Best way to treat fat necrosis 5 years after breast fat transfer? (photos)

I am 33 years old! I had fat transfer surgery about 5 years ago. Unfortunately my right breast got a big fat necrosis (it has been 1.5 years now) It is really bad and my nipple is inverted now (due to fat necrosis)! My doctor suggested to remove it by surgery and put implant but he says it might not look good! Another way is to remove all my breast and put implant to make sure my breasts look smooth and event! I am so sad because I don’t want to lose my whole breast since I don’t have cancer!
