Hi Fiona:) I am on Tamoxifen,but not long after I started it,I noticed this facial hair,kind of like peach fuzz,round the side of my face.At the same time,there was a blog post on here about the same thing.Several ladies came on and they also were experiencing this.I think you will find its not from chemo,but from the hormone medication.I read somewhere that it's common.The only ' good' thing about it is that it doesn't get any worse.I just leave mine alone,because I'm scared that it might grow more if I remove it!!!!!Maybe just use a hair removal cream? Cheers Robyn
