Metformin and Breast Cancer Treatment

I am here to educate. I am very focused on how we can improve our healthspan. For women, particularly those at risk for breast cancer or those who want to do hormone treatment after menopause but are worried about the increase in breast cancer risk, are there things we can do to mitigate risk?

In my studies in the depths of PubMed (scientific journal published articles), I have found a treasure trove of information on Metformin and its possible benefits.

PLEASE KNOW THIS IS CONTROVERSIAL. Read my other blogs on the subject, as there is conflicting information out there, and this may not be for everyone. But these are results from published studies, many in experimental mice models. They are interesting and I think bear a listen.

This article concluded that Metformin may help in those who have chemo resistant or radiation resistant cancer cells. 

Metformin, this simple, old, cheap medication, may help in ways we don’t fully understand. I will keep reading and educating on this, as I think there is *something* real here.
