Every time in outpatient clinic, there are always one or two such tumor patients, holding a test result and asking for surgical resection on the next day. If they don’t meet their requirements, they will find a lot of “acquaintances, friends” and other relationships to lobby for their favor, thinking that since they have been diagnosed with tumors, the fastest way to remove them is to “get rid of everything”. In fact, this is a kind of misunderstanding. Before the surgical treatment of most of the tumors, physicians not only need to obtain a confirmed diagnosis, but also need to evaluate the local infiltration of the tumor, the presence or absence of distant metastasis and the patient’s body’s tolerance of the surgery, so as to choose the most suitable treatment plan for the patient’s individuality: some patients can be operated immediately, some patients need to adjust their physical condition and improve their ability to tolerate the surgery before the surgery, and some of them need to undergo chemotherapy or radiotherapy before considering the surgery (e.g., chemo, radiotherapy, radiotherapy, radiotherapy). Others require chemotherapy or radiotherapy before surgery (so-called neoadjuvant therapy). In the past, the era of performing tumor surgery with a qualitative pathology test certificate and a lancet has passed. Some people may say that the time spent on checking and checking, while waiting for surgery, will probably lead to further development of the tumor. In reality, if the tumor develops rapidly during the limited time of waiting for the test results, this in itself indicates that an overly hasty surgery is not appropriate! It is feared that neoadjuvant therapy is more likely to be needed in this case. Even if surgery can be performed within a limited period of time after examination, there is still the problem of needing adjuvant treatment and regular follow-up after surgery. In my work, I have seen some colorectal cancer patients who, after being discharged from the hospital after surgery, threw away the doctor’s repeated advice of regular colonoscopy, and then, after 1-2 years of discomfort, tumors were found in other parts of the colon after re-examination.
