If I'm a Size 38F What Will my Size Be After Having 500 Grams Took of Each Breast?

Thank you for the question and congratulations on your decision to proceed with breast reduction surgery; this operation tends to be one of the most patient pleasing operations we perform.There is no direct correlation between the amount of tissue removed and the ultimate cup size that a patient will wear after breast reduction surgery.Before undergoing the breast reduction procedure it will be very important to communicate your size goals with your surgeon (who you should choose very carefully). Most patients wish to achieve enough of a reduction to help with their symptoms while remaining proportionate with the remainder of their torso.
With the goal of improving communication with my patients I find the use of photographs of “goal” pictures (and breasts that are too big or too small) very helpful. For example, I have found that the use of words such as “natural” or “B,C,or D cup” means different things to different people and therefore prove unhelpful. Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate.

Once you have communicated your goals carefully, your plastic surgeon will be able to provide you with an estimation of how much tissue will need to be removed, in order to achieve your desired outcome.
Best wishes with your breast reduction procedure; hopefully you will be very pleased with the outcome of the procedure performed. 

I have always been amazed when I see patients and they describe their cup size.  Each bra company is so different and so to guesstimate your cup size can be difficult. Assume that you may go down two cup sizes with 500 gm removal in most average breasts.

Hi.

You are very large. The best size for most women like you is a small D cup.  I don't have all the facts, but my guess is you will need 700 grams removed from each breast.  So I would not worry about being too small.

No one can authoritatively answer your question.  First of all, there are no uniform cup sizes.  My best guess (if you continue to wear a similar bra) is that a 500 gram reduction would take you from a 38F to about a 38D.
