Usually if a woman wears a size 36 AB bra and would like to be a C cup, which is the average size that women wear and the average size bra that is sold, she needs a volume of approximately 350 to 390 cc to make that change. This becomes less if she's wearing a 34 bra, because it has a smaller strap size and the cups have a smaller diameter. A smaller diameter implant would then be a volume of approximately 300 to 350 cc. In the same way if she was more petite, maybe a double zero or size one and wore a 32 AB bra, then to become a 32C cup she would only require about 250 to 300 cc. This is a general number, and of course there are other factors that will affect this. Other factors which contribute to the outcome are size, shape, and profile. The #profile is determined by the amount of #projection versus roundness that the you desire, as well as the #size of the implant and size of your chest. Also, the placement or incision location will also have an effect on profile. However, #BreastImplants without a #BreastLift is usually said to be mistake by many patients who reflect back on the decision. Most breasts will look larger and more droopy with solely implants. They will sag more and sooner, due to the sudden and excess weight. At times it's possible for a “Snoopy” breast or double bubble to develop as a result. Additionally, an implant with lift may be useful to re-position the nipples which may have been affected by ptosis or drooping. One of the primary intentions of a Breast Lift (#Mastopexy) is to improve the shape and position of the breast without reducing their size. It is used especially for breasts which sag or droop (#ptosis).Talk to your surgeon at greater length and be sure to view before and after pictures and reviews beforehand to gain more reassurance of the procedure.
