The 20%? Just BC. I would imagine there is a specific high risk bar for all cancers though. Also FYI - and for others who might be reading this, there is a current modification before the US House of Representatives to specifically state "alternative" flat closure (already includes flat closure) as a form of reconstructive surgery. The language shift is considered very important to ensure insurance companies recognize AFC as a form of reconstructive surgery and are required to pay for additional follow up procedures (removal of dog ears, fat explants for concavity, change my mind and would like implants). Insurances are required to cover reconstructive care for mastectomy under the US Women's Health and Cancer Rights Act 1998 and the revision is called the Women's Health and Cancer Rights Modernization Act 2025.
