Dr. Mei-Yoong Yap is THE BEST DOCTOR I've ever met. In February of 2017, by Kaiser Permanente, I was told that I had a massive tumor, called cholangiocarcinoma, and I had only 4 months to live. I don't like doctors that tell me when I will die. So I asked for a female oncologist doctor, that has options. They told me that Dr. Yap is the best. So, I asked for her. She is THE BEST DOCTOR! I didn't die in June! I am still very active, walking, driving, & living a wonderful life every day!!
