I'm 36H in breast size. If 500 cc is taken out each breast, what size will that make me? I'm 5'1", 190lbs

Thank you very much for your question.It is very difficult to predict what cup size you will be after your surgery.  Even women who aren't undergoing breast surgery may be different cup sizes based on the bra manufacturer!  What is important isn't absolute cup size, but having a breast size and shape that you like.In breast reduction, there is typically the extra element of pain and symptoms relief (back pain, neck pain, shoulder grooving, rashes underneath the breast).  If insurance is involved, often they require a certain amount of breast tissue to be removed in order for the surgery to be covered.  Removing only 500 cc from a breast in somebody your size may not accomplish these aims.I recommend a consultation with a plastic surgeon for an in-person evaluation and a discussion of your goals.  Best of luck!

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. “Typical” patients who present for breast reduction surgery are women who have disproportionately large breasts, causing problems such as neck/back/shoulder discomfort, postural changes, bra strap grooving, skin irritation/rashes under the breasts, and/or difficulty with activities of daily living and/or exercise etc. There may be both physical as well as psychosocial “stress” caused by the disproportionately large breasts.
Other than the presence of symptoms, the “ideal” patient for breast reduction surgery is one who is psycho socially/emotionally/financially stable, has an excellent social support system surrounding him/her, is capable of arranging enough recovery time, does not smoke and who has reached a long-term stable weight.
Reducing breast tissue mass and elevating the breasts on the chest wall tend to improve or alleviate many of the symptoms associated with the disproportionately large breasts.
Patients considering breast reduction surgery should also consider the potential downsides (risks/complications) associated with the procedure as well.. Poor scarring, for example may be associated with the procedure. 

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 “C 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.
Best wishes with your breast reduction procedure; hopefully you will be very pleased with the outcome of the procedure performed.

It's impossible to say with the final cup size would be but 500 cc@of each breast is a relatively modest reduction for someone as large as you describe. Make certain your plastic surgeon understands where you want to end up.
