Not all adenocarcinomas are not recommended for surgery. Surgery is not recommended for adenocarcinoma either because the tumor stage is late, which cannot be removed by surgery or cannot achieve the therapeutic purpose, or the patient’s health is poor, which makes him/her unsuitable for surgery. 1. Late tumor stage: adenocarcinoma belongs to malignant tumors, and late malignant tumors often have extensive local invasion or distant metastasis, which can not be removed cleanly by surgery alone or surgery will not bring survival benefit to patients, but will cause damage to the body instead, and doctors may not recommend surgery. 2. When the patient’s health is poor: when the patient’s health is poor, such as heart failure, kidney failure, etc., and cannot tolerate the surgery, the surgery is not recommended, and if the surgery is forced, it may lead to serious complications and jeopardize the patient’s life. Besides, surgery may not be recommended for adenocarcinoma because it is not suitable for surgery at present and other treatments need to be done first before considering surgery. Not all adenocarcinomas are not recommended to be operated, some adenocarcinomas can be operated, for example, early lung adenocarcinomas are often treated with surgery. If adenocarcinoma is diagnosed, the treatment should be standardized according to the doctor’s prescription. Whether to adopt surgery or not needs to be evaluated and judged by specialists.
