En pointe and bunions?

Okay peoples, well, I started dancing (ballet, tap, and jazz), when I was 4 and stopped at 11. I loveee ballet and always dreamed of doing pointe...en pointe, whatever. Lol. But my mom's worried it will hurt my feet, 'cause I have bunions. (I've always had them- they run in my family; they've never given me trouble.) So, is it possible for someone like me to do pointe, or would it damage my feet? (Btw, I'm 15 now; had 7 years of ballet) Any info. mucho appreciated! :DDD
