In Oncology, the player takes on the role of a newly hired oncologist at a radiation therapy clinic. Players meet with new patients, listening to their symptoms and offering responses based on notes and medical history. Patients are led to a CT scanner where the player is able to analyze cross sections of the body (using real life CT scans) and denote areas of cancerous tissue with a marker. After contouring treatable areas, players are given control of multiple radiotherapy beams and take on the task of positioning them in the best possible way in order to blast the cancer while avoiding healthy tissue.
Oncology was designed as a prototype for an even larger project, currently still in development, designed to harness the social aspect of Facebook and crowd source player's expertise in contouring cancerous tissue on CT scans. Oncology introduces the player to one of the leading ways doctors pinpoint the location of and treat tumors and gives them the same sets of tools these doctors use every day.
