Breast Cancer Surgery

Nearly every breast cancer patient will have surgery as part of their breast cancer treatment. The goal of breast cancer surgery is to remove the tumor and to evaluate the axillary lymph nodes to determine if the cancer has spread.

From oncology nurses to surgeons, your MedStar Health healthcare team believes in treating the whole person, not just the disease, and will support you with the compassion you deserve and the excellence you expect every step of the way.

Partial Mastectomy/Lumpectomy

A partial mastectomy (often called a lumpectomy) is the most common form of breast cancer surgery. It is a surgical procedure to remove a tumor from within your breast, as well as some tissue surrounding the tumor—it does not remove the entire breast, which it is why it is considered a breast-conserving or -preserving surgery.

The size of the breast may be a bit smaller after a partial mastectomy. If needed, MedStar Health plastic surgeons will use oncoplastic techniques to restore symmetry and reduce the other side to match. 

Following surgery, most women will have radiation therapy to reduce the risk of cancer returning. Chemotherapy, if needed, is initiated before the radiation treatment. 

Axillary Lymph Node Dissection

The lymphatic system includes the nodes, tissues, and organs that produce and store infection-fighting white blood cells, as well as lymph, the fluid that circulates throughout this system. In a properly functioning lymphatic system, your lymph nodes filter out the lymph, eliminating bacteria and other waste products—including cancer cells.

If cancer cells begin to travel through the lymphatic system, they can end up in the lymph nodes; in cancers that begin in the breast, the closest lymph nodes are in the armpit area—the axillary lymph nodes. If your doctor determines that your breast cancer has spread to these nodes, you will need an axillary dissection.

Most often, your surgeon will remove the Level I and II lymph nodes during this procedure. Generally, 45 lymph nodes are in the axilla and, on average, 10-20 are removed during the operation.

Sentinel Lymph Node Biopsy

Sentinel lymph node biopsy is surgery to identify, remove, and microscopically examine the lymph nodes directly in the pathway of spreading cancer cells— to assess whether breast cancer has spread to lymph nodes under your arm, which are the most likely lymph nodes to contain cancer. Read more.
