Can anything be done about my buffalo hump if it’s bone? (photo)

I’m a 25 year old female that’s had terrible posture my whole life because of being embarrassed by my big breasts. I recently noticed the hump on my neck but unfortunately, I think it likely bone. I fear that it’s permanent and there’s nothing I can do. Is there any procedure for something like that? I could only find people suggesting liposuction for back fat and while I have put on weight, I think it’s more of a skeleton problem..any advice?
