I had a double mastectomy with no nipple and areola saving. I am 155lbs and 5’6-5’7 tall. I am having a hard time deciding to stay with 350 cc’s what I have in my expander now or go with a 400 cc’s implant. I took my surgeon’s advice and tried on my bras before mastectomy and am so close in filling but the bottom front between my boobs and the side where my underarms are not totally filling my bra cups. Will 400cc’s make a difference in filling my bra cup gaps? It’s such small cup gapping?
