Zhou Jun, Department of Gastroenterology and Oncology, Beijing Cancer Hospital: Many patients do not know what to do after they know they have tumor, so I will give you a summary here today in the simplest words: Step 1: clear diagnosis, for example: is it rectal cancer or not? This step of examination is usually to find a way to pathological biopsy. After it is clear that it is cancer, the second step is to clarify the stage, which is commonly known as: is my cancer early, middle or late? Is there metastasis or not? What is the location of metastasis? In this step, there are more tests, such as CT, MRI, blood sampling, B-ultrasound, etc., which are quite a lot, and the purpose is to make a comprehensive evaluation. The third step: according to the staging situation, combined with the family’s financial situation, decide the treatment, whether it is surgery, radiation therapy, or chemotherapy? Here to remind everyone, only the appropriate treatment for their own staging, is good treatment, like some places, obviously advanced, but also have to go to surgery, in most cases is to spend money for nothing. This is the proverbial: no culture, it’s terrible!
