The type or amount of scarring will differ based on the type of mastectomy you are having done. The total, radical, and modified radical mastectomies will leave a visibly large scar as a large amount of tissue/skin is removed. However, with partial/lumpectomies, skin-sparing, and nipple-sparing mastectomies, the scars are less noticeable. Skin-sparing mastectomies tend to leave behind a scar that is usually where the nipple was previously. The scar of the lumpectomy is small and linear and tends to be hidden away in the crease or around the nipple to avoid detection. Lastly, the nipple-sparing mastectomy generally leaves a scar under the breast, where it can be tucked away in the bra-line to avoid visibility.
