Rectal cancer is the third stage of advanced

Stage III rectal cancer is usually not advanced, but there are local invasion and metastasis, which is a great threat to health and life. Close follow-up is needed after treatment. Early detection and prevention are critical to improve survival rate. Stage III rectal cancer is usually not advanced, but there may be local invasion and regional lymph node metastasis, which is still a great threat to health and life of patients. Stage III rectal cancer is assessed based on the TNM staging system for the tumor. T represents the size and depth of the primary tumor, N represents regional lymph node metastasis, and M represents distant metastasis. In stage III rectal cancer, the tumor usually has invaded deep tissue in the rectal wall, but has not spread to distant organs. At this point, symptoms such as hematochezia, changes in bowel habits, abdominal pain, abdominal distension, etc. may occur. Treatment for stage III rectal cancer usually involves a combination of treatment methods, including surgery, radiotherapy, chemotherapy, targeted therapy, etc. Surgery is the main treatment, the goal is to completely remove the tumor and surrounding tissue. Radiotherapy and chemotherapy can be used as adjuvant treatment to reduce the risk of recurrence and metastasis. Follow-up and monitoring after treatment are important for patients with stage III rectal cancer. Regular follow-up, including physical examination and imaging, is performed to monitor recurrence and metastasis. It should be noted that the prognosis for stage III rectal cancer depends on a variety of factors, such as tumor differentiation, treatment effectiveness, and the overall health of the patient. Some patients can achieve better long-term survival and quality of life after aggressive treatment. For rectal cancer patients, especially high-risk groups such as familial polyposis and ulcerative colitis, regular colonoscopy and screening are key to early detection and treatment of rectal cancer. In addition, maintaining a healthy lifestyle, such as a balanced diet, moderate exercise, smoking cessation and alcohol restriction, can also help prevent the occurrence of rectal cancer. If diagnosed with stage III rectal cancer, patients should actively communicate with their doctors to understand the treatment options and prognosis, and follow the doctor's recommendations for treatment and follow-up. Patients and family members can also seek psychological support to cope with the psychological stress caused by the disease. Key message: Stage III rectal cancer is usually not advanced, but requires comprehensive treatment and close follow-up. Treatment effectiveness and prognosis depend on many factors, and early detection and prevention are essential to improve survival. Patients should actively cooperate with treatment, maintain a healthy lifestyle, and seek psychological support.
