Whether rectal cancer T2N0M0 recurs or not after surgery is different from individual’s situation, and is related to many factors, such as disease severity, completion of surgery, and postoperative life. 1. Disease severity: rectal cancer T2N0M0 refers to the primary tumor invading the intrinsic muscular layer, but without regional lymph node and distant organ metastasis, which belongs to stage I. Generally, the prognosis is better, and the recurrence rate after surgery is low. The 5-year survival rate of high-grade rectal cancer is higher than that of low-grade rectal cancer. 2. Surgical completion: radical resection of rectal cancer requires that the distance between the cancer and the cutting edge varies according to surgical methods, such as low anterior resection (Dixon’s surgery) requires that the distal part of the tumor should be at least 2cm away from the cutting edge, and if the scope of surgical resection fails to meet the requirement, it may lead to recurrence. 3. Postoperative life: Proper postoperative care and rehabilitation are effective in reducing the recurrence rate. Healthy lifestyle and psychological state can reduce complications and recurrence rate When rectal cancer occurs, one should consult the doctor in time, follow the doctor’s instruction to choose the appropriate treatment to avoid delaying the condition, and have regular rechecks after surgery to monitor the changes of the condition.
