Iron has also been thought to increase free-radical damage in the body and been linked to an increased risk of cancer and aging. The Miller-Keystone Blood Center says that consistent blood donation associated with lower risks of cancers including liver, lung, colon, and throat cancers due to the reduction in oxidative stress when iron is released from the bloodstream.
