Low Iron Linked To Higher Cancer Risk In 1.3M Women

A large-scale study of 1.3 million women found an association between iron deficiency anemia and an increased risk of developing certain cancers, including colon, lung, and bladder cancer, over an 18-year period. Published in *BMC Medicine*, the research suggests iron's role in cell growth might be a factor, though it doesn't prove causation. This flags another reason to get your ferritin checked, especially if you're already low.
