Breast augmentation
The modern prosthetic breast was invented in 1961, by the American plastic surgeons Thomas Cronin and Frank Gerow, and manufactured by the Dow Corning Corporation; in due course, the first augmentation mammoplasty was performed in 1962. There are five generations of medical device technology for the breast-implant models filled with silicone gel; each generation of breast prosthesis is defined by common model-manufacturing techniques.

Since the 1990s, reviews of the studies that sought causal links between silicone-gel breast implants and systemic disease reported no link between the implants and subsequent systemic and autoimmune diseases. Nonetheless, during the 1990s, thousands of women claimed sicknesses they believed were caused by their breast implants, including neurological and rheumatological health problems.
