I have 36-B breasts and would like them a bit larger. It seems 50cc would increase my size to a full B wouldn't it?

Increasing by only 50ccs will only minimally increase your size.  You may not even notice the change.  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 (ABPS), a member of the American Society of Plastic Surgery (ASPS), a member of the American Society of Aesthetic Plastic Surgery (ASAPS), and a fellow of the American College of Surgeons (FACS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach TrainedDouble Board-Certified, Double Fellowship-Trained Beverly Hills Plastic Surgeon

HI I am Dr. Lane Smith from Las Vegas Nevada.   As you would imagine practicing in Las Vegas, I do a lot of breast augmentations.  50 cc is slightly less than two ounces of fluid or about 3 tablespoons.  Usually that amount of increase is barely noticeable.  When patients come to me for a bigger size, the smallest change I recommend where they can actually see a difference is about 75 cc's.   I would recommend you go at least that if you are thinking of changing your size.   I hope this is helpful, Lane Smith, Board certified plastic surgeon

Dear Michaell,Determining the ideal breast size and matching that goal for the patient is the most difficult part of breast augmentation. It starts and ends with the patient. We have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements. Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If its too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match. Of all of my breast augmentation patients, everyone of them have been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.Daniel Barrett, MD, MHA, MS

The results of fat grafting depends on the amount of fat available to be harvested and breast volume to be grafted.  Please see the link

The rule of thumb is that for every 150 - 200 cc you increase by 1 cup size. This varies depending on your tissue dynamics and size. Also about 70% of the fat will stay by about 6 months post op and that is pretty much there forever. So considering all these variables you can see why it is best to have an in person consultation rather than calculating how much fat you need. Sometimes 3D reconstruction during consultation can help. 

Hi and thanks for the question. In general, you'll need no less than 100 ccs of viable fat transferred per side to translate into an increase in one cup size.  The cost will depend on how much harvestable fat you have, which will accordingly determine the operative time and associated costs.  In my practice, I offer services / techniques to optimize the amount of fat that "takes" by utilizing the Pure Graft fat purification system. Post-surgically I also advise my patients to undergo a series of hyperbaric oxygen treatments - this, in my experience, reduces the recovery period and produces optimal results in terms of the amount of viable fat that survives following transfer.Warmest Regards,Doctor Vallecillos, MD, FACS, Diplomate, American Board of Plastic Surgery 

Generally speaking it can take around 100ccs to go from a the smallest B to a full B. Since some fat is absorbed or lost during fat grafting, that would mean you may anticipate needing up to 125 to 200cc of fat injected into each breast to achieve your goal. Cost will vary depending on the the duration of the surgery and type of equipment used for your fat grafting. It is best to get some complimentary estimates during some in-office evaluations before making your final decision. Hope this helps!Johnson C. Lee, MD Plastic Surgery@drjohnsonlee

due to the unpredictability of your graft take/survival.  You must always graft  more as there is never 100% survival.  Costs will vary widely from surgeon to surgeon but in my practice, you are looking at $1500 plus and if you have a liposuction procedure (assuming you would benefit from it), costs will start at $2500.  An exam is necessary to provide reliable cost estimates so schedule consultations with surgeons in your neighborhood and choose what is best for you.

Hi Michaell:It generally takes 200 cc of volume to increase your breasts by 1 full cup size assuming you are of a 34 inch bra size. For you to increase to a full B with 60cc of fat, you would almost need to be of a full B size to start. Assuming that you are favoring fat injection for breast enlargement, the surgeon will need to inject approximately 120cc of fat per breast since about 1/2 of the fat is absorbed by the body. Whether or not your breasts would be loose enough to accept that amount is something to discuss with your plastic surgeon during your consult. At the time of the consult you would also be able to try on sizers to make sure that 60cc is the amount you would need to achieve your desired full B cup size. You may also want to bring nude breast photos with you to the consult showing your desired look.With Warmest Regards,George Sanders, M.D.
