Multivitamins linked to aggressive prostate cancer
Men who pop too many vitamins may be raising their risk of the deadliest form of prostate cancer, especially men with a family history of the disease, researchers say. Researchers at the National Cancer Institute in Chicago found that men who exceeded the recommended dose - taking more than seven multivitamins a week - increased the risk of advanced cancer by about 30 per cent.
The researchers followed 295,344 men over five years to see if there was a link between multivitamin use and prostate cancer.
“We didn’t see any relationship with overall prostate cancer,” said Dr Michael Leitzmann, a National Cancer Institute investigator who worked on the study.
He said the increased risk from overuse of multivitamins was linked to more aggressive cancer that had spread beyond the prostate gland or cancer that proved fatal.
In men who took too many multivitamins, the risk of aggressive cancer increased by one third, and the risk of fatal prostate cancer doubled compared with those who took no multivitamins, according to the study, published in the Journal of the National Cancer Institute.
