After a Breast Reduction, what are the chances of breasts growing back?

My biggest fear is that my boobs will grow back after some period of time. Any advice/opnions? I'm short, 5"1 and a 32DD in a "roomy" bra. I developed early and have always had back and shoulder pain no matter what bra I wear. I also hate my breasts for getting unwated attention. They sag, don't really have any sensation and basically are just painful. I am finally ready to get them off me and I really scared of going through elective surgery. My fear is............they will come back!! I've heard a few women who did the surgery say that. I am done having kids, but I've heard menopause or birth control pills can even make them grow back again. Would love to hear what you have to say about this. Thank you
