Breast Cancer Related Lymphoedema Women’s Clinic The following information aims to address the concerns you may have during your stay in hospital. We hope this information will help to give you more information about the condition. It is still unclear why some people develop lymphoedema after breast surgery. Similarly, it is not entirely clear what worsens the condition. This means that effective advice on care and management to prevent an aggravation is crucial. The greatest risk of infection is in the arm. Certain clinical procedures may increase the risk of secondary lymphoedema. As skin is the most effective defence against a possible infection, conscientious care of the skin is essential. The key procedures on the arm that are a cause for concern include: • Being given drugs intravenously • Having an intravenous (IV) drip inserted
• Having a tourniquet applied • Having your blood pressure measured • Having blood taken • Local excision • It is the patient’s choice in breast cancer treatment Intravenous therapy - inserting a drip into a vein and giving fluids or drugs - increases the potential risk of introducing an infection, but has not been clearly shown to increase the risk. The presence of lymphoedema indicates problems with fluid drainage from the limb. Alternative sites for injection of drugs should be used to avoid a possible fluid build up in the region. However, there are instances where the ability to induce fluids rapidly would be crucial as in the case of a life threatening blood loss. There are occasions (chemotherapy is a common example) when drugs may need to be given through a vein. In the long run, this method
may be harmful to the veins as it increases the chances of using up the veins in the other arm or feet. Where administration of lifesaving drugs is necessary, they should be given via the best possible route but if a need for repeated treatment arises, a more long-term intravenous access should be considered. This is usually a plastic catheter inserted through the skin into a deeper vein, typically in the neck. The catheter can be kept in place for weeks. Surgery for the compression of nerves at the wrist (carpal tunnel syndrome) is common in lymphoedema and a tourniquet is routinely used in this form of upper limb surgery. There is no evidence that using a tourniquet for up to 10 minutes bears any long-term effect though it may excite temporary growth in lymphoedema. Having blood drawn (venepuncture) from a vein carries little chances of introducing an infection in the limb. However, where there are alternative sites on the body, it is wiser to utilise those areas, even if it involves unusual locations such as the feet.
Measuring blood pressure involves a simple cuff on the arm which is inflated above the pressure in the arteries, and then rapidly deflated to record the blood pressure. There is no evidence that this makes any differemce at all to the risk of developing lymphoedema. However, changes in the volume of the arm may affect the accuracy of the recording and for this reason using the other limb would be more sensible. Frequently Asked Questions: 1. What makes me prone to developing lymphoedema? For unknown reasons, up to a third of patients get lymphoedema after surgery affecting their axillary lymph nodes. This can take a year or more to develop. There are many suggestions of ways to avoid triggering lymphoedema. However, there is a lack of evidence to support these suggestions. 2. If I have lymphoedema, what will make it worse? Once lymphodema develops, there are several methods of trying to avoid aggravating the condition. The chances of any medical procedure on the
