In this sobering work, a respected medical writer and researcher warns women not to be too hasty in embracing estrogen replacement therapy, which so many doctors are now recommending with great enthusiasm. A careful, cautionary book that will stir controversy--and may save lives.

This book provides a comprehensive and up-to-date review of the relationship between obesity and cancer. It opens with a global perspective on obesity and cancer incidence, followed by in-depth discussions of those cancers for which we have sufficient evidence of a causal relationship with obesity. It addresses topics such as the effects of obesity on cancer incidence and cancer survival, the effects of weight gain and weight loss in adulthood on cancer risk, the effects of childhood and adolescent obesity, and the role of body fat distribution in cancer risk. Individual chapters discuss potential pathways for the observed associations and explore possible mechanisms from both an epidemiological and an experimental perspective. It concludes with a population perspective on the cancer risk that is attributable to obesity and is thus potentially avoidable. This book is of particular value to researchers and epidemiologists and is also of interest to public health workers and clinicians.

A compelling, “fascinating” (Robert Cialdini) defense of hormone replacement therapy, exposing the faulty science behind its fall from prominence and giving women the evidence they need to make informed decisions about their health. Now fully revised and updated. "Estrogen Matters was my antidote to the misinformation surrounding menopause. This book should be the bible for every single person going through menopause.”―Naomi Watts For years, hormone replacement therapy (HRT) was the medically approved way to alleviate menopausal symptoms (ranging from hot flushes to brain fog) and reduce the risk of heart disease, Alzheimer's, and osteoporosis. But when a large study by the Women's Health Initiative (WHI) announced, with national fanfare, that women taking HRT had an increased risk of breast cancer, women were scared off, and the treatment was abandoned. Now, Dr. Bluming, a medical oncologist, and Dr. Tavris, a social psychologist, reveal the true story of the WHI’s efforts to distort their data to exaggerate unsupported claims of estrogen’s harms. Important updates in this edition include: Evidence that demolishes the WHI’s claim that HRT causes breast cancer. A list of the WHI’s retractions of their original scare stories. Updated findings on estrogen’s benefits on heart, brain, bones, and longevity. A critical review of the alternative products and medications being marketed to treat symptoms of menopause. A sobering and revelatory read, Estrogen Matters sets the record straight on estrogen’s benefits, providing a light to guide women through this inevitable phase of life.

This book covers a topic of considerable current interest and presents many of the most significant research findings available to date. Workers at the forefront of research on hormone replacement therapy and the implications for the risk of breast cancer were invited to attend a special Conference at the Royal Society of Medicine in London in September, 1991, where the latest data were presented to a distinguished audience and the implications of this research were discussed. The volume reviews various aspects of HRT and breast cancer, the physiology of the menopause, the current use of HRT in practice, osteoporosis and epidemiology and presents results from a range of European, American and Australian studies on the role of breast cancer and HRT, finishing with an overview of benefits, use and cost-effectiveness and a general summary. The book represents a definitive statement of current knowledge in this field and an informative update on the implications of recent research. It will be a valuable addition of special significance to the libraries of all those concerned with hormone replacement therapy and the study of breast cancer.

At least 10.7 million American women use oral contraceptives (OCs). The potential connection with breast cancer has caused concern among these OC users and uncertainty among many of their physicians. This new volume offers the most up-to-date information available on this critical topic. While the best available knowledge does not support any fundamental change in clinical practice with respect to the use of OCs, this book offers specific recommendations for more research to fully resolve the relationship between OCs and breast cancer. Noting consumer confusion, the volume includes a concise summary of benefits, risks, and other practical information for contraceptive users and their doctors. The volume presents current data on changes in patterns of OC use, differences in risk at different ages, the benefits of OCs, and more. Oral Contraceptives and Breast Cancer will be important reading for obstetricians/gynecologists and other health professionals, their patients who use OCs, contraceptive manufacturers, women's health advocates, policymakers, and researchers.

Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal estrogen therapy, and post-menopausal estrogen-progestogen therapy. Although the carcinogenicity of these preparations has been extensively investigated, the book stresses the many complex methodological issues that must be considered when interpreting findings and weighing results. Evidence of an association between use of these preparations and positive effects on health, including a reduced risk of some cancers, is also critically assessed. The first and most extensive monograph evaluates evidence of an association between the use of combined oral contraceptives and cancer at nine sites. Concerning breast cancer, the evaluation concludes that, even if the association is causal, the excess risk for breast cancer associated with patterns of use that are typical today is very small. Studies of predominantly high-dose preparations found an increased risk of hepatocellular carcinoma in the absence of hepatitis viruses. Citing these findings, the evaluation concludes that there is sufficient evidence in humans for the carcinogenicity of combined oral contraceptives. The evaluation also found sufficient evidence for the carcinogenicity of some, but not all, combined preparations in animals. Combined oral contraceptives were classified as carcinogenic to humans. The evaluation also cites conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium. Progestogen-only contraceptives are evaluated in the second monograph, which considers the association with cancer at six sites. The evaluation found no evidence of an increased risk for breast cancer. Although the evaluation found sufficient evidence in animals for the carcinogenicity of medroxyprogesterone acetate, evidence for the carcinogenicity of progestogen-only contraceptives in humans was judged inadequate. Progestogen-only contraceptives were classified as possibly carcinogenic to humans. The third monograph, on post-menopausal estrogen therapy, considers evidence of an association with cancer at eight sites. Findings from a large number of epidemiological studies indicate a small increase in the risk of breast cancer in women who have used these preparations for five years or more. Studies consistently show an association between use of post-menopausal estrogen therapy and an increased risk for endometrial cancer. Data on the association with other cancers were either inconclusive or suggested no effect on risk. The evaluation concludes that post-menopausal estrogen therapy is carcinogenic to humans. The final monograph evaluates the association between the use of post-menopausal estrogen-progestogen therapy and cancer at four sites. The evaluation of limited data on breast cancer found an increased relative risk observed with long-term use. Data were judged insufficient to assess the effects of past use and of different progestogen compounds, doses, and treatment schedules. For endometrial cancer, the evaluation found an increase in risk relative to non-users when the progestogen was added to the cycle for 10 days or fewer. Post-menopausal estrogen-progestogen therapy was classified as possibly carcinogenic to humans. Concerning post-menopausal therapy in general, the book notes that evidence of carcinogenic risks must be placed in perspective of potential benefits. The prevention of osteoporotic fractures is cited as the best-established benefit. Evidence also suggests that estrogen prevents heart disease and may prevent memory loss and dementia.
