Different size breasts. Is this normal?

You did not post photos, but I suspect you may have a capsule of one breast, or may have not be equal in size. Please discuss your concerns with your surgeon.

Dear Enthusiastic341691,
I understand your concern. Sometimes, different implant size can happen after surgery but in most cases it is a minor asymmetry. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

It's not uncommon for breasts to have slight differences in size and shape, even after breast augmentation surgery. However, if you've noticed a significant change in size or shape between your implants, it's always best to consult with a qualified plastic surgeon or your healthcare provider to get an accurate evaluation.

Aesthetic differences in breast size can occur due to various factors, such as differences in the healing process, tissue characteristics, or how the implants settle over time. It's possible that one breast may have settled differently or experienced a different rate of healing, leading to the perceived size difference.

A ruptured implant is a possibility, although it would typically be accompanied by other symptoms such as pain, changes in breast shape, or a noticeable change in the feel of the implant. If you're concerned about a potential rupture or any other issues with your implants, it's important to consult a professional for a proper examination, possibly including imaging tests like an MRI.

I hope this helps,
best of luck !
