Dr. Yan started treating my lung cancer more than a month ago. The first time I met Dr. Yan, he clearly analyzed and explained in details the certainties and uncertainties based on my CT-scan report, and afterward came up with a practical treatment plan. Subsequently Dr. Yan arranged every necessary test, and once he got sufficient clues from the test results, he determined targeted therapies, which have been in progress and very effective in the last two weeks, I believe. I really appreciate that Dr. Yan is caring, patient, and considerate. He is always available via SMS to answer my questions on body conditions and medications etc. With Dr. Yan as my oncologist, I am feeling optimistic in future fight against my cancer.
