32G, removing 370 grams of breast tissue. What size will I be looking at?

Very difficult to know without photos.  What I can tell you is that the size of your breasts will continue to go down over several months after surgery as some of the fat gets resorbed.  Because of this, I usually try to leave the breasts on the full side, realizing the size will continue to go down after surgery..

370 grams is not that significant if you are currently a G. This may bring you down a cup size or two.  It is difficult to assess without images.   I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery, a member of the American Society of Plastic Surgery (ASPS) and the American Society of Aesthetic Plastic Surgery (ASAPS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach Trained, Double-Board Certified Plastic Surgeon

will end up with still very generous cup sizes... and speculating without seeing you or having the benefit of knowing how dense your tissue is, would expect you to still be a DD+ size.  Your surgeon should be able to give you some idea of what you will be like but realize no surgeon can guarantee what cup size you will be following a reduction.  Minimal excision = minimal reduction.

Hi and thanks for your question. Yes you're right this is a difficult question as it's virtually impossible to predict cup size based upon the amount of tissue which is removed at the time of breast reduction. There are many reasons why no one can predict your ultimate bra size not the least of these being that cup size isn't standardized within the beauty industry nor medical field. Patients are often frustrated that different retail stores size them very differently where one shop might size you a D and another a C cup. This is also the case in surgery as many variables determine final "cup size" some of which are beyond the control of your plastic surgeon. See an experienced breast surgeon who is certified by the American Board of Plastic Surgery. After decades in practice, that's the best advice I can offer you. 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. Having said that, given your current cup size, I would consider 370 grams a relatively small reduction.
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 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. 
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. You may find the attached link, video helpful to you as you learn more.Best wishes; hopefully you will be very pleased with the outcome of the procedure performed.

Typically 300grams of tissue will reduce you by 2 sizes at the volumes that you are considering when undergoing breast reduction, but there is great patient variability and a consultation by a board certified plastic surgeon is necessary to provide you a definitive recommendation.
