Metformin. Is anyone on this

Hi been reading some of you mentioning metformin. It is supposed t help stop cancer cells is what I understand does anyone kno anything about this or kno anyone taking it x rozita

I started a post somewhere as i was put on metaformin but couldnt take it because of the se of chemo at the time were bad so gp said leave it for a few weeks so should be starting it soon. Also big thread on here somewhere about the possible trials going on if you go to search and put metaformin in it should bring up threads containing it.
