Cancer is one of the most deadly diseases in the United States, sometimes only making itself known when the window for the most effective treatments has passed. But it doesn't always have to be that way — and GRAIL’s team wants to ensure people are alerted to their diagnoses earlier than ever. Armed with cutting-edge machine learning technology, mountains of data, staggering computing power and a lot of grit, employees are equipped with the tools they need to transform the lives of cancer patients and their families, today and in the future. But no one person can do it alone, which is why collaboration, cross-functional teams and open communication aren’t just nice-to-haves. They’re deeply embedded in the DNA of every GRAIL employee.
