Breast Cancer – Lymphedema

lymphedema and breast cancerLYMPHEDEMA AFTER BREAST CANCER

Breast cancer is one of the most common types affecting women today. About one in eight U.S. women will develop invasive breast cancer throughout her lifetime. During surgery to treat the tumor, lymph nodes are often removed, which can disrupt the flow of lymph and cause swelling. The lymph nodes may also be treated with radiation which can cause damage to the lymphatic system. This does not always occur after surgery or radiation, as sometimes it appears months or even years later. As a result, it’s common for breast cancer patients to develop lymphedema. Knowing your risk factor for this condition and ways to reduce your risk is essential.


There is no way to know for sure what your chances are of developing lymphedema. However, the good news is that researchers and healthcare professionals are continually developing new and better surgical treatments. Therefore, the cases of lymphedema today are significantly reduced. Most people do not get lymphedema since modern surgery removes fewer axillary lymph nodes than before. The more nodes removed, the greater the risk. Axillary node dissection removes more lymph nodes and gives you a higher chance of developing lymphedema. Sentinel lymph node biopsy removes only a few lymph nodes to check for cancer and gives you less than a 5% chance of developing lymphedema. When lymph nodes are removed, you will always be at higher risk for lymphedema.

Dr. Marisa Weiss, chief medical officer and founder of, says, “I can say from experience that the time right after diagnosis when you are considering options and planning treatment, is a blur. Feeling so anxious and overwhelmed makes it hard to listen, understand, and decide. So even if lymphedema gets mentioned during this time, you may not remember it. Or it may not come up because the focus is on getting you well. So if lymphedema does develop later on, it can feel like yet another insult to the body, one that many women weren’t fully prepared for. The good news is that women can learn how to manage it and lead everyday lives.“
