Every year approximately 40,000 women are affected by breast cancer (20-25% of all female cancers). The treatments aimed to the removal of the tumoral mass lead to the development of lymphedema (important increase of the volume upper limb) that represents disabling element both from a physical and social point of view. The measurement of the limb with lymphedema and consequently the assessment of the degree of impairment are currently assigned in clinical routine to manual measurements, with a normal centimeter; this measure is subjective, not adequate to highlight all the morphological aspects of the limb, is not enough sensitive to identify changes induced by treatment, and also does not provide any information regarding the functional limitations associated with the increase in limb volume. Thus, the goal of the project, in collaboration with Istituto Nazionale dei Tumori of Milano, has been to provide clinical tools and methods of measurement of the limb affected by lymphedema and of its functional limitation during the execution of movements of everyday life.
