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.
No Bra Day
The original event known as "BRA Day" was started by Toronto plastic surgeon Dr. Mitchell Brown. The first BRA Day event, titled "Breast Reconstruction – An Evening of Learning and Sharing", was held in Toronto, Canada at Women's College Hospital and Toronto General Hospital on October 19, 2011. Brown found that many Canadian women who underwent a mastectomy due to breast cancer resisted undergoing reconstructive surgery. He founded "Breast Reconstruction Awareness" (BRA) Day to increase women's awareness of the availability of reconstructive breast surgery. BRA day is intended to raise awareness of breast cancer screening, alert women to breast cancer symptoms, and to encourage women to conduct regular self examinations. The event was adopted in the U.S. in 2012.
