Hi @Siga Welcome to our community. So glad you found us. Wow, wish I'd thought of that before my treatment and surgery began. What a great idea. On timing, I'd suggest you you check in with your cancer care team/oncologist. Once chemo (assuming that's what lies ahead next) begins your immunity levels decrease and the potential for infection increases dramatically. Let them guide you with optimal timing to have this done. I often check in with my oncologist or primary care nurse when I have questions like that in between formal appointments. Usually get an answer back same day.
Take care and do post a picture for us once you've had the new brows. I, and I'm sure others, would love to see the after look.
