Precautions for tumor surgery 1. Be gentle when examining tumor, avoid squeezing and repeated examinations; 2. Avoid inappropriate local treatment of tumor, such as physiotherapy, herbal topical application, heat application, massage and pressure or local injection of drugs; 3. 5.For patients with other diseases, such as diabetes, cardiovascular disease, etc., they should be corrected in time before surgery and fully prepared for surgery; 6.Patients must be informed of their conditions and possible problems of surgery before surgery, especially disabling surgery; 7.Patients should be given appropriate psychological support treatment to relieve their psychological burden. Intraoperative precautions 1. Select the appropriate incision to fully reveal the field of view, and do not pull or squeeze the tumor excessively because the incision is too small; 2. If necessary, fast freezing can be performed. Postoperative treatment After resection of tumor, in addition to the post-surgical precautions, postoperative adjuvant treatment should be considered and should be implemented according to the original comprehensive treatment plan. Postoperative close follow-up and efficacy evaluation Unlike general postoperative review, postoperative follow-up of tumor patients is very necessary, which is responsible for monitoring the development of tumor and timely detection of tumor recurrence or metastasis. Therefore, cancer patients should be followed up regularly for life, generally once every 3 months in the first 2 years, once every 6 months in 2-5 years, and once a year after 5 years. The follow-up review should include physical examination and necessary laboratory and imaging examinations. Through regular follow-up observation, recurrent and metastatic lesions can be detected early and treated in time. In addition, long-term follow-up can evaluate the effect of surgical treatment and other treatment methods, which is very helpful to improve the treatment level.
