Artificial Intelligence: the doctors Chinese patients can't beat up

For Zhao Changlin, an oncologist at a hospital in Guangzhou city, China, life is full of challenges. One of his patients, a woman with late-stage breast cancer, recently begged him to stop her chemotherapy, saying she could no longer bear the pain. Zhao knows only too well the torment the woman is going through – seeing people in pain is an unfortunate but everyday part of his job. He also knows that giving up the treatment could be fatal. "She is only 54 years old. If she continues the treatment, she may have another 20 years in front of her," Zhao said.
