Cardia cancer can be treated surgically, but contraindications to surgery need to be ruled out before operation. 1. Cardia cancer is a solid malignant tumor with the pathology of adenocarcinoma or mucinous adenocarcinoma, and the effect of radiotherapy is poor, so surgical treatment is recognized as the first choice of treatment. 2. However, cardia cancer needs to be evaluated by relevant laboratory tests and examinations before surgery, so as to clarify the indications and exclude the contraindications for surgery. 3. In early stage cardia cancer, lymph node metastasis near the cardia is the main cause, the mass is relatively small, and the possibility of invading adjacent important organs such as liver, pancreas and aorta is small, so the cancer can be completely removed and radical surgery can be performed. 4. Surgery is not recommended for middle and late-stage cardia cancer or lymph node invasion to adjacent vital organs or distant metastasis, and palliative cancer resection cannot bring obvious benefits to patients. 5. Early stage pancreatic cancer patients basically do not have any discomfort. If patients have intermittent discomfort and light pain in the fossa, subxiphoid region or upper abdomen between meals, it is recommended to go to the hospital for examination in time. Early detection, early diagnosis and early treatment are the key to preventing and controlling pancreatic cancer. Early pancreatic cancer surgery has good effect, so it is recommended to go to the hospital for surgery as early as possible.
