Removing the axillary lymph nodes increases your risk for developing lymphedema. The swelling, caused by an abnormal collection of too much fluid, is called lymphedema. It most often causes swelling of the arm, but it can also affect the breast, chest, and sometimes even the legs. Lymphedema is a chronic condition that is caused by a disruption or damage to the normal drainage pattern in the lymph nodes. If cancer cells are found in those lymph nodes, other cancer treatments will be considered. The additional nodes removed at the time of the breast cancer surgery will be examined by the pathologist in the following days to determine if others beyond the sentinel node contained cancer or not. Radiation to the underarm area and upper chest wall is also part of treatment.įor patients who are having a mastectomy surgery and have a positive sentinel node:įor these women, the standard of care remains the same, calling for the node removal and dissection of the axillary (or underarm) nodes.

This applies to postmenopausal patients who are over age 70 and whose cancer is estrogen receptor-positive.

When some evidence of cancer is found in the lymph system, recents standards are as follows:įor patients who are having a lumpectomy and the sentinel node is positive for cancer:Įffective in mid-2012, the standard of care was changed to no longer require women with early-stage breast cancers to have a full dissection and removal of the lymph nodes under the arm when the sentinel node is found to contain cancer. Following surgery, the pathologist will test the lymph nodes to determine whether the cancer has spread past the breast. Both procedures involve a separate incision for lumpectomy patients. A mastectomy or lumpectomy operation will most often include either a sentinel node biopsy or an axillary node dissection. Not always, especially when there is no evidence of any cancer in the lymph system. Once removed, they are dissected and examined by the pathologist, looking at all of the tissue and individual nodes very closely under a microscope.ĭo The Lymph Nodes Always Need To Be Removed? Axillary node dissection removes some of the the axillary lymph nodes, which are the lymph nodes located in the underarm. This procedure is a method for determining if the cancer has spread to more than one of your lymph nodes. Other tests, such as a culture, genetic tests, or immunological tests, may be done on the lymph node sample.A biopsy is nearly always taken from the sentinel node, and the breast surgeon typically removes the sentinel node as well for dissection. If a sentinel node is positive for cancer cells, more surgery may be needed to remove more lymph nodes. The lymph node can be taken out, cut into very thin slices, and looked at under a microscope at the time of surgery. Your doctor can see the dye or tracer with a special device. The map can show where the cancer is likely to spread and which lymph node is most likely to have cancer cells. The dye or tracer makes a map pattern of lymphatic fluid. The dye or tracer moves to the first lymph node (sentinel node) that drains close to the cancer site. Your doctor injects a blue dye or special tracer substance or both into the area around the original cancer site. For example, the sentinel node (SN) for breast cancer is normally one of the lymph nodes under the arm.

The sentinel lymph node is the first node in a group of nodes in the body where cancer cells may move to after they have left the original cancer site and started to spread. But if cancer is found in the sentinel lymph node at the time of surgery, more surgery may be needed to remove additional lymph nodes. A sentinel node biopsy may be done instead of a more extensive surgery called lymph node dissection. A sentinel node biopsy is used to see if a known cancer has spread from the original cancer site. A sentinel lymph node biopsy is a surgery that takes out lymph node tissue to look for cancer.
