Thank you for your information. From my experience, Usually Oncologists in Top ranked cancer center are more experienced. I diagnosed cancer stage four about 8 months ago. My oncologist in a local hospital made a plan of chemotherapy only without being aware of what kind of cancer I have (there are multiple kinds, the related treatments are different). With her treatment plan, I probably am dying. Fortunately I did some research and visited other oncologists to figure out what kind of cancer I have and what treatment I shall have, so that I can survive until now. From this case, I learned that never reply on a doctor who does not care about patients or not good on her job. After visiting some doctors, I can easily tell if a doctor is a good one and if she/he cares about patients.
