Does Having a Full Tummy Tuck Make Your Boobs Sag or Appear More Low Slung? Serious Question?

a tummy tuck should have no effect on the position of your breasts. the breast are attached to the chest wall through different attachments that are not released with a tummy tuck

With a full tummy tuck, only the abdominal skin excess will move south, not your breast. There is no reason to fear that your breast will hang lower or sag more after your tummy tuck. Of course, you might notice your breast more if your tummy is set straight.
