It is true that cancer is a terrible disease, but it should not be faced and borne by one person or one family alone, but should be shared by the whole society, and requires all-round care from various professionals. Among them, psychological guidance is especially important. As a doctor, I would like to do more for patients and their families than just treating patients and saving lives. Here, I would like to help guide patients from a professional doctor’s point of view, purely from the aspect of medical treatment, on how to deal with colorectal cancer rationally after being told for the first time that they have cancer.
