What is the exact definition of cc when used for implant sizes?

You go it, remember a can of cola has about 330cc of fluid in it so that is a good way of thinking about volumes

Yes.  All of those statements are true.Kenneth Hughes, MDLos Angeles, CA.................................

The "cc", as you suggested, does stand for cubic centimeters, and is a measure of volume.  Saline, standard cohesive silicone gel implants (Natrelle and Mentor round, smooth implants) and Natrelle highly cohesive (style 410 implants) all weigh approximately 1gm per cc.Other factors, besides weight, however, will determine how the implant will influence the overlying breast tissues, including the shape and surface of the implant, as well as the type of filling and implant location within the breast.I hope this information is useful.

cc stands for cubic centimeters which is a measure of volume.   Cubic centimeters is not a measure of weight which is why saline and silicone implants of the same volume do not weigh the same

One cc is a volume measurement (cubic centimeter) defined by the volume of a cube with sides of 1 cm. The weight of the contents varies with the "specific gravity".   The s.g. of saline is 1, so each 100 cc of saline weighs 100 grams. THe s.g. of silicone is 0.97, so each 100 cc of silicone weighs 97 grams.In addition, the shell itself has some weight, and it will vary by size of implant.  Average would be about 25 grams.All the best. 

You understand things correctly. The cc measurement is a volume measurement of cubic centimeters. The weight depends upon the density of the material. Think of 1 cc block of gold vs. 1 cc of water. Same volume, different weights (and value) ;-).

He has you are correct the designation of cc when referring to breast implants refers to the cubic centimeters of liquid volume.  As others have mentioned the weight depends on density  with silicone being heavier than water.For more information on breast implant sizes in cc read the following link:
