What would my predicted cup size be after having 400 grams removed from each breast (34J)?

Question

I am 5’6, 160 lbs, and I wear a 34J bra. If I have 400 grams removed from each breast, what would my predicted new bra size be? I understand breast density and other factors play a role. Is band size a factor when determining approx how many grams are in a cup size? Sorry, I hope this makes sense! Any feedback would be great!

Patients often think in terms of cup size. Reductions are measured in weight/gms.

Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.

The average reduction is approximately 500 gms/side. This will represent a different size change on different patients/breasts.

When planning a medical reduction, the weight is the primary goal with the volume/cup size being secondary. Alternatively, a cosmetic reduction will focus primarily on volume without consideration of weight or density.

With regards to your specific question, 400 gms is fairly conservative given a large J cup size. Unless there is very little volume or glandular density, I would not expect dramatic cup size change post op (i.e. J to C).

As always, discuss your concerns with a board certified plastic surgeon (ABPS).

This is a tricky question as bra sizes can vary greatly from one manufacturer to the next.  Having 400g of tissue removed will reduce your breasts multiple cup sizes.  I encourage you to speak with your surgeon who will be able to offer more information after an examination.

We found that patients are better guided by proportions, rather than weight and cup sizes. It may help you, finding pictures of patients with a similar body frame and the breast size you are aiming for. This information might be more helpful during your consultation with your plastic surgeon. The actual numbers are then secondary. I hope this helps.

Dear Joyful13,

it is hard to tell for sure without an examination. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

At size 34, each 100 grams removed corresponds to 1 cup size change.  If 400 grams are removed then you will go down 4 cup sizes to a 34 F.
