Breast augmentation — also known as augmentation mammoplasty — is surgery to increase breast size. It involves placing breast implants under breast tissue or chest muscles.
For some women, breast augmentation is a way to feel more confident. For others, it's part of rebuilding the breast for various conditions.
Breast reduction surgery (also known as reduction mammoplasty) is an operation to remove extra fat, tissue, and skin from your breasts. You might consider it if you have very large breasts (sometimes called macromastia or gigantomastia) that are making you self-conscious or causing neck pain, back pain, or other symptoms.
