogenic properties. We decided to examine the association between plasma levels of enterolactone and ...

BACKGROUND In premenopausal women, the sensitivity of screening mammography for detecting breast cancer has been reported to be greater in the follicular phase than in the luteal phase of the menstrual cycle, which may be due to differences in mammographic density. To examine this possible effect, we compared mammographic density in premenopausal women who had mammograms at different phases of ...
