A pair of Harvard-trained American oncologists, backed by Hong Kong billionaire Li Ka-shing, are attempting to harness technology to revamp cancer care. They're taking some of their earliest steps in China – cancer's ground zero. 

China has the world's largest number of cancer patients, yet specialised treatment is in such short supply that patients must often travel long distances to top hospitals, living in dilapidated housing for months for short oncologist visits.
