Breast volume and body composition were measured in 45 adult females to determine the contribution of breast weight and breast volume to total body fat. Plaster casts were filled with sand of known density to obtain breast volume. Breast weight was computed as breast volume times its density. The correlation between total breast volume and percent body fat was r = .40. Breast weight (mean = 484...

The proportion of adults who are obese has increased dramatically in the United States over the last 30 years. Obesity has been linked to an increased risk of developing a number of malignancies, including postmenopausal breast cancer. Evidence also suggests that obesity at the time of breast cancer diagnosis is linked to an increased risk of breast cancer-specific and overall mortality in both...

INTRODUCTION Breast cancer survival rates are lower for African American women than for white women. Obesity, high-fat diets, and lack of regular physical activity increase risk for breast cancer recurrence, comorbid conditions, and premature death. Eighty-two percent of African American women are overweight or obese, partly because of unhealthy eating and exercise patterns. Although successful...

background: the aim of this study was to investigate the effects of exercise training on maximum aerobic capacity, resting heart rate (rhr), blood pressure and anthropometric variables of postmenopausal women with breast cancer. methods : twenty nine women with breast cancer who received surgery, chemotherapy and radiotherapy with current hormone therapy were divided into two groups; interventi...

The study evaluated the body weight during growth (BWG), body weight at slaughter (BWS), breast meat yield (BMYg), percent breast meat yield (BMY) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. Two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...

Excess adiposity and hormone replacement therapy (HRT) are important contributors to postmenopausal breast cancer risk. HRT has been shown to modify the association between body weight and breast cancer risk, although few studies are sufficiently large to examine the risk of breast cancer associated with body mass index (BMI) and weight gain separately among current HRT users and nonusers. This...

CONTEXT The relationship between body size and breast cancer still remains controversial in considering menopausal status. OBJECTIVE To evaluate the association of height, weight and weight changes with breast cancer in the city of Rio de Janeiro, Brazil. DESIGN Case-control study. SETTING National Cancer Institute (INCA), Rio de Janeiro, Brazil, and State University of Rio de Janeiro (UE...

CONTEXT Endogenous hormones are a primary cause of breast cancer. Adiposity affects circulating hormones, particularly in postmenopausal women, and may be a modifiable risk factor for breast cancer. OBJECTIVE To assess the associations of adult weight change since age 18 years and since menopause with the risk of breast cancer among postmenopausal women. DESIGN, SETTING, AND PARTICIPANTS Pr...

BACKGROUND Pregnancy has a short-term risk-increasing effect on breast cancer that may be attributed to growth-promoting effects of pregnancy hormones on prevalent but undetected tumors. Results of two previous studies suggested that placental weight may be positively associated with breast cancer risk. METHODS In a cohort of 338,051 women followed from 1999 to 2008, on the basis of data link...
