Hi scientistamafier,
Thank you for posting. It is understandable that you have questions about which arm to use for cannulation when you have had sentinel node biopsies on both sides.
Lymphoedema is swelling caused by a build-up of lymph fluid in the surface tissues of the body. This can happen as a result of damage to the lymphatic system following surgery and/or radiotherapy to the breast or axilla (armpit). Itās not clear why some people develop lymphoedema and others do not but the risk is greatest for those who have both surgery and radiotherapy to the axilla. People who have had a sentinel lymph node biopsy only, have a reduced risk of developing lymphoedema compared to people who have had a number of lymph nodes removed.
Thereās no strong evidence that having injections, taking blood, taking a blood pressure reading or having intravenous medicines in your āat riskā arm will cause lymphoedema. NICE guidance recommends that performing medical procedures on the treated side should depend on clinical need and the possibility of alternatives. As you have had the same surgery on each side you do not have an alternative option for cannulation, and it is reasonable to have your chemotherapy in either arm. However, as @naughty_boob says it is important to speak to your breast care nurse or treatment team about this if youāre worried.
There are ways in which to help reduce the risk of lymphoedema developing. Infection in your āat riskā arm can cause swelling and may damage the lymphatic system leading to lymphoedema. Tips on how to help reduce the risk of infection can be found in the link above.
Itās important to keep the skin clean and well moisturised, to reduce the risk of skin damage and infection.
