How Common is Lymphoedema After Breast Cancer Treatment?

How Common is Lymphoedema After Breast Cancer Treatment?
The chance of developing lymphoedema after breast cancer treatment depends on several factors, including the type of surgery, whether lymph nodes were removed, and whether radiation therapy was used. Here’s a summary based on current clinical data:

• After sentinel lymph node biopsy (SLNB) only: Risk is relatively low — around 3–8%.
• After axillary lymph node dissection (ALND): Risk increases significantly — around 15–30%, sometimes reported up to 40%.
• After breast surgery plus radiation (especially to the axilla): Risk rises further, with estimates around 20–40%.

Other contributing factors include:

• Higher body mass index (BMI)
• Infections or injuries in the affected arm
• Extent of lymph node removal
• Chemotherapy (certain agents may slightly increase risk)
• Time since surgery (lymphoedema can occur months or even many years later)

This data highlights why ongoing awareness and prevention strategies are so important for anyone who has undergone breast cancer treatment.


Understanding the Risks of Lymphoedema After Breast Cancer Treatment
Lymphoedema is one of the potential long-term side effects following breast cancer treatment. While advances in surgery and radiation therapy have improved outcomes for many women, the risk of developing lymphoedema can remain, sometimes appearing months or even years later. Being informed about the causes, symptoms, and supportive options—such as specialist bras and compression garments—can help women take proactive steps to manage their wellbeing.
What is Lymphoedema? Lymphoedema is a swelling that occurs when lymphatic fluid builds up in the tissues. It most commonly affects the arm, breast, or chest wall after breast cancer surgery or radiation. The swelling happens because lymph nodes or vessels are removed or damaged, reducing the body’s ability to drain lymph fluid effectively.

Early Warning Signs of Lymphoedema Recognising the symptoms early can make a big difference in preventing progression. Look out for:

• Persistent swelling in the arm, chest, or breast
• A feeling of heaviness or tightness
• Reduced flexibility in the arm or shoulder
• Skin changes, such as thickening or tightness

If you notice these signs, it’s important to seek advice from a healthcare professional or a lymphoedema therapist.
Supportive Bras and Compression Solutions. The right post-surgical lingerie and compression garments can play a vital role in supporting lymphatic flow and keeping swelling under control. At Leila O’Toole, we recommend several specialist options: 

• Anita Lymph O Fit Bra – Designed with textured fabric that gently stimulates lymphatic drainage, supporting comfort and mobility.
