Question about implant shape and volume for revision to address a broken implant on my right side (MRI verified) Current implants are Mcghan style 45 500cc placed in 2002. At the time I purchased the $100 warranty. I am a 36DD. The main issues I have had are: Implants fall into armpits when I lay down (thats not sexy). The breast skin is a little loose with this size implant. Questions: Can I get larger Mentor memory shape textured implant? Does the $100 warranty cover costs?
