#573 - The Truth About Breast Cancer -- Part 3

The evidence implicating natural estrogen is pretty convincing. If a woman starts having her period early in life or goes through menopause late, her chances of getting breast cancer are increased. Not having a baby at all, or having the first baby late in life, increases the likelihood of breast cancer. Having more babies is more protective against breast cancer --having more than 5 is most protective.[2] Breast feeding seems to be protective (though it is unclear exactly why). Having one's ovaries surgically removed is VERY protective; in pre-menopausal women, the ovaries are the major source of natural estrogen. In sum, for unknown reasons, under some circumstances, prolonged exposure to natural estrogen increases the likelihood of breast cancer in some women.[1]
