Is this snoopy deformity? I'm a year post-op (Photo)

It appears that your nipple is sitting relatively low on the breast mound. The cause of this and treatment options cannot be determined without more photos, including preoperative views. You should also discuss your concerns with your surgeon.

A single view of one breast without perspective of the rest of your chest gives little info other than a nipple areolar complex low on the mound. If you want to know the reason you'll need better photos or perhaps an in person examination.
