Liu stays on at Didi Kuaidi despite battling breast cancer

Liu Qing, one of the most powerful businesswomen in China, has been diagnosed with breast cancer.

The president of Didi Kuaidi, a mobile car-hailing platform, will continue to work at the company after having a tumor removed.

Liu, 37, was ranked last month as one of the most influential business people in the world under the age of 40 by Fortune magazine. Just days later, she revealed she was being treated for breast cancer in an internal e-mail to staff on Sept 30. "I had a small surgery several days ago and a tumor was removed," she said in the e-mail. "It turned out to be malignant, namely, breast cancer."
