This event is held every two years and had its first edition in 2011. Its characteristic is multidisciplinarity, the presentation of scientific works related to Oncology, as well as the participation of companies exhibiting innovative products and services for the health area.

In 2011, we reached an audience of 900 participants and in 2013, we reached a total of 1,200 people. The 3rd edition, held in 2015, was particularly remarkable, since, in addition to the participation of 1,000 congressmen, the event also hosted the 1st Radiology Workshop and the 1st Multidisciplinary Congress of Head and Neck Oncology.
