I do a lot of breast reduction by liposuction, and patients love the procedure.
I warn them that I can't guarantee two things. First, I can't promise how much weight and volume liposuciton will be able to remove. Sometimes we get as much volume off as the patient wanted, but sometimes not. Second, I can't always predict how much the breasts will "snap up" after being emptied of some weight v. laying flatter against the body. Thicker, younger skin with less stretch marks and droopiness does better than the opposite, but you can't know for sure ahead of time how it will end up. In the worst case scenario, you then get a lift later.
One thing to tell you, though, is that 2/3 of women that get standard reductions can lactate anyhow, which is about the same percentage of large breasted women who can lactate. So while we warn all women getting reductions that they may lose that ability, the reality is that it probably doesn't change their chances of breast-feeding very much.
