AIM: The aims of this study were to investigate the effects of calcium at the same concentration as that found in human milk on the viability, proliferation, and adhesion of MCF-7 human breast ductal carcinoma cells by exposing them to calcium at the same frequency as in breastfeeding.

MATERIALS AND METHODS: High-concentration calcium was applied for 30 minutes every 4 hours for 24, 48, and 72 hours. Cell proliferation and viability were measured using a hemocytometer and the MTT cell viability assay. The effects of calcium treatment were evaluated by a comparison among a multiple-, single-dose calcium treatment, and a control group.

RESULTS: We show that calcium at the same concentration as that in milk caused a decrease in the number of cells but did not affect cell viability.

CONCLUSIONS: The results of this study suggest that calcium caused a lowering of the number of cells from the luminal surface of the breast by triggering proliferation under the condition of fluidity. Calcium and fluidity together serve to eliminate breast cancer stem cells during the lactation period. Effects of the other components of milk can be analyzed by the new method developed in this study.
