Iron production a detriment to Cancer Cells?

Due to the rapid development of Cancer Cells they need high levels of micro nutrients to sustain their rapid growth. One of them in particular is iron. But this is also a double edged sword. Too much production of iron creates oxygen radicals which damage the cancer cells. Because of this Cancer Cells produce iron storing proteins which keep the levels of Iron in check. What Researchers have discovered is if they can block these proteins that keep the iron levels in check the iron levels rise and so do the oxygen radicals. This kills the cancer cells but renders the normal cells unharmed because they have low levels of oxygen radicals.

This research could create a new way to treat cancer. Right now doctor use chemotherapy and radiation to deal with cancers. Both methods harm the healthy cells and the cancer cells. This creates a dilemma when the patient's body is very weak he or she can not take the chemo because it produces a serious health risk.
