LYMPHEDEMA OVERVIEW

Lymphedema is swelling caused by a build-up of fluid, usually in the arms in patients who have been treated for breast cancer. Lymphedema is one of the most troubling complications that can develop after breast cancer surgery. Many patients find that lymphedema worsens the physical and emotional strain of dealing with breast cancer.

The risk of developing lymphedema depends upon the type of surgery had, the time since surgery, and if radiation therapy was used. Generally, patients who undergo more extensive surgery, have many lymph nodes removed, or have radiation therapy to the axilla (arm pit) after surgery are more likely to develop lymphedema. Most patients who develop lymphedema do so within two years after their surgery, but it is important to note that it is a lifetime risk.
