A bibliographical review of social differences in morbidity and mortality is presented. The data concerns France, Great Britain and U.S.A., only for recent years, and come from large surveys, health examinations, or morbidity or mortality registers. The social class variable may be the educational level, or a professional classification. Different aspects of mortality and morbidity are examined: cancer, cardio-vascular diseases, respiratory diseases, musculo-skeletal diseases, digestive diseases, obesity and diabetes, accidents, mental illnesses; acute and minor illnesses, and unusual illnesses, are no studied. For almost all the diseases in this review, the risk is greater in the lowest socioeconomic class.

A comprehensive review of what was known of the epidemiology of breast cancer as of the early 1970s was published by MacMahon et al. in 1973. This review covers the major aspects of the epidemiology of breast cancer included in the 1973 review and, additionally, emphasizes recently reported work. Attention is directed to the following: magnitude of the problem in the U.S.; demographic characteristics of breast cancer cases; international variation; laterality of breast cancer; reproductive variables; benign breast diseases; multiple primary cancers involving the breast and other sites; familial aggregation and genetics; endogenous hormones (estrogens, progesterone, prolactin, androgens, and thyroid); exogenous estrogens; diet; body build; radiation; exposure to radiation in screening for breast cancer; mammographic parenchymal patterns; viruses; other exposures of current interest (reserpine, hair dyes); and breast cancer in males. The high incidence and mortality rates and the detrimental impact on the quality of life of those affected indicate that breast cancer in the U.S. continues to be a serious problem for women. An annual age-adjusted incidence rate of 84.9/100,000 women was reported for the 1973-1976 years; the annual age-adjusted mortality rate among women in the U.S. was 27.7/100,000 over this same time period. From these figures, it may be estimated that each year in the U.S. almost 100,000 cases of breast cancer are diagnosed, and over 30,000 deaths occur. Age specific incidence rates increase rapidly with age until about 45-50 years of age, after which they continue to increase but at a slower rate. In addition to age, a few other risk factors, including a history of bilateral premenopausal breast cancer in a 1st degree relative, a history of breast cancer in the contralateral breast, and residence from an early age in North America compared to Asia, are associated with large relative risks. Other risk factors, including whether or not an oophorectomy has been performed, age at 1st birth, a history of fibrocystic disease, previous exposure to high levels of radiation in the chest, socioeconomic status, obesity, and a previous cancer in the ovary or endometrium are associated with relative risks of at least 2 but less than 4-fold. Finally, age at menarche, age at menopause, marital status, place of residence, and the white compared to the black race are associated with small but real differentials in risk.

The incidence of ovarian cancer in Rochester, Minnesota over the 40-year period 1935 through 1974 was determined; and risk factors for epithelial ovarian cancer occurring in Rochester from 1945 to 1974 were examined in 116 patients and 464 controls. Among the characteristics studied, only nulliparity was found to be a significant risk factor--relative risk 1.8. Other suspected risk factors--including hypertension, obesity, age at menopause, prior therapeutic pelvic radiation, and prior exposure to exogenous estrogen--were found not to differ significantly between patients and controls. The ovarian cancer patients were found to have a significantly lower frequency of prior hysterectomy and of unilateral oophorectomy than the control group. Thus out data show that hysterectomy, even when one or both ovaries are preserved, is associated with a lower risk of subsequent ovarian cancer.

An optimal diet cannot yet be defined. If we knew what an optimal diet was, additional research in nutrition would not be necessary. There is abundant evidence, however, that the usual American diet is not optimal and adequate reason to recommend modification. Current dietary recommendations were developed to prevent the occurrence of nutritional deficiency disease in the 1930's and 1940's. They have been largely successful. They were made, however, before any knowledge was available about the effects of diet upon chronic disease which now represent the primary health problems of the United States. Large amounts of data are available indicating the kids of recommendations which should be made to control hypercholesterolemia--a primary risk factor of coronary artery disease. These kinds of data together with less information upon diet and cancer, hypertension, obesity, diabetes, etc. lead to sensible and consistent dietary recommendations to moderate the dietary practices of most Americans.

Correlations between obesity and prognosis of operated cancer of the breast have not been investigated until now. In 491 patients operated upon by radical mastectomy (1968 to 1972) it can be demonstrated that in patients in whom the weight of the resected breast is above 1100 g the survival rates are more unfavourable than in other cases. As to tumor size and invasion of lymphnodes the distribution in the group with "heavy breasts" is more unfavourable than in the other groups. The causes of the differences in survival may be attributed to worsened conditions for detection of cancer in cases with large breasts as well as to alterations of hormone production and metabolism in connection with nutritional factors.

The jet-wash technique is an efficient method for diagnosing the endometrium carcinoma. Among 750 women we detected 50 endometrium carcinomata all of which were diagnosed by the jet-wash method. Wrongly positive findings do not exist in our series of examinations. Of the pre-stages of the endometrium carcinoma, such as adenomatous hyperplasia and adenocarcinoma in situ, however, only scarcely 50 per cent of all cases were diagnosed. The jet-wash method is also suited for outpatient clinics. Thus, patients with risk-factors for the endometrium carcinoma might be controlled annually once in outpatient clinics in addition to the usual cancer prophylactic examinations. Above all, we consider 1. patients suffering from bleeding anomalies as from the 40th year of age, 2. patients free from any symptoms, but suffering from obesity, hypertension and diabetes mellitus, 3. patients with an increased narcosis risk, 4. patients of the perimeno-pause prior to an estrogen treatment and 5. cancer post-care patients suffering from a primarily radiated endometrium carcinoma. The direct smears and the cytocentrifuge preparations can be diagnosed right on the day of examination. The thrombin cell block technique requires more work for a cytological laboratory. For a histological laboratory it might not mean any additional essential burden.

A number of recent studies have shown an association between breast-cancer risk and height, weight and dietary habits, especially fat consumption. In the present study, height and weight were determined for 179 consecutive, unselected, breast-cancer patients and age-matched controls selected from a computerized population register. Height and weight for these two groups were compared, including two different indices for overweight (Quetelet's index and Broca's index). Comparisons were repeated after subdivision into pre- and postmenopausal women. In all calculations, the mean values of patients and controls were very similar and without significant difference. It therefore seems improbable that increased height and weight or obesity constitute risk factors for breast cancer. Earlier studies may have shown differences as the result of selection mechanisms not present in this study.

The existence of dietary risk factors in breast cancer of post-menopausal women is a recent, and yet unproven hypothesis. A French survey made possible by the cooperation of general surgeons and radiotherapists practising in private clinics is currently in progress in a number of metropolitan departments. A preliminary evaluation of the first 654 questionnaires has proved entirely negative. There was no difference between women with breast cancer and a population of age-matched controls with regard to weight, height or the various traditionnal indices of obesity. However, the number of patients studied is too small to allow this hypothesis to be still rejected.

Mean, age-standardized breast-cancer mortality rates for women of 41 countries, during 1970-71, were closely correlated with diet for 1964-66. Partial correlation analysis indicated that breast-cancer rates were positively correlated with total fat, animal protein and animal calories, independently of other components of diet. These 3 components were correlated with one another so closely that it was not possible, with available data, to say whether any one was associated with breast cancer independently of the other 2. In addition to, and independently of, these correlations, breast cancer was associated with consumption of refined sugar.Breast-cancer mortality rates at 50-54 years during 1964-67 for 26 countries were closely correlated with childbearing, expressed as mean family size for women aged 45-49 years in 1960-61. However, this correlation was not independent of the correlations with diet, and it was concluded that variation of breast-cancer rates between countries arose predominantly from differences in diet. The variation of breast-cancer risk with childbearing, observed in clinial studies, seemed best regarded as a second gradient of risk, seen more readily as variation of breast-cancer rates within a population, where differences in diet would be relatively small.The physiological basis for the association between breast cancer and diet was not clear. The dietary associations did not correlate in an obvious way with height, obesity and oestrogen levels, factors observed in clinical studies to influence risk of breast cancer. That the observed statistical associations were real was supported by published findings on effects of diet on mammary cancer in experimental animals, as well as the lower rates of breast cancer amongst vegetarians.

Previous studies have reported high rates of gallbladder disease and gallbladder cancer among all American Indians. Data from the New Mexico Tumor Registry confirm these findings, specifically showing high rates for New Mexico's American Indians, as well as for the state's Spanish population. This review explores several risk factors, including parity, obesity, age, cholesterol level, and genetic factors. From the available evidence, genetic factors appear to be the most important, with parity a contributing factor.
