Is it possible that 500 grams of breast tissue be removedfrom c-cup breasts?

Not likely: 500 grams in a c-cup breast will leave you with breasts that are going to be flat and too small. Breast reduction should be done to leave your breasts proportional to your size.

Breast Reduction: I show my potential breast reduction patients a 500 gram breast implant to give them an idea of how much breast tissue will be removed and how much will remain. You should consult with a board certified plastic surgeon. Cup size is not always an accurate indication of breast size.
