Hi there and sorry to hear of your troubles...I can understand your anxiety.
My husband was recently diagnosed with an iron overload disorder called hereditary hemochromatosis. It is a genetic disease that causes a person to store excess iron instead of getting rid of it. Pancreas and gallbladder two of the most affected organs, right after liver and heart. Cancer is very high in people with iron overload, and drs are constantly misdiagnosing this common disorder. It is getting missed until end stage organ damage, cancer, or even death. Iron overload is extremely life threatening when not detected early and treated. When it is detected early in the symptoms and treated then prevention of disease and death is the result.
Please research the effects of too much iron, and I can assure you, you will be amazed at the connections between iron and so many common ailments we and our loved ones deal with and are diagnosed with, with iron as the leading cause of such diseases.
