This summer the FDA updated its information resources related to breast implants. As the FDA writes, "Breast implants are medical devices that are implanted under the breast tissue or under the chest muscle to increase breast size (augmentation) or to rebuild breast tissue after mastectomy or other damage to the breast (reconstruction). They are also used in revision surgeries, which correct or improve the result of an original surgery."
The FDA pages on breast implants are a good resource for unbiased information and worth review for anyone who is considering breast implants or has had implant surgery. The information is designed to support, not replace, the relationship that exists between patient and physician. Check it out at: FDA Breast Implants.
