Women undergoing mastectomy as part of treatment for breast cancer not only have to cope with a cancer diagnosis and treatment but the decision of whether to have breast reconstructive surgery. Both options — implant surgery and flap surgery (in which the surgeon uses the patient’s own tissue to reconstruct the breast) — can provide excellent cosmetic results, but it’s important to make the decision in close collaboration with your surgeon.
- The goal of reconstruction is to restore the breast mound and achieve symmetry.
- Implant and flap surgery are the two major types of breast reconstruction.
- Flaps make use of a woman’s own tissue to reconstruct the breast.
- Flaps offer a larger, softer breast.
- The best candidates for implants tend to be smaller, thinner women.
A diagnosis of breast cancer can be terrifying enough. Finding out that mastectomy (surgery to remove one or both breasts) is required to treat the cancer can compound the devastation. For some women, the feelings surrounding the loss of one or both breasts can be nearly as overwhelming as the cancer diagnosis itself.
While there’s no procedure that can restore feeling in the breast region after a mastectomy, recent advances have expanded the range of reconstruction options available to women today. Patients can get excellent cosmetic results whether they choose to have the procedure done with implants or using their own tissue, generally known as flap surgery.
At Memorial Sloan Kettering, our plastic surgeons are working tirelessly to refine reconstruction options, and many of them are innovators in the field. Establishing good communication with patients is key to their success. To help you better understand your options, we spoke with Peter Cordeiro, Chief of the Plastic and Reconstructive Surgical Service, whose work has contributed to a number of improvements in breast reconstruction and microsurgery.
What is the goal of breast reconstruction, and what factors do you take into consideration when making a recommendation?
The goal of breast reconstruction after mastectomy [the removal of a breast] is to restore the breast mound, or mounds, and achieve symmetry. At MSK, breast surgeons [who perform mastectomies] and plastic surgeons [who reconstruct breasts] work closely with medical oncologists, radiation oncologists, and with the patients themselves to develop the optimal surgical treatment and a reconstruction strategy.
The type of breast cancer a patient has — including its location within the breast and the stage of the cancer — her body type, general health status, what additional therapy she may need either before or after surgery, as well as her own wishes regarding the type of surgery she may want are all factors in the recommendations I make to my patients.Back to top
Tell us about implants, since that’s the type of breast reconstruction most of us are familiar with. What does that procedure entail?
The implant is the most common form of breast reconstruction, and it involves the use of either a silicone or a saline implant to rebuild the breast. At MSK, we most commonly use silicone because it’s softer and feels more like a natural breast.
For the vast majority of our patients, implant surgery involves two steps. First, at the time of mastectomy, we place a tissue expander underneath the pectoralis muscle in the chest. After a couple of weeks — once things start to heal — we slowly fill the expander with saline so that the muscle and skin gradually stretch out. On average, the expansion process takes around six to eight weeks. Then, after another six to eight weeks, we remove the expander and put the final implant in its place.Back to top
Is there an ideal candidate for implants?
The best candidates for implants tend to be smaller, thinner women with a B cup breast. Fuller-breasted women can have implant reconstruction, but if they received a unilateral mastectomy [when one breast is removed], we would need to do a reduction on the natural breast in order to achieve symmetry with the implant. Similarly, for women with an A cup breast size, we may need to do a breast augmentation of the natural breast to achieve symmetry.
Implants can occasionally leak or get infected, which may require another procedure down the line. However, implants do provide very good results and are a great option for many women.Back to top
And what about the second option, flap reconstruction? What does that involve?
Flap reconstruction makes use of a woman’s own tissue — including skin, fat, and occasionally muscle — to reconstruct the breast. That tissue and skin can be obtained from a variety of places, and the area and method we choose will depend on factors such as the amount and quality of tissue available as well as the patient’s preference.
TRAM flap reconstruction, the most common of these methods, involves using tissue from the area below the belly button. The skin, fat, and at least one abdominal muscle are tunneled underneath the skin upward into the breast area but remain attached to their blood vessels in the abdomen. This allows the transferred tissue to continue to get its blood supply from where it originated, making it the simplest of the flap procedures. The downside is that it requires sacrificing muscle, which potentially can affect function in the abdominal region.
At MSK, our overall approach is to sacrifice the least amount of abdominal muscle possible, or in some cases no muscle at all, and we can do that using two newer reconstructive techniques — the free TRAM flap and DIEP flap. These procedures involve the relocation not only of tissue but also of the tissue’s blood supply, which means that microvascular surgery techniques are required to complete them. [Microvascular surgery refers to surgery that’s performed on very small blood vessels using an operating-room microscope and a variety of tiny, special instruments.] In a free TRAM flap, very little muscle is removed, and in DIEP flap the entire abdominal muscle can be spared.
Aside from the abdomen, other areas that often have a lot of tissue are the thighs and the buttocks. The TUG and DUG flaps utilize skin, fat, and a small piece of muscle from the thigh to reconstruct the breast. The gluteus flap utilizes the buttock as a source of skin and fat for breast reconstruction.Back to top
What are the benefits of using your own tissue?
Using your own tissue makes for the most natural-feeling breast. So if you want a larger, softer breast, a flap is a very good choice. That’s the main benefit. With flaps, the newly reconstructed breasts tend to age the same way as a natural breast. You obviously have to have enough tissue available to donate, whether it’s from your abdomen, thigh, or buttock. For women who are too thin, implants are a great alternative.Back to top
What are the risks or downsides to flap surgery?
It takes longer — doing a flap will often add three to eight hours to a mastectomy, whereas an implant usually adds only about 45 minutes. The main downside of doing a flap is the potential impact it has on the area you’re taking the tissue from. If muscle is removed, you risk compromising the affected area.Back to top
What factors might prohibit reconstructive breast surgery?
As a general rule, we at MSK like to consider all patients as potential candidates for breast reconstruction surgery. The ones who aren’t candidates tend to be patients with very advanced disease or those who are very elderly.Back to top
One last question: When is the best time for breast reconstruction — at the time of a mastectomy or afterwards?
We generally recommend reconstruction at the time of mastectomy, unless there are some special circumstances. This allows women to get back to their normal life as quickly as possible. It also spares them from having to undergo a second operation. That said, we see patients at all stages, including women having prophylactic mastectomies or who underwent mastectomy at other hospitals and are now reconsidering their original decision not to have reconstruction.Back to top
