Evidence on dietary risk factors for ovarian cancer is inconsistent, but some studies have suggested positive associations with dietary fat, lactose, and cholesterol and negative associations with green and yellow vegetable intake. By using information from the Iowa Women's Health Study, the authors investigated the association of epithelial ovarian cancer(More)
Objective: Mammographically defined percent breast density is an important risk factor for breast cancer, but the epidemiology of this trait is poorly understood. Although several studies have investigated the associations between reproductive factors and density, few data are available on the associations of breast density and waist-to-hip ratio (WHR),(More)
BACKGROUND Recent clinical guidelines on the health risks of obesity use body mass index (BMI; calculated as weight in kilograms divided by the square of height in meters) and waist circumference, but the waist-hip ratio may provide independent information. METHODS To assess the joint and relative associations of BMI, waist circumference, and waist-hip(More)
OBJECTIVE Previous epidemiological studies have suggested that use of aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with reduced risk of breast cancer, but some studies have been limited in their ability to separate the effects of aspirin from other NSAIDs or to account for breast cancer risk factors. METHODS We examined(More)
BACKGROUND We evaluated prospectively the association of smoking and other potential risk factors with bladder carcinoma incidence in postmenopausal women. METHODS A total of 37,459 women participating in the Iowa Women's Health Study completed baseline questionnaires in 1986 and were followed 13 years for bladder carcinoma incidence (n = 112). RESULTS(More)
Epidemiologic studies of pancreatic cancer risk have reported null or nonsignificant positive associations for obesity, while associations for height have been null. Waist and hip circumference have been evaluated infrequently. A pooled analysis of 14 cohort studies on 846,340 individuals was conducted; 2,135 individuals were diagnosed with pancreatic(More)
Polymorphic arylamine N-acetyltransferase 2 (NAT2) status varies widely between individuals and ethnic groups and has been associated with susceptibility to several cancers. Few studies have reported the distribution of NAT2 status for Caucasian-American populations or evaluated the concordance between methods of assessment for cancer cases and controls. In(More)
Many epidemiologic studies, although not all, have shown an inverse relation between non-steroidal anti-inflammatory drug (NSAID) use and risk of incident breast cancer, but the possible influence of NSAID use on breast cancer survival has not been evaluated. We examined the association between self-reported NSAID use and survival after invasive breast(More)
BACKGROUND Compared with the general population, carriers of germline mutations in RB1 who survive retinoblastoma (i.e., hereditary retinoblastoma survivors) are at increased risk of early-onset second cancers, particularly sarcomas, brain tumors, and melanoma. However, their risks for the epithelial cancers that commonly occur after age 50 years are not(More)
PURPOSE Endometrial cancers have long been divided into estrogen-dependent type I and the less common clinically aggressive estrogen-independent type II. Little is known about risk factors for type II tumors because most studies lack sufficient cases to study these much less common tumors separately. We examined whether so-called classical endometrial(More)
