Abstract: Iron is one of the metal elements necessary for normal human physiological functions.Studies have indicated that the deficiency or overdose of iron leads to cancer and other diseases.Iron is important in inhibiting the development of colon, liver, lung, and breast cancers.Therefore, reducing iron dust pollution in the work environment and controlling iron storage in the body are good strategies in the prevention of cancer, although controlling iron intake requires time.This study provides new ideas for cancer treatment.
