Do I need a lift for my tuberous breasts and would I get a good result without having implants? (Photos)

Hello, thank you for your question and provided information as well..
Based in your question and the pictures you  showed, you are a great candidate for a breast augmentation with fat grafting and anchor lift. Since your skin is too saggy because of the tuberous condition, I guess that with these two procedures you could get a beautiful result. But dont dismiss the implants options, trust me, theres so many different types of implants and im sure one can adjust to you. 
In case you think about the implants, know that the size, profile, and shape of the implant is based on your desired breast size/shape, your chest wall measurements, and soft tissue quality.  This decision should be based on a detailed discussion with equal input from both you and your surgeon.   
Best of lucks.

Your breasts are large enough that you do not need implants.  The technique I recommend is a lift using The Bellesoma Method.  This will reshape your breast tissue creating upper pole fullness without implants, elevate them higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained.  Later, fat transfers can be performed if additional volume is desired.  Best Wishes,Gary Horndeski, M.D.
