Will a 100CC Decrease in Silicone Make a Cup Size Difference?

If you are a 32 or 34 each 100 cc’s of implant corresponds to 1 cup size change.  If you are a 36 or 38 each 200 cc’s of implant corresponds to 1 cup size change.  From this, you can calculate the breast size after 100 cc reduction.  However, another alternative to consider is a new technique called Implant Exchange with Mini Ultimate Breast Lift.  Using only a circumareola incision it is possible to exchange your implants with smaller ones, reshape your breast tissue creating upper pole fullness, elevate them higher on the chest wall and more medial to increase your cleavage.  Aligning the areola, breast tissue and implant over the bony prominence of the chest wall gives maximum anterior projection with a minimal size implant.  Smaller implants are more stable long term, look and feel more natural, are less likely to ripple or to have complications that need revision.  It is possible that you can go down to a smaller size and still obtain the projection you want.

Thank you for your question. Cup sizes are a very vague thing as cup variations from one manufacturer to another are difficult to predict.  A "B" in one brand is a "C" in a Victoria's Secret and there is no standardization of bra sizes so the question is hard to answer, and would be dependent on which type of bras was used.  The bottom line is decreasing 100C is significant, and the concern may be if the decrease in volume requires a lift if there is skin laxity.  That would be the question I would be concerned about.  In the same brand of bra, I would guess that at least a half to a full cup is a reasonable expectation. I hope this helps.

If you feel that your breasts are far too big, then you should consider a reduction of more than 100 cc.  You will probably be happy with something in the 300-350 cc range.  Go online (Allergan or Mentor or whatever manufacturer you will be using) and view the implant dimensions.  You will see that a drop from 500 cc to 400 cc is not that much in terms of the dimensions of the implant.  You need about a 200 cc reduction to drop one bra cup size.  But you don't want to go too small either. I rarely insert implants with a 300 cc volume any more.  You don't want a third operation!  Good luck!

Without photos or an exam it is difficult to predict how much a 100 cc reduction will achieve. In general, 200 cc is about a cup size. This is variable as well because the amount of breast tissue you have will influence this difference. 100 cc in a large breast will be a less significant change than in a woman with much less natural breast tissue.

Seek out a board certified plastic surgeon to evaluate you and offer their opinion. Good luck and I hope this was helpful.

If you want a definite decrease in the size of your breasts of at least a cup size, I think you should go at least down to 350 mL.
