I've had saline implants under-muscle since '07 to correct asymmetric A/AA breasts. My breasts look great, but I worry that my autoimmune issues could be caused by BII. 1. Is an En Bloc capsulectomy recommended with possible BII? Pros & cons? 2. Pros & cons of simultaneous implant exchange w/fat vs transfer after 6-12 mths? 3. Would fat be transferred under the skin or in empty space left under the muscle? 4. Is breast lift also recommended? Effect on appearance & recovery?
