If you have an invasive breast cancer, your surgeoninfo-icon will need to check for cancer in one or several lymphinfo-icon nodes in the armpit on the side of the body where the cancer was found. Lymph nodes are organs that help the body filter out waste, bacteria and damaged cells.

This surgeryinfo-icon will usually be done at the same time as your breast surgery. What your doctors learn will help them find out the stageinfo-icon of the cancer and how best to treat it.

These are the most common types of lymph nodeinfo-icon surgery.

 

Sentinel Lymph Node Biopsy

To find out whether cancer is in the lymphinfo-icon nodes, a doctor removes a few lymph nodes from your underarm where the cancer is most likely to travel first. These are called the sentinel nodes.

Before surgeryinfo-icon, you will get an injectioninfo-icon of dye or dyes into your breast. At the time of surgery, the surgeoninfo-icon will look for the lymph nodes that have taken up the dye. The surgeon will send the sentinel nodes to a pathologistinfo-icon to test whether they have cancer. If they do not, no more nodes will be removed. If they do, your surgeon may remove more underarm lymph nodes, either at the time of your sentinel node biopsyinfo-icon or during another surgery.

Sentinel lymph node biopsyinfo-icon is usually not offered if you have:

Axillary Lymph Node Dissection

If cancer is found in your lymphinfo-icon nodes, you may need an axillary lymph node dissectioninfo-icon, or removal of most of the lymph nodes in the armpit. An axillary lymph node dissection will help your doctors stageinfo-icon the cancer and recommend treatment.

Axillary dissection is a more extensive surgeryinfo-icon than sentinel node biopsyinfo-icon. It has a higher risk for side effects such as shoulder stiffness and lymphedema. To address these side effects, your doctor may refer you to a physical therapistinfo-icon or a lymphedemainfo-icon specialistinfo-icon after you have an axillary lymph node dissection.

This type of surgery may not be recommended if you:

  • have no cancer in the lymph nodes
  • have cancer in 1 or 2 lymph nodes, and you plan on having a lumpectomyinfo-icon followed by radiation therapyinfo-icon

 

Questions To Ask Your Doctor

Here are some key questions to consider before surgeryinfo-icon:

  • How much, if any, cancer was found in the sentinel lymphinfo-icon nodes?
  • Will I have a sentinel lymph node biopsyinfo-icon or axillary dissection?
  • Why do you recommend one surgery over the other?
  • What are the risks for short- and long-term side effects?
  • Should I get neoadjuvant therapyinfo-icon, treatment before surgery?

Side Effects of Lymph Node Surgery

Lymph nodeinfo-icon surgeryinfo-icon is an important part of assessing and treating the breast cancer. But as with any surgery, lymph node surgery can have serious side effects. Talk with your doctors about these risks before you have surgery. They can help you understand the benefits of surgery over the risks of side effects.
