I'm 180 and 5'8 is 700cc Too Big?

700 cc breast implants are very big.  Please be sure that you have tried these on in your surgeon's office and you are comfortable with the look this will create.  Good luck.

Thanks for your question.  I would not reccomend such large implants, make sure you get another opinion of a board certified surgeon in your area.

700 cc implants are generally in the very large range of implants.  It will result in the obviously augmented look vs the natural look.  If you tried them in the office with a sports bra and you liked that look, then they are right for you.  Another option for you would be an augmentation with a more reasonable size and a mastopexy to correct your nipple asymmetry.
