Is 800cc high profile good? 5'5", 115-120lbs, broad shoulders, 2 BAs with 2 benelli lifts. 5.5 mos post op 2nd BA (Photo)

Thank you for the question and pictures.  Definitive advice would require in person evaluation but breast lifting does seem to be a good idea.

Generally speaking, the best online advice I can give to ladies who are considering revisionary breast augmentation surgery is:

1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals.
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or "up a cup size” or "DD cup" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate.
3. Once you feel you have communicated your goals clearly, allow your chosen plastic surgeon to work with you in determining the best plan to achieve your goals.

I hope this, and the attached link (dedicated to "larger" breast augmentation surgery concerns), helps. Best wishes.

The larger the implant, the more risk of having a problem due to the weight and early sagging, malposition, etc..
