Lymph Node Surgery for Breast Cancer

Figuring out if (and where) breast cancer has spread is key to determining the most effective breast cancer treatments for each person. If you’ve recently been diagnosed with breast cancer, your doctor may recommend a low-risk, outpatient surgical procedure that looks for cancer cells in the lymph nodes beneath your arms. It’s called a sentinel lymph node biopsy.

The breast surgeons at The Janet Knowles Breast Cancer Center at MD Anderson Cancer Center at Cooper have deep expertise performing this lymph node surgery, with successful results.

Breast Cancer Lymph Node Surgery: What You Should Know

As part of your breast cancer treatment, your surgeon may remove some of the lymph nodes under your arm to learn if the cancer has spread. Here’s what you should know:

  • How and when the procedure is performed: Your doctor may recommend you have this biopsy at the same time, before, or after breast surgery, depending on the clinical circumstances. First, special dyes injected into the breast help locate which lymph nodes have cancer cells in them. If cancer cells are present, your doctor may need to remove all of the lymph nodes under your arm. This helps ensure they get rid of as much disease as possible.
  • Why we examine the lymph nodes: Your lymph nodes act as filters for your body’s lymphatic drainage system. They “catch” or filter out cancer cells that might be near the cancerous area of the breast. Your doctor may want to examine different nodes that are near your breasts, including those around your neck and collarbone and those found under your arm.
  • Points to note: If your doctor finds cancer in any of your lymph nodes, your risk of having cancer cells in other parts of your body increases. Your doctor will use this information to pinpoint which treatments are most likely to treat the cancer fully. Read more about our breast cancer surgery options.
