62 years old. Implants placed 20 years ago, saline, on top of muscle. Drained by needle 1& 1/2 years ago. Enlarged lymph nodes under arm 2 months ago. Sac and scar tissue/encapsulated area removed 3 days ago. I chose to not get another implant or breast lift. I have a drain in each breast. Of course the breast appears fairly flat right now. Will the breast eventually fill in with fat tissue? If so, how long would it normally take? Thank you!
