Breast cancer is one of the leading causes of cancer death in women worldwide and breast cancer rates are increasing rapidly.
A compelling number of studies, though not all, have shown that free iron concentrations in breast tissue, especially the ductal tissue, is playing a major role in stimulating cancer development and eventual progression to aggressive, deadly cancers.
Cancers are Very Dependent on Iron
Iron is needed for DNA replication in rapidly dividing cells.
A recent report from the Department of Biomolecular Sciences in Urbino Italy, found that fluid taken from the nipple of cancer patients contained significantly higher levels of aluminum than did nipple fluid taken from women without breast cancer—approximately twice as much aluminum.
A number of studies have found that extracting nipple fluid by a breast pump (in both premenopausal and postmenopausal women) is a simple way to study the microenvironment of the ductal tissue, the site of development of most breast cancers.5
The researchers also found that women with breast cancer had much higher levels of ferritin, an iron transport protein, in their breast fluid, which was 5X higher in women with breast cancer.
This observation has been confirmed in other studies.
