AbstractEvidence that diet is associated with breast cancer risk is inconsistent. Most of the studies have focused on risks associated with specific foods and nutrients, rather than overall diet. In this study, we aimed to evaluate the association between dietary patterns and breast cancer risk in Japanese women. A total of 49 552 Japanese women were followed-up from 1995 to 1998 (5-year follow-up survey) until the end of 2012 for an average of 14·6 years. During 725 534 person-years of follow-up, 718 cases of breast cancer were identified. We identified three dietary patterns (prudent, westernised and traditional Japanese). The westernised dietary pattern was associated with a 32 % increase in breast cancer risk (hazard ratios (HR) 1·32; 95 % CI 1·03, 1·70; Ptrend=0·04). In particular, subjects with extreme intake of the westernised diet (quintile (Q) Q5_5th) had an 83 % increase in risk of breast cancer in contrast to those in the lowest Q1 (HR 1·83; 95 % CI 1·25, 2·68; Ptrend=0·01). In analyses stratified by menopausal status, postmenopausal subjects in the highest quintile of the westernised dietary pattern had a 29 % increased risk of breast cancer (HR 1·29; 95 % CI 0·99, 1·76; Ptrend=0·04). With regard to hormone receptor status, the westernised dietary pattern was associated with an increased risk of oestrogen receptor-positive/progesterone receptor-positivetumours (HR 2·49; 95 % CI 1·40, 4·43; Ptrend<0·01). The other dietary patterns were not associated with the risk of breast cancer in Japanese women. A westernised dietary pattern is associated with an increased risk of breast cancer in Japanese women.

Abstract Background: There have been inconsistencies in the evidence for a role of dietary risk factors in the development of breast cancer. In this study, we used a large-scale cohort (Korean Cancer Prevention Study-II [KCPS-II]) to examine the association between dietary patterns and breast cancer risk in Korean women.Methods: The dietary patterns of 14,807 women from the KCPS-II were derived by factor analysis and 135 cases of breast cancer were diagnosed during the follow-up period. Cox proportional models were used to estimate the hazard ratios (HR) and 95% confidence intervals (CI) for the risk of breast cancer. Results: The following three major dietary factors were identified: “Korean dietary pattern” (high intake of Kimchi, vegetables, and rice); “Sweet dietary pattern” (high intake of soda and sugar); and “Western-like dietary pattern” (high intake of dairy products, eggs, oil, fruits, and bread). After adjusting for potential confounders, neither the Korean (HR for the highest compared with the lowest tertile, 1.04; 95% CI 0.53−2.06) nor the Sweet dietary patterns were associated with the risk of breast cancer. In contrast, the Western-like dietary pattern was found to be significantly associated with an increased risk of breast cancer with an HR (95% CI) of 1.01 (0.65−1.60) for the second tertile and 1.61 (1.04−2.50) for the third tertile as compared with the lowest tertile. After stratifying by menopausal status, these effects were only statistically significant among premenopausal women for the third tertile, compared with those in the bottom tertile (HR 1.69; 95% CI 1.06−2.68; p = 0.028). No significant association was observed between the Korean or Sweet dietary pattern and breast cancer among either pre- or postmenopausal women.Conclusions: Our findings revealed that a greater consumption of a Western-like diet was associated with an increased breast cancer risk and consequently offer a potential prevention strategy for Korean women.

Alcohol intake is associated with the risk of breast cancer. Different patterns of alcohol-drinking may have different effects on breast cancer even when keeping constant the total amount of alcohol consumed. We aimed to assess the association between binge drinking and breast cancer risk. The SUN Project is a Spanish dynamic prospective cohort of university graduates initiated in 1999. In the 556-item lifestyle baseline questionnaire a validated food-frequency questionnaire was embedded. Participants completed biennial follow-up questionnaires. Cox regression models were used to estimate the hazard ratio (HR) for breast cancer associated with the exposure to binge drinking. A stratified analysis was performed according to menopausal status. We included 9577 women (mean age = 34 years, SD = 10 years), with a median follow-up of 11.8 years. Among 104,932 women-years of follow-up, we confirmed 88 incident cases of breast cancer. Women in the binge drinking group showed a higher risk of breast cancer (HR = 1.76; 95% CI: 1.03–2.99) compared to women in the non-binge drinking category. In the stratified analysis, a 2-fold higher risk for premenopausal breast cancer was associated with binge drinking habit (HR = 2.06; 95% CI: 1.11–3.82). This study adds new evidence on the association of binge drinking with breast cancer risk.

ObjectiveThe association between thyroid disease and breast cancer risk remains unclear. We, therefore examined the association between hypothyroidism, hyperthyroidism and breast cancer risk.DesignThis was a population-based cohort study.MethodsUsing nationwide registries, we identified all women in Denmark with a first-time hospital diagnosis of hypothyroidism or hyperthyroidism, 1978–2013. We estimated the excess risk of breast cancer among patients with hypothyroidism or hyperthyroidism compared with the expected risk in the general population, using standardized incidence ratios (SIRs) as a measure of risk ratio. Breast cancer diagnoses in the first 12 months following diagnosis of thyroid disease were excluded from the calculations to avoid diagnostic work-up bias.ResultsWe included 61 873 women diagnosed with hypothyroidism and 80 343 women diagnosed with hyperthyroidism. Median follow-up time was 4.9 years (interquartile range (IQR): 1.8–9.5 years) for hypothyroidism and 7.4 years (IQR: 3.1–13.5 years) for hyperthyroidism. Hyperthyroidism was associated with a slightly increased breast cancer risk compared with the general population (SIR: 1.11, 95% CI: 1.07–1.16), which persisted beyond 5 years of follow-up (SIR: 1.13, 95% CI: 1.08–1.19). In comparison, hypothyroidism was associated with a slightly lower risk of breast cancer (SIR: 0.94, 95% CI: 0.88–1.00). Stratification by cancer stage at diagnosis, estrogen receptor status, age, comorbidity, history of alcohol-related disease and clinical diagnoses of obesity produced little change in cancer risk.ConclusionsWe found an increased risk of breast cancer in women with hyperthyroidism and a slightly decreased risk in women with hypothyroidism indicating an association between thyroid function level and breast cancer risk.

PURPOSE: Young women who are exposed to chest irradiation for Hodgkin’s disease (HD) are at increased risk of breast cancer; this study investigated patient awareness of breast cancer risk and patient screening behavior and assessed the utility of mammographic screening in HD survivors. PATIENTS AND METHODS: This is a prospective cohort study of 90 female long-term survivors of HD who had been treated ≥ 8 years previously with mantle irradiation (current age, 24 to 51 years). Participants completed surveys of their perceptions of breast cancer risk and screening behaviors and received written recommendations for breast examinations and mammography. Annual follow-up was conducted through medical records, telephone, and/or mailed questionnaires. RESULTS: At baseline, women were often unaware of their increased risk of breast cancer; 40% (35 of 87) reported themselves to be at equal or lower risk than women of the same age. Only 47% (41 of 87) reported having had a mammogram in the previous 24 months. Women who had received information from an oncologist were more likely to assess correctly their risk than women who received information from other sources (P < .001). Ten women developed 12 breast cancers (ductal carcinoma-in-situ [n = 2], invasive ductal carcinoma [n = 10]) during the study; two were diagnosed at study entry, and 10 during follow-up (median, 3.1 years). All cancers were evident on mammogram, and eight of 10 invasive cancers were node negative. CONCLUSION: Practitioners who care for women after HD therapy need to educate patients regarding their risks and begin early screening. Screening by mammography can detect small, node-negative breast cancers in these patients.

A total of 396 breast cancer cases and 396 population-based controls from the South African Breast Cancer study (SABC) matched on age and demographic settings was included. Validated questionnaires were used to collect dietary and epidemiological data. Dietary patterns were derived using principal component analysis with a covariance matrix from 33 food groups. Odds ratios and 95% confidence intervals were estimated using conditional logistic regression. A traditional, a cereal-dairy breakfast and a processed food dietary pattern were identified, which together explained 40.3% of the total variance in the diet. After adjusting for potential confounders, the traditional dietary pattern and cereal-dairy breakfast dietary pattern were inversely associated with breast cancer risk (highest tertile versus lowest tertile) (OR = 0.72, 95%CI: 0.57–0.89, p-trend = 0.004 and OR = 0.73, 95%CI: 0.59–0.90, p-trend = 0.004, respectively). The processed food dietary pattern was not significantly associated with breast cancer risk. The results of this study show that a traditional dietary pattern and a cereal-dairy breakfast dietary pattern may reduce the risk of developing breast cancer in this population.

Rice Diet

Although a number of studies explain the association between dietary patterns, which take into account that foods are eaten in combination, and breast cancer risk, the findings are inconsistent. We examined the association between dietary patterns and multi-grain rice intake, and the risk of breast cancer in a large-scale prospective cohort study in Korean women. A total of 93,306 women aged 40–69 years from the Health Examinees-Gem (HEXA-G) study (2004 and 2013) were included. We obtained Information on cancer diagnosis via linkage to the Korea Central Cancer Registry. Factor analysis was conducted to obtain dietary patterns, and Cox proportional models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (95% CI) for breast cancer risk. For 494,490 person-years, 359 new cases of breast cancer occurred. We identified three major dietary patterns, that explained 23.9% of the total variance based on daily total food intake (g/day) from 37 food groups: the meat dietary pattern (higher intake of bread and red meat), the white rice dietary pattern (higher intake of white rice and lower intake of multi-grain rice), and the other pattern. Women who had higher white rice dietary pattern scores had a 35% higher risk of breast cancer, than did women with lower white rice dietary pattern scores (multivariable HR 1.35; 95% CI 1.00–1.84 for the highest vs. lowest quartile of the white rice dietary pattern scores, p for trend = 0.0384). We found that women who consumed three or more servings of multi-grain rice per day had 33% lower risk of breast cancer than did those who consumed one or less multi-grain rice serving per day among women under 50 years of age (multivariable HR 0.67; 95% CI 0.45–0.99, p for trend = 0.0204). Our study suggests that a multi-grain rice diet may be associated with lower risk of breast cancer in Korean women.

Purpose Breast cancer is the most increasing female cancer worldwide, including Bangladesh. The purpose of this study was to investigate the association between dietary patterns and knowledge perception of breast cancer risk patients in Bangladesh. Design/methodology/approach A questionnaire survey about 27 frequently consumed food items was conducted among 140 patients in Amader Gram Cancer Care & Research Center. A logistic regression was applied to estimate breast cancer risk. Dietary patterns were analyzed by the principal component analysis: the fat-rich foods (meat, oil, etc.), fruits, vegetables, sugar, tea, coffee, eggs and fish patterns. Findings The marginal effect of the logit model estimated an increased risk of breast cancer for a“Fatty Diet”, characterized by a higher consumption of milk (1.2 per cent, p < 0.01), vegetable oils and fats, butter (3.7 per cent, p < 0.05) and red meat (4.9 per cent, p < 0.05), but a decreased risk of breast cancer for a “Fruity and Vegetable Diet”, characterized by a higher consumption of fish (1.3 per cent, p < 0.01), chicken and eggs (5.1 per cent, p < 0.05), fruits (0.05 per cent, p < 0.01) and vegetables (2.9 per cent, p < 0.05). The findings of this study also suggested that weight (0.07 per cent, p < 0.01) and age (19 per cent, p < 0.05) were associated with an increased risk of breast cancer, but exercise (13 per cent, p < 0.05) reduced breast cancer risk. The findings also showed that maximum patients had inadequate knowledge on dietary and clinical factors of breast cancer risk, in addition to poor cancer screening practice. Poor knowledge and practice of breast screening were likely to lead to late stage presentation of breast cancer. Originality/value The authors found an association between the prudent dietary patterns and breast cancer risk and poor knowledge on nutrition and breast cancer.

Risk Reduction Strategies

High mammographic density is associated with a two- to sixfold increased risk of breast cancer. Mammographic density can be altered by endogenous and exogenous hormonal factors and generally declines with age. Mammographic density is affected by confounding factors such as age, parity, menopausal status, and body mass index (BMI), thus making interpretation of mammographic density challenging. None of the established means of measuring mammographic density are entirely satisfactory because they are time consuming and/or subjective. Although mammographic density has been shown to predict breast cancer risk, the role of mammographic density in precisely assessing a woman's breast cancer risk over her lifetime and evaluating response to risk-reduction strategies cannot be fully realized until we have a better understanding of the biology that links mammographic density to breast cancer risk.
