A study out of McMaster University in Hamilton, suggests compression bandages work as well as daily massage for the treatment of breast-cancer related lymphedema. The condition is the result of the removal or damage of lymph nodes, which drain lymphatic fluid. The nodes are sometimes removed during breast cancer treatment, to minimize the risk of further spread. Up to 30-per cent of breast cancer patients can develop lymphedema, which can lead to discomfort, reduction of arm function and emotional upset.
