Narrator: Can you get breast cancer from a bioidentical hormone?
Laura Corio, MD: You can get breast cancer from anything. I mean nobody knows what causes breast cancer, but bioidentical hormones are still hormones. They are still estrogen.And women think they are not going to get you know a risk, from taking bioidentical hormones because they are bioidentical. That's not true, it's estrogen, it's testosterone, it's progesterone.Women have to be watched for uterine and breast cancer, but again, we don't want to take it long term.
