Multivitamins Linked With Reduced Risk of Invasive Breast Cancer Mortality
Breast cancer is the second leading cause of death by cancer in women, with only lung cancer claiming more lives. A recent study suggests that taking a multivitamin with minerals supplements may increase the chances of survival in women with invasive breast cancer by 30%.
The cohort for this study included 161,608 women between the ages of 50 and 79 at the onset of the Women’s Health Initiative (WHI) Observational Study. For this subset investigation, the researchers focused on the 7,728 women who were diagnosed with invasive breast cancer during the study.
The researchers followed the women for an average of seven years after they were diagnosed. They determined through questionnaires administered at the onset of the study and at follow-up visits that 38% of the women who developed breast cancer were taking multivitamin with minerals supplements. The majority of them had been taking the supplements prior to their diagnosis.
After analyzing the data and controlling for lifestyle factors such as smoking, education, race/ethnicity, weight, depression, alcohol consumption, physical activity, age at diagnosis, diabetes, and other supplements, the researchers found that the women who took multivitamin with minerals supplements were 30% less likely to die from cancer than those who were not.
Researchers from Yeshiva University conducted the study. It was published online ahead of print in Breast Cancer Research and Treatment on October 9, 2013.
Previous studies have shown that multivitamins may aid in weight loss, reduce the risk of cardiovascular disease, and boost general physical health. Other studies have also shown that the cells of people who routinely take multivitamins have a younger biological age.
