How small will my breasts look if 200 grams were removed? How about 400 grams?

It is hard to predict what the overall bra cup will be as cup size does not always match volume removed.  You would have to be examined in person to get an idea of the possible volume that might be removed.  I will often use a lollipop incision to minimize incisions.  Best of luck.

Removing 200 grams may not be enough to mitigate against future sagging. Keep in mind that, if you gain weight as you age, this could put you back to your current starting point.  The use of photos during a consultation would be beneficial.  A 200-400 gram reduction would typically not be covered by insurance in New York.
