Background: Calcium, vitamin D, and dairy products are highly correlated factors, each with potential roles in breast carcinogenesis. Few prospective studies have examined these relationships in postmenopausal women. Methods: Participants in the Cancer Prevention Study II Nutrition Cohort completed a detailed questionnaire on diet, vitamin and mineral supplement use, medical history, and lifestyle in 1992 to 1993. After exclusion of women with a history of cancer and incomplete dietary data, 68…

Dietary Intake of Vitamin D and Calcium and Breast Cancer Risk in the European Prospective Investigation into Cancer and Nutrition

In this large prospective cohort of 319,985 women, there was no evidence for an association between dietary vitamin D or calcium intake and breast cancer risk and the test for trend was borderline statistically significant.

Intakes of calcium and vitamin D and breast cancer risk in women.

Higher intakes of calcium and vitamin D may be associated with a lower risk of developing premenopausal breast cancer, and the likely apparent protection in pre menopausal women may be more pronounced for more aggressive breast tumors.

Vitamin D intake and breast cancer risk in postmenopausal women: the Iowa Women’s Health Study

Vitamin D intake of >800 IU/day appears to be associated with a small decrease in risk of breast cancer among postmenopausal women, and changes in vitamin D intake over time might have contributed to the diminished association observed in later years.

Vitamin D and calcium intakes and breast cancer risk in pre- and postmenopausal women.

No associations were found between overall vitamin D or calcium intake and breast cancer risk and further research is needed to investigate the effects of higher doses of vitamin D and calcium supplements.

Calcium plus vitamin D supplementation and the risk of breast cancer.

Calcium and vitamin D supplementation did not reduce invasive breast cancer incidence in postmenopausal women and a relationship between total vitamin D intake and 25-hydroxyvitamin D levels with breast cancer risk was not supported.

Long-term dietary calcium intake and breast cancer risk in a prospective cohort of women.

The findings do not support an association between dietary calcium intake and overall breast cancer risk, and the inverse relation between calcium Intake and ER-/PR- breast cancer requires confirmation in other studies.

Long-term dietary calcium intake and breast cancer risk in a prospective cohort of women 1 – 3

The association, if any, of dietary calcium intake with risk of breast cancer by estrogen receptor (ER) and progesterone receptor (PR) status of the tumor was examined in a population-based prospective cohort of 61,433 women who were cancer-free at enrollment in 1987–1990.

Dietary calcium, vitamin D, and breast cancer risk in women: findings from the SUN cohort

Evidence of a non-linear association between total calcium intake and BC risk was found with risk reductions associated with higher intake up to approximately 1400 mg/day, with an L-shaped association among overall and postmenopausal women.

Dairy consumption and calcium intake and risk of breast cancer in a prospective cohort: The Norwegian Women and Cancer study

Dairy consumption is not strongly related to breast cancer risk in this prospective study of 64,904 Norwegian women followed from 1996/1999 through 2006, but a non-significant negative association between calcium intake and Breast cancer risk was seen, particularly among premenopausal women.

Dietary Vitamin D and Calcium Intake and Premenopausal Breast Cancer Risk in a German Case-Control Study

The data support a protective effect of dietary vitamin D on premenopausal breast cancer risk independent of dietary calcium intake, and no statistically significant interaction between the 2 nutrients was observed.



Intake of dairy products, calcium, and vitamin d and risk of breast cancer.

It is found that association with calcium was due mainly to dairy sources whereas the association with vitamin D may be independent of dairy intake, and among premenopausal women, high intake of low-fat dairy foods, especially skim/low-fat milk, was associated with reduced risk of breast cancer.

Dietary Calcium Intake and Breast Cancer Risk Among Chinese Women in Shanghai

Investigation of data from a large, population-based, case-control study conducted in Shanghai, China, between 1996 and 1998 found that calcium derived from milk, seafood, fruit, and vegetables was not associated with risk of breast cancer.

Vitamin D and Breast Cancer Risk: The NHANES I Epidemiologic Follow-up Study, 1971–1975 to 1992

The hypothesis that sunlight and dietary vitamin D reduce the risk of breast cancer is supported and the protective effects of vitamin D observed in this prospective study are consistent for several independent measures of Vitamin D.

Intake of dairy products and the risk of breast cancer.

There is a protective effect, dietary or habitual, associated with consumption of milk that overwhelms the associations between different other factors and risk of breast cancer.

Dietary intake of selected micronutrients and breast-cancer risk.

The relation between 17 micronutrients and breast‐cancer risk was analyzed in a case‐control study conducted between 1993 and 1999 in the Swiss Canton of Vaud and the only persisting significant inverse relations were for vitamin C and lycopene.

Intake of food groups and associated micronutrients in relation to risk of early‐stage breast cancer

Intakes of cereals and grains, vegetables and beans are associated with minimal, if any, reduction in risk of early‐stage breast cancer among young women, and risk was not associated with dietary constituents related to these food groups.

Raw and Cooked Vegetables, Fruits, Selected Micronutrients, and Breast Cancer Risk: A Case-Control Study in Germany

In this population of German women, components of raw vegetables and some micronutrients appear to decrease breast cancer risk in this case-control study of breast cancer.

The overall results from over 20 published case-control and cohort studies suggest that calcium intake is not associated with a substantially lower risk of colorectal cancer.

Vitamin D, calcium and prevention of breast cancer: a review.

Findings from the laboratory recently found that decreased dietary calcium and vitamin D in a high-fat diet induced adverse changes in the mammary gland and several other organs, which were reversed by increasing dietary calciumand vitamin D; the findings further suggest a possible role for increased Dietary calcium anditamin D in the chemoprevention of these cancers.
