The Challenge

Compared to the U.S., medical care in China is drastically under-

resourced, with far worse cancer mortality outcomes.

Number of Oncologists

There are 26 oncologists per Million people in China. There are 60 oncologists per Million people in the U.S.

5-Year Cancer Survival Rate

 The 5-year cancer survival rate is only 40.5% in China, compared to 67% in the U.S.
