As per the Journal of the National Cancer Institute, iron can increase free radical damage in your system, and this in turn can increases chances of aging, and cancer. Researchers kept track of 1,200 people, divided into two groups, for four and half years. It was found that one group, who donated blood twice a year, experienced a reduction in their iron content, and the other group made no changes. The result was that the donors had lower levels of iron, and thus there were lower risks of cancer.
