As an oncologist, in clinical practice, we often encounter patients and family members who are at a loss, some of them even quite confident, and actually take a lot of detours. Misconception 1: Going to the clinic with empty hands or incomplete information. The first thing is that we have to prepare the information, put all the information of your previous visits to the hospital, if it is an inpatient, it is better to copy the medical records. This way the receiving doctor will have a detailed understanding of your current situation and can reduce many unnecessary tests. Misconception 2: Going to the best hospital, but not choosing the right doctor. Once a tumor patient is diagnosed, the first thing is to choose the right doctor. Always choose oncologist, if the first time patient visit medical oncologist, I emphasize medical oncologist, not general internist. This is because a medical oncologist can give you a plan for future treatment according to your condition and synthesize the existing treatment measures.
