11 Feb 2017 News

A study published in May this year researchers at the National Institute of Health in the United States evaluate the relationship between the use of complexpolyvitamin and incidence (number of new cases per year) of prostate cancer. Lawson K. and colleagues analyzed in 295334 people through a questionnaire(1195-1996) eating behavior, use of vitamins, demographics factors and behaviors related to health and followed prospectively over 5 years. There was aparticular form the association between the use of vitamins and the risk of prostate cancer.
The test showed that the use of multivitamins was not associated with an increase in the number of cases of localized prostate cancer, but was found that men who used multivitamin complex over 7 times a week doubling the risk of advanced prostate cancer (spread to other organs) with regard to those who did not use any vitamin supplementation. The incidence of advanced prostate cancer or fatal (number of new cases per year) compared with 113 and 11 for men who belonged to the second group. Alongside a supplementary analysis showed increased risk in men with a family history of prostate cancer and with intake of micronutrients such as zinc, selenium and beta carotene.
This study demonstrates that the use of polivitamínicos does not increase the incidence of prostate cancer. The results in terms of advanced prostate cancer deserve further investigation.
Other studies evaluating supplementation with vitamin D and E not shown to reduce the incidence of digestive tumors or prostate cancer but not increase it. The results are not yet conclusive to recommend its administration.
