Breast cancer reconstruction is a deeply personal surgical journey that restores not just the physical appearance of the breast, but also a woman’s sense of wholeness and confidence after having mastectomy or lumpectomy as cancer treatment. At our San Francisco Plastic Surgery practice, we understand that breast reconstruction is far more than a technical procedure, it is an opportunity to help you reclaim your body image and move forward with renewed self-assurance.
For some women, however, the breast reconstruction process does not end with the initial surgery. Over time, changes in the body, healing challenges, long-term radiation effects or dissatisfaction with prior results may lead patients to seek revision after breast reconstruction. Dr. Karen Horton specializes in helping women refine, correct, or improve previous reconstruction outcomes with a thoughtful, individualized approach.
Revision after breast reconstruction refers to surgical procedures performed to improve the appearance, symmetry, comfort, or long-term results of a prior breast reconstruction. These procedures may be performed months or even years after the original surgery.
The goal of revision surgery is not simply correction, but optimization—helping patients achieve a result that feels more natural, balanced with their body, and aligned with their expectations for their breasts.
Depending on your prior breast reconstruction method, revision may involve implant-based techniques, autologous (flap) adjustments, scar revisions, or a combination of approaches tailored to your personal preferences, anatomy and surgical history.1
The decision to pursue breast reconstruction revision surgery is highly personal and often multifactorial. While many women are satisfied with their initial reconstruction, others find that their results evolve over time or do not fully meet their expectations. Studies have shown that elective revision procedures are a common part of the reconstruction process for many patients.2
Patients may consider revision to address:
Beyond physical improvements, revision procedures can also provide meaningful emotional benefits. Many patients report feeling more comfortable in clothing, more confident in their appearance, and more at ease in their day-to-day lives after refinement of their reconstruction results.
Dr. Horton frequently works with patients seeking correction of complex or nuanced concerns following prior reconstruction, including:
Each revision plan is highly individualized, taking into account your surgical history, current anatomy, and long-term goals.
"Dear Dr. Horton, Way back in April 2011 you reconstructed my right breast after I had lived with wearing a breast insert for over fifteen years. I can't tell you what a difference you made in my life, and I'm sorry for not writing this sooner! The hospital experience was so great, even though the recovery was rather a lot. But it was all so worth it and your meticulous work left me feeling complete and back to "normal" in a way I couldn't have anticipated. Wearing a bathing suit, "normal" clothes and moving freely are all so great and I still feel grateful to you every time I see myself naked in the mirror. The symmetry is truly a work of art! With so much gratitude, L."
„Revision surgery may involve a range of techniques depending on your needs:
Dr. Horton’s advanced microsurgical training allows her to address even complex revision cases with expert precision and careful planning.
As a breast cancer survivor, Dr. Horton helped ease my transition to the 'new normal' with a beautiful new breast. She is a caring woman and skilled artist. I am whole again.
„Breast reconstruction is not always a one-time procedure. Over time, natural aging, weight fluctuations, implant lifespan, and the effects of prior treatments such as radiation can influence results.
Revision surgery offers an opportunity to refine these changes and maintain long-term aesthetic balance and comfort.
In this video, Dr. Horton’s patient, Allison, discusses her choice to undergo reconstructive surgery after breast cancer treatment. She touches upon life before and after the surgery, and how she is able to do everything now that she could do before having the procedure with a renewed feeling of confidence.
Revision after breast reconstruction requires a highly personalized and thoughtful approach. During your consultation, Dr. Horton will:

I can only say Dr Horton completely changed my life. I had numerous unsuccessful surgeries before finally meeting Dr Horton. I was a 2 time cancer survivor and the radiation from my initial diagnosis had caused substantial damage and made reconstruction very difficult. I had unsuccessful breast reconstruction after my bilateral mastectomy at UCSF. She patiently talked to me about options and gave me the bad news that my body would need to heal for a year from the ongoing infection I had from my surgeries with my prior doctor. She told me what I needed to hear, not what I wanted to hear. I had numerous stages to my reconstruction. Dr Horton and I talked about how there would be a number of steps needed, for my initial surgery with her I underwent a free flap surgery. She was with me every step of the way. She gave me her cell phone number and called me immediately if I texted or left a message. She was always there to assure me when I was concerned. I am sad to see the negative comments. I am confident that Dr Horton never told anyone that all they would need is one surgery. No doctor can guarantee results nor outcomes. Every person is different and their bodies respond differently. I had to have additional surgeries due to healing issues which had nothing to do with Dr Horton, it was my body responding and it was still struggling with the radiation after effects. I also had implants put in under the flaps in a secondary surgery due to issues with my breast bone. ( again my body issue, not Dr Horton) She gave me a “makeover” and I am so happy with the outcome. I look and feel better than I have in 20 years! I sent one of my best friends to Dr Horton when she was diagnosed with Breast Cancer. She loved Dr Horton and had the same amazing experience that I did. The preponderance of comments are positive and reflect who Dr Horton really is. I have, and will continue, to recommend her. She is truly the best.
At the age of 35, I was diagnosed with HER-2 positive breast cancer. It was both frightening and devastating. Although I received treatment at UCSF, I wanted a private surgeon for my bi-lateral mastectomy. The decision to have a mastectomy over a lumpectomy was a fairly easy one for me as my mother had breast cancer and I'm aware the younger you are, the longer you have to go without recurrence. I had my work cut out for me when looking into which plastic surgeon to go with. I work for a data and security company and research is one of my main strengths. I went to 6 plastic surgeons in San Francisco, Marin County and in the Stanford/Palo Alto area. I cross examined them and came to the conclusion that Dr. Horton would be my plastic surgeon. I preferred the implant to be over the muscle as I'm very athletic and didn't want to lose any upper body strength. I also didn't want the flex seen when the implant is put under the muscle.The first part of the mastectomy was done in Feb 2017 when the tissue expanders were put into place. I then saw Dr. Horton 6-7 more times before the second surgery for the final implants in August 2017. The whole procedure could not have gone better. The results are beautiful. Dr. Karen Horton was amazing to work with and I would highly recommend her to anyone who wants great results while going through the (unfortunate) process of a bi-lateral mastectomy and reconstruction.Of all of the doctors who assisted during my breast cancer journey, Dr. Horton was one of the best. She was a true advocate and I can say that the breast cancer did not get the final say on how I feel about myself as a woman and as a survivor. I feel great today about my breasts and I hope other women are given the same opportunity I was in finding the right providers.
How common is revision after breast reconstruction?
Revision procedures are relatively common. Many patients undergo one or more additional procedures to refine symmetry, address changes over time, or improve overall results.
How long should I wait before having revision surgery?
Timing depends on your prior surgery, healing, and any additional treatments such as radiation therapy or breast skin removal from cancer treatment. In many cases, patients wait several months to a year or more before pursuing a revision from their last surgery.
Can revision surgery improve symmetry?
Yes. One of the primary goals of revision is to improve balance between the breasts, whether through adjustments to the reconstructed breast(s), the natural breast, or both.
Will I need implants replaced during revision?
Not always. Some revisions involve repositioning or refining existing implants, while others may include implant exchange depending on your goals and any implant-related concerns.
Can I switch from implants to a natural tissue reconstruction?
In some cases, yes. Patients who are not satisfied with implant-based reconstruction may be candidates for conversion to autologous (flap) reconstruction.
Is revision surgery more complicated than the original reconstruction?
Revision procedures can be more complex due to prior surgery and scar tissue. This is why choosing an experienced, Board-Certified Plastic Surgeon with expertise in revision is especially important.
Thank you so much for the support and care you have provided me. All of you are wonderful angels in the darkness that is BRCA/breast cancer.
