Prevention of breast cancer-related lymphoedema following axillary lymph node clearance

After surgery to remove lymph nodes in the armpit as part of breast cancer treatment, some people develop arm swelling called lymphoedema. This study tests whether a special arm massage technique called manual lymphatic drainage can help prevent this swelling when added to the standard care patients already receive. You may be eligible if: - You are having surgery to remove lymph nodes in your armpit for primary (first-time) breast cancer - This is your first breast cancer diagnosis and treatment You may NOT be eligible if: - Your breast cancer has come back (recurrent) - You have had previous surgery in your armpit - You have had radiation to your armpit before - You have had a previous condition causing arm swelling Talk to your doctor about whether this trial might be right for you.
