I want to downsize my breast implant. Would 50 or 75 cc make much of a difference? (Photo)

Going down 75 cc would make a subtle difference, probably less than 1/2 cup size.  But I would recommend waiting until you are at least 6 months and maybe even a year after your surgery.  Your perception and happiness with your size may change over time.  Fortunately, if you do decide to switch implants it is a easy procedure to have done.  Good luck.

You
state that your breasts make look heavy. 
That is because your breasts are too low and augmented.  The preferred technique for you would have
been a breast lift.  Women hate breast
lifts because of the vertical scars associated with the traditional
technique.  I recommend explantation using
The Bellesoma Method.  Your breast tissue
is reshaped creating upper pole fullness without implants, elevated higher on
the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation
and the ability to breast feed are maintained, if not injured from your
previous surgery.  At the same time or
later, fat transfers can be performed if additional volume is desired.Best Wishes,Gary Horndeski, M.D. 

Hello,NOBODY can predict what cup size anyone might be, whether it is a primary breast augmentation, a revision to go smaller, or a revision to go bigger. That's because there is no correlation between implants and cups.  Instead of planning on a cup size, had you and your surgeon sized in the office using sizers, an unpadded bra, a few favorite tops, and a mirror, you would likely be happy today. Going down 75 cc from a 375 cc and 350 cc implant is only a 15% and 20% reduction, respectively; both too little to make a visual difference. Best of luck!

50cc is 3 tablespoons and 1 teaspoon of volume, and makes a barely-perceptible change that in my opinion is not worth the cost (and slight risk) of the surgery. 75cc will make a visible difference, but a subtle one. If you're buying new implants anyway, I would consider going to a moderate plus rather than a high profile implant, which will also help your "stick out way too much" appearance. The combination of both size and profile change will make all the difference, and will significantly diminish your concerns. You won't go down a full cup size with 75cc, but with size plus projection change, I believe your look will be excellent, and you will not require or benefit from a lift.Please also realize that every patient is her own worst critic--no one else will look at you and say anything but "Wow; you look fabulous, dahling!" Also, healing, settling, and softening are not complete until 6-12 months post-op. Let this time pass to both to see how things change further before you decide exactly what you want, and how you feel about your look then. In the meantime, do not stress over this--you DO look great and should enjoy it, even if you do decide to tweak things down the road. Best wishes! Dr. Tholen

will make a difference, likely NOT a cup size difference like your talking, challenging thing is dropping down 100cc you will have to also change profiles most likely, which may not give you the "look" you are trying to achieve. Go back to your surgeon and have a discussion about your goals

A few thoughts come to mind while reading your question.  First, bra manufacturers do not have standard cup sizes so no one can guarantee you a particular cup size.  It all depends on where you buy your bras.  Second, you did not mention whether you have high profile, moderate plus profile, or moderate profile implants.  You mentioned that you thought they "stick out" too much.  Perhaps just changing to a different style but keeping the same volume would help.  Finally, 50 - 75 cc's is not a large amount.  My father had a rule of thumb that a cup size was roughly 150 -200 cc's.  While that may have changed somewhat over time, I think that you might need to go a little bit smaller than 50 - 75 cc's if you want to see a noticeable difference in size.  Your best bet is to meet with a board-certified plastic surgeon who can examine you in person and review your options with you.

It's unfortunate that you did not make these decisions before your surgery. I suggest that you confer with your Operating Surgeon and determine your best options. With your height and weight 75cc may produce your intended change. Keep in mind - you may eventually need a lift to achieve your goals.

It has only been three months since your breast implant surgery was done. You still have some swelling, so I recommend that you wait another three or four months to see how you like them when all of the postoperative swelling has subsided, an d your tissues have relaxed.
To answer your question directly, 75 mL would make a noticeable difference, but it would not be worth the extra surgery to reduce by 50 mL in my opinion. It generally takes from 25 to 40 mL to even tell a difference.
Thank you for your question and photographs, and good luck.

In general, if you are trying to go down a cup size or more I would reduce the implant size by 100 cc or more, taking into account your breast width and dimension.   Decreasing the size of the implant also decreases its weight and may let your breast tissue retract a little on its own.

You might want to consider going down 100-125 cc's, with a lower profile implant. I would suggest going back to your surgeon and discussing your options.
