Hi all- Metformin was recommended to me recently as adjunct to treatment I am already on (Avastin and Etopiside). I am 2 years into treatment and have Stage 4 OC. I'm wondering if anyone has had success using this drug ? Any negative consequences. My alternative doctor thinks I should definitely take it. I haven't brought it it up yet to my Kaiser doctor yet but I think he'll say it hasn't been approved yet so he wouldn't recommend. Thanks for whatever info you can give me. I really appreciate you all!
