It is important to understand the different types of estrogen that we are exposed to on a daily basis. There are basically three types – xenoestrogens (man-made/synthetic), human estrogen (that our own body produces) and phytoestrogens (estrogen like substances found in plants).
These estrogens are powerful and very dangerous. They can increase the estrogen levels in the human body leading to the condition “estrogen dominance”. Steps should be taken to avoid these substances although complete avoidance is impossible because they are in the environment. They can be found in products such as plastics, gasoline and pesticides. I have devoted a whole page to this subject – please check out that page for more information.
Human (endogenous) estrogen
This is the natural estrogen produced by the ovaries. The levels in the body are regulated by the pituitary gland through the action of lutenizing hormone (LH) and follicle stimulating hormone (FSH).
These are weaker estrogen like substances that are found in plants. Please see “Helpful Diet Tips” for a list of foods that contain these substances. Phytoestrogens actually help to reduce the level of estrogen in the human body, and many studies have shown a link between these substances and a lower cancer risk for estrogen dependent tumors
So What Does This Mean?
Here is a very simplified explanation. Remember that this is basic – many more hormones are involved in the proper functioning of the reproductive tract!
Adenomyosis has been shown to be estrogen dependent meaning that it needs estrogen to grow. The body has a certain number of estrogen receptor sites and constantly “fills” these sites. If they are “filled” with too many xenoestrogens, the resulting condition is estrogen dominance. Too much estrogen can lead to adenomyosis or estrogen dependent tumors. If the sites are “filled” with a lot of phytoestrogens, the estrogen levels are lower. Not enough estrogen, adenomyosis can’t survive or at least won’t progress as fast.
There is no such thing as an absolute in medicine…..
Although many studies show that the phytoestrogens in flaxseed to be beneficial, a study done at the University of Pittsburgh has shown that the phytoestrogens in flaxseed oil actually stimulate the growth of breast cancer cells. Please keep in mind that studies on any disease/disorder can have conflicting results. Based on my research, I have found many more studies showing the benefits of phytoestrogens in reducing cancer risk. However, if you have a family history of estrogen dependent cancers (uterine, breast, ovarian), please keep this in mind and talk to your doctor before supplementing your diet with flaxseed oil.
