Study data suggested that the daily consumption of multivitamins can reduce death rates among post-menopausal women with breast cancer by 30 percent, The Daily Mail reported.
"We don't know how these multivitamins and minerals might work, but they could contribute to women's overall health, which may help them better withstand the assault that cancer represents, said study author Sylvia Wassertheil-Smoller.
In the study, the researchers evaluated survival rates among nearly 8000 women between 50 and 79 years of age who had been diagnosed with invasive breast cancer, about a third of whom consumed multivitamins over an average of seven years of follow-up.
Specialists note that women who take multivitamins are likely to be healthier than their counterparts, as they tend to be thinner, less likely to smoke and more likely to exercise.
However, Wassertheil-Smoller mentioned that their findings remained significant after controlling for these factors.
The researcher added that multivitamins did not improve survival among younger women with breast cancer.
