A Mayo Clinic Division of Breast and Melanoma Surgical Oncology team performs a procedure.

The Division of Breast and Melanoma Surgical Oncology (BMSO) at Mayo Clinic's campus in Rochester, Minnesota, centers around an experienced group of fellowship-trained surgeons who perform more than 1,200 operations annually. The BMSO team includes surgeons, nurse practitioners, nurses and support staff exclusively dedicated to the management of patients with breast and skin cancer, benign breast disease, and elevated risk of developing cancer. The team is internationally recognized for its performance of complex procedures with safe and excellent outcomes.

Mayo Clinic breast and melanoma surgeons practice in an atmosphere of inquiry and innovation, continually evolving and improving their high-volume surgical practice. The surgeons are involved in research from basic science to clinical trials to develop and evaluate novel approaches for patients with breast and skin cancer.

Integrated, multidisciplinary clinical and research practice

In addition, surgeons within the division are also career researchers. They conduct research in basic and translational science, clinical trials for novel therapies and surgical techniques, and quality improvement to continually advance patient care.

The melanoma program shows the benefits of this approach. It leverages the latest science and care practices, relying on precise diagnosis, skilled surgical excision and the latest immunotherapies. Physician-scientists collaborate on patient care, innovative research and diagnostic excellence to provide highly individualized melanoma care, and our teams share this expertise with other medical professionals regularly.

Innovative techniques

Early and recognized experience in nipple-sparing mastectomy

Mayo Clinic surgeons were one of the earliest groups performing nipple-sparing mastectomy, and they have been doing so for more than 15 years. Combined with immediate reconstruction, it offers a woman a more natural appearance following mastectomy without diminishing cancer treatment outcomes.

Intraoperative frozen section pathology for all breast surgeries

Surgeons review intraoperative frozen section scans during surgery.

Mayo Clinic is one of the only medical centers in the nation to use intraoperative frozen section evaluation for all breast surgeries, which lets pathologists rapidly analyze and diagnose tissue samples while the patient is still in the operating room. This ensures that cancer is entirely removed during the procedure and minimizes the need for subsequent operations, which saves patients from added time, expense and stress.

Frozen Section and Sentinel Lymph Node Biopsy — Mayo Clinic

Judy C. Boughey, M.D., Breast/Melanoma Surgery, Mayo Clinic: When surgical resection of breast tissue occurs, pathological evaluation -- the review of the tissue under a microscope -- is a critical component to optimal patient care. While pathologic information can take days or weeks to obtain, at Mayo Clinic this tissue is evaluated by our pathologists while you are asleep in the operating room using an immediate frozen section method.

Frozen section analysis provides benefits on multiple levels. For patients undergoing excisional biopsy of benign breast lesions, it allows intraoperative confirmation that the tissue removed was benign. Importantly, for those cases where an unexpected malignancy is identified, this information can be given to the surgeon during the operation so that additional margins can be resected if necessary. This also means that the patients and her family can be informed by the surgeon about the pathologic findings on the day of surgery, and additional consultations or procedures planned, as needed.

For patients undergoing preventative or prophylactic mastectomy to decrease the long-term risk of breast cancer development, an unexpected cancer is identified in just a few percent of cases. In our practice, we routinely prepare for that possibility with the injection of a radioactive tracer in the breast that is undergoing preventative mastectomy. Once the breast is removed the pathologist evaluates the tissue. In cases where no cancer is identified, no lymph nodes are removed. If a hidden (or occult) cancer is identified, the surgeon proceeds with sentinel lymph node surgery. This preparation helps avoid the potential need for a second operation in the setting of a surprise finding of cancer.

This immediate and close collaboration between the breast surgeons and the pathologists for each individual minimizes the need for further operations and also decreases the waiting time for patients to find out the pathology from the surgical procedure.

Personalized care, rapidly tailored to your needs

Our multidisciplinary team model lets us leverage recent breast cancer treatment advances to develop a personalized comprehensive treatment plan.

A surgeon and care team member discuss aspects of a care plan.

For example, our approach to lymph node surgery for newly diagnosed breast cancer is to first ensure we stage the disease accurately, and based on that, provide you with the best treatment plan.

  • We assess the lymph glands under the arm using what's called an axillary ultrasound, and also possibly from a small needle biopsy. Based on what we learn there, we can adapt your course of care. When appropriate, we can further assess the involvement of any disease cells with a dual-tracer dye sentinel node biopsy.
  • The information we gain about lymph node status combined with frozen section pathology consultation lets your surgical team adapt even during the course of a procedure. This allows the team to take the right action to ensure the disease is properly addressed, but also perform no more invasive surgery than you need.
  • For patients treated with systemic therapy first, based on the response of the tumor to the therapy received prior to surgery, we tailor the surgery to the extent of remaining disease, allowing us to de-escalate treatment and minimize use of invasive procedures.

Sentinel Lymph Node & Axillary Lymph Node Procedures for Breast Cancer at Mayo Clinic

Tina J. Hieken, M.D., Breast/Melanoma Surgery, Mayo Clinic: Hi, I'm Tina Hieken. I'm a surgical oncologist and an associate professor of surgery, and one of the breast surgeons here at Mayo Clinic in Rochester. Today I'd like to talk with you about lymph node surgery that's done for women with newly diagnosed breast cancer. Sometimes the lymph node surgery is the part of breast cancer treatment that women have the greatest fears and concerns about. One of the reasons that we evaluate lymph nodes for women with newly diagnosed breast cancer is to make sure that we stage the disease accurately, and that we provide you with the best treatment.

Our first step in our practice here in looking at lymph nodes is to do an axillary ultrasound. So we look at the lymph glands under the arm but we call the axillary lymph nodes using an ultrasound probe. For women who don't have lymph nodes that are enlarged that we can feel, most of the time when they have the lymph node ultrasound, the nodes will be normal but sometimes they will look abnormal. In those cases, we have you get a little needle biopsy of those lymph nodes so we know about them ahead of time. For those cases where the lymph nodes are normal -- and that's most women -- the next step is to discuss with you what we do from a surgical standpoint to manage the lymph nodes. For most women with normal lymph nodes under the arm and normal lymph nodes on the ultrasound, what we recommend to stage the lymph nodes and treat them is to do a sentinel lymph node biopsy. This involves getting an injection into the breast of a tracer done prior to surgery, and then at the time of operation, an injection of a blue dye that's done while you're asleep. This dual tracer method allows us to be really accurate. Those tracers actually trace out where cells might leave from the breast into the lymph glands if they were to travel from the primary breast tumor into the lymph nodes under the arm. Then in operation, we remove those lymph nodes -- usually we remove one or two or three; sometimes more -- and give them to the pathologist.

There's been some recent studies that have suggested that for some women who undergo breast conserving treatment (a lumpectomy) along with the sentinel lymph node biopsy, especially women with small tumors, especially women whose tumors are estrogen receptor-positive and women who plan to have radiation to the whole breast after their lumpectomy that we don't need to take out more lymph nodes from under the arm if there is a very small amount of cancer in only one or two lymph nodes.

Usually we remove two or three sentinel lymph nodes at the time of operation; sometimes we only find one and sometimes we may remove five or six or more. Usually we have this information about the lymph node status at the time of operation and the pathologist lets us know not only the number of involved nodes but the size and the extent of the nodal involvement. Sometimes, however, we think that everything is fine on the day of operation and we receive that information only when the pathologists review the permanent sections where they look in greater detail at the lymph nodes that we've removed at operation. If they find only a little bit of cancer in one or two lymph nodes, it's unlikely that we would recommend that you come back and at a second operation have surgery to remove more lymph nodes from under the arm; however, sometimes they may find lymph nodes that are large in size, that have large size metastasis in them, or ... when the cancer has spread outside of the lymph nodes that may make us want to make a recommendation to do more surgery. We would discuss the risks and benefits of axillary lymph node dissection in a second operation with you and make a decision about how best to proceed.

When the pathologist finds only a few abnormal cells or small clusters of cells in the lymph node, then we might not want to take more lymph nodes out from under the arm. However, sometimes when the pathologist finds either a large size lymph node metastasis or multiple nodes, or lymph nodes with spread of the cancer outside of the capsule of the lymph node, we may wish to take more lymph nodes from under the arm. What happens if we do this? Well the complications that can occur with either a sentinel lymph node biopsy or a lymph node dissection are pretty similar. The most common complication is numbness under the arm in the inner upper arm after surgery that sometimes goes away but sometimes persists, and the most feared complication is swelling of the arm; that can be swelling in the hand, the forearm, the arm, or even in the tissues of the breast or the chest wall.

One recent study that looked at sentinel lymph node biopsy patients and patients who had a sentinel lymph node biopsy followed by an axillary lymph node dissection found that the percentage of women who had swelling of the arm or lymphedema three years after surgery was about 14% in the women who needed more lymph nodes taken out -- so a sentinel lymph node biopsy and an axillary dissection -- and about 7% in the women who had a sentinel lymph node biopsy alone. There are some things that we do from a technical standpoint to minimize the risk that you will develop lymphedema.

It's really encouraging that we have made so many advances in the surgical treatment of breast cancer over the last few years, and there's a lot of exciting areas of research and investigations to improve care. Here, we really focus hard on working together as a multidisciplinary team to formulate a bunch of treatment plans for patients. We're also here to help you sort through all these options and formulate a choice that's the best personal choice for you.

Streamlined care

A division surgeon discusses a plan of care with a patient.

Mayo Clinic understands that a diagnosis of breast cancer or melanoma is stressful for patients and families. In addition to emotional stress and uncertainty, it can be daunting to accommodate the travel, time and associated expense of obtaining care.

The Division of Breast and Melanoma Surgery Oncology is part of an integrated multidisciplinary group of cancer care specialties that provide streamlined collaboration for a comprehensive treatment plan that minimizes the time and expense of being away from home. Our surgical practice protocols are also designed to bring you detailed diagnosis and the best care as efficiently as possible. Our goal is to minimize the time between first seeking care and starting on your path to recovery.

Expedited brachytherapy treatment since 2012

For example, since 2012 Mayo Clinic has been using and refining a practice process for expedited brachytherapy treatment, for some women with low-risk, early-stage breast cancer.

  • Some patients may complete their entire treatment, including surgery and a full course of radiation, in fewer than 10 days. For certain specific profiles, the course of treatment may be even shorter, as little as five days.

Mayo Clinic's podcast on expedited breast cancer treatment options offers even more details.

BMSO surgeons work with internal medicine specialists dedicated to breast care and genetic counselors to help assess risk and tailor plans to mitigate risk that may involve screening, medications or surgery. Depending on the assessed level of risk, some women may want to consider risk-reducing mastectomy, or prophylactic mastectomy, often followed by reconstructive procedures.

Our multidisciplinary, high-volume practice features highly skilled breast surgeons and reconstructive plastic surgeons with special expertise in these advanced procedures. Based on a woman's individual circumstances and her preferences, our team designs the right plan for surgical risk reduction. For women interested in surgical risk reduction, our goal is to provide the greatest cancer risk reduction with the very best possible aesthetic outcomes for each woman.

Bilateral Prophylactic Mastectomy Surgery — Mayo Clinic

Tina J. Hieken, M.D., Breast/Melanoma Surgery, Mayo Clinic: There are several approaches a woman can choose from to decrease your risk of future breast cancer.

Surgery to remove both breasts is one approach to breast cancer risk reduction. Generally, surgical risk reduction is most appropriate for women at the highest risk for breast cancer, those with a known dangerous genetic mutation or women with a very strong family history of breast cancer. Surgery to remove both breasts is estimated to reduce the risk of subsequent breast cancer by 90 to 95 percent. This means that for a woman whose estimated lifetime risk of breast cancer is 40%, the chance that she will be diagnosed with breast cancer in her lifetime after bilateral risk reducing mastectomies is reduced to around 2 to 4%.

There are three main types of bilateral risk reducing operations that can be performed. Total mastectomy is generally done without reconstruction. This operation involves removal of the nipple areolar complex and the skin overlying the breast, so that after complete removal of the underlying breast tissue, the incision can be closed in a smooth flat line. This attention to closure is important so that a woman can wear a prosthesis comfortably inside, a specially design bra or swimsuit if she desires.

A second type of risk reducing mastectomy, a skin-sparing mastectomy. In this operation, the nipple areolar complex is removed, but an envelope of the overlying breast skin is preserved while all of the underlying breast tissue is removed. This permits breast reconstruction to be initiated at the same operation.

The third type of risk reducing mastectomy as nipple-sparing mastectomy. In this operation, the skin of the breast including the nipple areolar complex is preserved, the underlying breast tissue is completely removed and breast reconstruction is initiated at the same operation. In suitable women, the incision for a nipple-sparing mastectomy can be placed as a hidden scar on the under surface or side of the breast. This creates the most natural appearing reconstructed breast.

At Mayo Clinic, our multi-disciplinary and high-volume practice includes highly skilled breast oncologic surgeons and reconstructive plastic surgeons. Our team has special expertise in these advanced procedures. We work together as a team with women who want breast reconstruction following mastectomy. Based on a woman's individual circumstances and her preferences, our team designs an optimal plan for surgical risk reduction. Our goal is to provide maximal cancer risk reduction with the very best possible aesthetic outcomes for each woman.
