Men have been warned not to take a pair of popular vitamin and mineral supplements after research showed they can dramatically increase the risk of life-threatening prostate cancer.
Overdosing on the mineral selenium by taking supplements raises the chances of developing high-grade cancer by 91%, US scientists have found.
Vitamin E pills also boosted the risk of aggressive cancer, more than doubling it for men lacking selenium, according to researchers from the Fred Hutchinson Cancer Research Centre in Seattle.
The researchers believe selenium can turn toxic when present in the body at excessively high levels.
