Oncologists deliver bad news 20,000 times in their careers. We set out to give doctors more chances to deliver good news by considering all their treatment options. What we learned: Oncologists suffer from cancer too. When they break news of progression, they feel guilty and frustrated. Their treatment choice impacts patients and them. Collateral Cancer is a deeply human film exposing the underrecognized toll cancer has on doctors. In the moment difficult news is delivered, we reveal in a surprising twist how doctors carry the weight of cancer, and how vital their choices are to patients’ lives—and their own.
