How big are 500 gram breast implants?

I
think there is way too much emphasis on cc’s and there should be more emphasis
on the profile of the implant.  For
instance, these are both 300 cc implants, but you can see that the shape is
very different.  This is a moderate
profile implant that looks flatter and will give you a more natural look.  This 300 cc high profile implant will give
you a rounder look. 
During
our consultation, we will go over before and after photos.  Based on the photos that you like, we will
choose the profile of an implant.  Then,
I will measure the dimensions of your chest. 
Knowing the profile of the implant and your breast dimensions, we can
come out with an estimated cc. 
 

500 gram implants have a volume of approximately
500 cc’s. 500 cc implants would change
you from a 36 C to between a DD and DDD, weigh approximately 1 lb, will not be
stable long term, will descend inferiorly and laterally requiring
revision. 22% of women who undergo
breast augmentation alone require revision within 2 years because they are
dissatisfied with the result. A frequent
cause of dissatisfaction is over implantation.
I do not recommend 500 gram implants.Best Wishes,Gary Horndeski, M.D.

    500 cc may increase breast cup size by 2 to 3 cup sizes.Kenneth Hughes, MDLos Angeles, California ...

500 cc implants are 500 gms or 0.5 kgs or just over 1 lb of weight.  Good luck in choosing to move ahead with surgery.

All current FDA approved breast implants that I'm aware of our measured
in cc not in grams. A 500 cc breast implant is quite large. Generally
speaking 150-200 cc of breast implant is equivalent to 1 cup size thus
500 cc breast implants could increase her cup size by a factor of 3.
