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.

Annotation Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal oestrogen therapy, and post-menopausal oestrogen-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.

Oral contraceptives for family planning worldwide have revolutionized the reproductive lives of millions of women since their introduction in the 1960s. Later on, a variety of side-effects including cardiovascular diseases was recognized. In response to these concerns, new generations of combined oral contraceptives were developed that featured lower dose of estrogen and newer, more potent progestogens. The effectiveness and ease of use of combined hormonal contraceptives suggest that they will continue to be used to a significant extent in the future. This ninety-first volume of IARC Monograp.

An information guide to information on the subject of menopause.

Drawing together many of the world's foremost experts, this book provides clear and specific guidance about the prescription of hormone replacement therapy. It covers prescribing for patients with a wide range of pre-existing diseases. In each instance, expert advice is given with reference to the latest published research. There is also an overview of other key issues affecting the choice of therapy.

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.
