There are the pictures of actual breast reductions showing the results and what they look like after healing.
Certainly breast reduction is a common surgery which is your choice to do, and that many choose to have done for health, appearance, and personal reasons, including partial and full removals.
And sounds like yours are massive. Maybe consulting a surgeon would help you, and seeing results pics of what they can do.
Definately you can always wait and see if your feelings change, since once their reduced, then you cant go back.
There are a few on this site that have had removals, and at least one that I remember that had a reduction. Maybe a few PMs to them might help you find more info, or hopefully they respond to this post.
