Breast Fat Transfer

Breast Fat Grafting San FranciscoSan Francisco Fat Transfer to Breasts

Not every woman wants to have breast implants if they are unhappy with the size and/or shape of their breasts. Newer techniques have helped to refine a process called fat grafting where fat is removed from one part of the body and placed into another. It is used to enhance the size and shape of the breasts and buttocks and is also commonly used for facial rejuvenation in place of fillers. Fat transfer can also be used to help correct subtle breast asymmetry and may be used as an adjunct to breast augmentation. An additional benefit is that liposuction needs to be performed to harvest the fat, allowing you to remove fat from stubborn areas. Having your own fat instead of an implant is very important to many women and is possible at Sieber Plastic Surgery.

Dr. David Sieber will be able to assess how much fat you have available to transfer as well as how much fat your tissue will be able to accept. Dr. Sieber has published many journal articles on advanced techniques in fat transfer and uses his advanced training in cosmetic surgery to deliver consistent and reliable results.

Fat Transfer Improvements

Fat transfer is ideal for improving:

  • Hypomastia (small breasts)
  • Breast asymmetry (one breast larger than the other)
  • Loss of volume in breasts
  • Thickness of soft tissue coverage of breast implants

Fat Transfer Technique

Dr. Sieber will see you in the preoperative area and will mark the areas on your body from which you want the fat removed. The areas typically harvested are the arms, abdomen, flank, back, and/or thighs. A small incision is made in the marked areas and a saline solution is injected into the area to help with bruising and to make harvest of the fat easier. Once the fat has been removed and the area has a smooth contour, the fat is then reinjected into the breast through a small incision using a small metal tube. Dr. Sieber will have told you prior to surgery about how much fat he thinks will fit into your breasts. Once the ideal size and shape has been achieved, the small incisions are closed.

Depending on the final desired size, some women may require multiple sessions in order to achieve their ideal results.

Preparing for Fat Transfer Surgery

As with any major surgery, all medications and supplements which cause an increased risk of bleeding should be stopped 2 weeks prior to surgery. Please see our list of medications and supplements to avoid. As always, make sure to check with your doctor before stopping any medications.

Recovery from Fat Transfer Surgery

Swelling and bruising are very common after surgery and will slowly resolve over the first 2-3 weeks. You will also experience some discomfort, swelling, and bruising around where the fat was harvested. Most patients take 3 to 5 days off from work to recover after surgery.

You will be required to wear a compression garment over the areas which had liposuction for the first 2 weeks after surgery. For the next 10 weeks after that Dr. Sieber will have you wear compressive clothing such as Spanx to help reduce the swelling and to maximize your result.

After surgery, you will need to refrain from any rigorous activity for the first 2 weeks, and avoid lifting anything heavier than 10 lbs. After that point, you may gradually increase your activity level. Listen to your body and if it feels like you are overdoing it, then scale your activity back some.


Q: I want to increase 2 cup sizes but don’t want implants, is fat transfer a good option for me?

A: The increases in breast size with fat transfer tend to be subtler. There is a limitation with how much fat can be transferred depending on how tight your breast tissue is and how much fat you have available for the procedure.

Q: I have saggy breasts, will fat transfer help lift my breasts?

A: Fat transfer will not help lift your breast tissue. Dr. Sieber will be able to tell you during the consultation whether or not fat transfer is able to meet your goals for surgery.

Q: How much of the fat transferred stays?

A: Typically after any fat transfer procedure 50-75% of the fat remains in the long term. Some patients who desire a larger increase in breast size may require multiple procedures to obtain their goals.

I couldn’t be more pleased and excited about the refresh Dr. Sieber did on my face using a combination of botox and fillers. I had a baby a year ago and my face looked completely deflated. It felt to me that I looked like I had aged 5 years instantly by having a baby over 40. Dr. Sieber looked closely at my face and listened to my desires and fears in terms of the results I was seeking. I really liked that he took a conservative approach and followed up to check in and tweak things once the fillers and I had time to settle in.*

Dr. Sieber is a caring, friendly and talented doctor. I had two long consultations (free of charge) before scheduling my BBL (Brazilian butt lift). The staff and Dr. Sieber made me feel calm and relaxed the day of surgery. The results are amazing. Dr. Sieber understands a woman’s body and totally changed the shape of mine. I could not recommend him highly enough. I now go to him for my Botox and Juvederm.*

Dr. Sieber was fantastic throughout the entire process. From the beginning, he was patient with my questions and never made me feel pressured about making a decision. Once deciding that I was going to move forward with a breast augmentation, he made sure that I understood the process of the procedure and what I could expect post-surgery. I could not be happier with the results!*

Dr. Sieber is the best. I interviewed with numerous doctors. He pays close attention to detail. He called and checked on me and my results on a regular basis. My tummy procedure exceeded my expectation.*

Dr Sieber was very kind, knowledgeable and patient. He was able to answer all of my questions and put me completely at ease during the consultation as well as during the actual procedure. He made sure that I understood each part of the process which went a long way in alleviating my fears…after all, this is my face!*

Dr. Sieber is attentive, responsive, and well trained. I had seen him for Botox and filler and he had done both without any pain or bruising and more importantly the results were fabulous. He has met with me on time at each appointment. He communicates what to expect, made sure I was comfortable throughout the procedure, checked on my healing every day post procedure. He couldn’t be more delightful not more talented. I had seen other plastic surgeons for in office treatments over the past decade and Dr. Sieber is at the top of the list in terms of delivering the desired outcome and high quality care.*
