They ARE big and heavy.
I fully agree with the comments by Drs. Whitt, Yuan and Stratis and would like to amplify on their comments.
For lack of a better language to communicate volume we are collectively stuck discussing bra cup sizes - a VERY inaccurate measuring tool. After all, ALL women KNOW that they just fit better in certain manufacturers bras than others. Why? Because EACH manufactuers bra cups are different. If Engineers were to use such divergent and inconsistent measurements no building would have a second floor!
To get THE BEST breast augmentation several factors need to looked at before others.
BREAST COVER FOR THE IMPLANT - without adequate breast coverage the implants will look like two grapefruits under a table cloth. How often have you seen this result? So we start by measuring what you have and pick the implant diameter based on this.
SKIN LAXITY - obviously the laxer the skin, the larger or more projecting implant it allows in. Put another way, two identical twin sisters aged 25; one without children; the other had two. Obviously, the latter breasts would allow larger implants.
CHEST WALL WIDTH - the wider the chest flatness, the more likely a larger (wider) implant is to remain ON the chest rather than sliding to the sides when you lay on your back. So the flat area can sway the choice between a Moderate Profile or a High Profile (narrower base) implant
AND LOCATION OF THE NIPPLES - the implants need to be placed dead center under the nipples wherever they may be.
In MY opinion a 34 A (meaning not a lot of breast cover) would look artificial with 650cc implants. Moreover, the HEAVIER THE IMPLANTS THE FASTER THE BREAST SAGGING. Please, seehttp://www.cosmeticsurgeryspecialists.org/bodyprocedures/breastaugmentation.html#
I would get a second opinion.
