I have a few problems with this study:
1. Nowhere do they say how much they were injecting
2. It was injection, not topical application
3. It was mice, not people
4. Nowhere does it mention the pre-study hormone status of the mice.

I am absolutely NOT a proponent of supplementing high dose almost anything unless there is a proven need, but I don't see how supplementing a physiologic dose of something the body produces naturally can cause cancer in and of itself. Physiologic means a dose no more than replacing what the body fails to make vs pharmacologic or therapeutic which is a dose much greater than the body produces.

SubQ injection would give an immediate surge of the hormone in the body. This is not natural. The ovaries and adrenal glands trickle the substance out continuously so the body is never subjected to a huge peak and valley of the hormone.

Mice aren't people, sorry. I think just about anything in the wrong doses or when other things are out of whack can cause cancer. There isn't enough information presented in this article and it keeps saying "reasonably anticipated to be human carcinogens” meaning they were looking to skew the results to prove carcinogenicity. I'm not saying if I had access to the full study, I might change my mind, but this article as presented does not meet my standards.
