This multidisciplinary course aims at promoting an integrated approach to the management of breast cancer. The goal is to individualise the treatment based on the clinical presentation, prognostic (tumour) factors and patient-related issues. Breast cancer is a very common cancer and its’ treatment involves several different health care professionals. In the last decades, we have seen first a change in the attitude towards the treatment as data on the effectiveness of systemic treatment came out, followed by a new shift towards optimising the use of loco-regional treatments in view of the long-term follow-up data of the EBCTCG. The challenge to integrate all treatments for every single patient appeals for an optimal cooperation between all specialities involved in the care of breast cancer. Against this background, radiation oncologists are currently improving several technical aspects of delivery of radiotherapy, starting from optimal target volume definition. This urges for a refined collaboration with surgeons and pathologists. The course will be interactive through the integration of lectures, volume delineation workshops and patient management workshops and definitely multidisciplinary with a programme outlining the different treatments for breast cancer from evidence based medicine to ongoing research. The faculty includes a broad sample of the specialities involved in the management of breast cancer.
