“…In a recent meta‐analysis, a linear dose‐response relationship between increasing calcium intake and lower breast cancer risk was reported, with the lowest risk observed for intake around 600 mg/day . It has been suggested that the actual amount of calcium intake needed to observe beneficial health effects may be greater in populations with diets high in sodium and/or animal protein . High levels of calcium intake are typical in Western populations, and a protective effect against breast cancer development was observed for calcium intake levels of at least 800 and 1,366 mg/day in the Nurses' Health Study and Women's Health Study, respectively.…”

There is experimental evidence that calcium protects against breast cancer development. Prospective epidemiologic studies supporting a protective effect of calcium on breast cancer risk have mainly been limited to Western populations. We examined the association between calcium intake and breast cancer risk in the Singapore Chinese Health Study, a large population-based prospective cohort. Calcium intake and supplement use was assessed by in-person interviewer using a validated food frequency questionnaire. After a mean follow-up of 14.2±3.5 years, 823 cohort participants developed invasive breast cancer. Multivariate proportional hazards regression models were fitted to examine the associations between calcium intake and breast cancer risk. Vegetables were the primary food source of calcium in this study population, followed by dairy products, grains and soy foods. Calcium intake was not associated with breast cancer risk, comparing highest quartile (>345.6 mg/1000 kcal/day) to lowest quartile (<204.5mg/1000 kcal/day) of intake. There was no evidence of effect modification by menopausal status, body mass index, dietary vitamin D or stage of disease at diagnosis. Our findings do not support a hypothesis for calcium in breast cancer chemoprevention, contrary to findings from previous studies among Western populations with higher calcium intake primarily from dairy products and supplements.

“…Several studies have suggested an inverse association with dietary calcium and breast cancer risk, as reviewed by Cui et al 12. However, the relation between dietary intake of calcium and serum levels is complex, influenced by vitamin D and PTH, but also by other dietary factors,54 and a large cross‐sectional study found no significant association between dietary intake of calcium and serum calcium levels 55…”

BACKGROUND: This paper examines the prevalence of cancer screening use as reported in 2005 among US adults, focusing on differences among historically underserved subgroups. We also examine trends from 1992 through 2005 to determine whether differences in screening use are increasing, staying the same, or decreasing. METHODS: Data from the National Health Interview Surveys between 1992 and 2005 were analyzed to describe patterns and trends in cancer screening practices, including Papanicolaou test, mammography, prostate-specific antigen, and colorectal screening. Logistic regression was used to report 2005 data for population subgroups defined by several demographic and socioeconomic characteristics. RESULTS: Rates of use for cancer tests are rising only for colorectal cancer, due largely to the increase in colorectal endoscopy screening. Use of all the modalities was strongly influenced by contact with a physician and by having health insurance coverage. CONCLUSIONS: There remain large gaps in use for all screening modalities by education, income, usual source of care, health insurance, and recent physician contact. These specific populations would benefit from interventions to overcome these barriers to screening. Cancer 2010;116:4872-81. Published

Calcium concentration in water varied substantially from different sources in the USA and Canada. Bottled waters presented with concentrations of calcium covering a very large range. Certain tap and bottled waters present with concentrations of calcium sufficient to exhibit a deleterious effect on bisphosphonate treatment. Alternatively, certain waters may be used as a source of calcium that may provide over 40% of the recommended daily intake for calcium.
