The incidence of rectal cancer is second only to stomach cancer and esophageal cancer, it will directly affect the normalcy of human digestive system or not, so how long does rectal cancer reach advanced stage? What are the risks? From early to late stage of rectal cancer is related to the actual situation of each patient, adherence to treatment and a good state of mind are helpful to the healing of the disease, as well as the timely detection of rectal cancer. The 5-year survival rate of rectal cancer after surgery is significantly higher than that of solid malignant tumors such as stomach, lung, liver and esophagus. With the improvement of medical level, the 5-year survival rate of rectal cancer has increased from 50% to 70%, and the 5-year survival rate of colon cancer has increased from 70% to 80%. Since recurrence and metastasis still occur after radical surgery for rectal cancer, this is the key study of how long one can live after rectal cancer surgery. Recurrence after surgery is the residual cancer cells in the body playing a role, and the present hidden metastases may also be the result of failure to completely remove the lesions during surgery. Therefore, before dissection, intra-intestinal chemotherapy or preoperative enema administration for rectal cancer can stop the spread of cancer cells, kill and destroy cancer cells. Continuing chemotherapy treatment after surgery has the potential to improve the 5-year survival rate of rectal cancer after surgery. Each person has different disease development and different pathology, and the development rate of cancer is unpredictable. Generally, early stage is recommended to actively take surgery and combine with radiotherapy after surgery, together with Chinese medicine treatment
Reduce side effects. It depends on the patient’s physical condition. If the patient’s body allows it, surgery is recommended; if not, targeted interventional chemotherapy can be considered. Post-operative care 1.Patients will lose blood to different degrees during surgery, and blood supplementation by blood transfusion is far from good as self-generated blood, therefore, post-operative rectal cancer can appropriately increase some blood-supplementing diet, foods with high protein and iron, such as animal liver, lean meat, poultry and eggs, milk, carp, duck soup, cinnamon, silver fungus, turtle, etc., which are beneficial to patients’ recovery. 2.Because of bleeding during surgery and the hyper-secretory function of adrenal cortex, the amount of potassium excreted from the body increases, so that the blood potassium and intracellular potassium concentration decreases, so the patient should pay attention to increase the food containing more potassium after surgery, such as meat juice, vegetable soup, fruits with skin, etc. 3.Patients after surgery have weaker stomach and intestines, and generally have no appetite or anorexia for greasy food, so the diet should be light, try to do some small dishes and small porridge that meet the patient’s taste, and have a variety, and can have a small number of meals. You can drink some water 30 minutes after the meal. 4, in the diet should also be more vitamins, fresh fruit and squeezed into fresh juice to drink. 5, appropriate physical exercise to improve body resistance. 6, Cordyceps contains cordycepin that can phagocytose tumor cells, and also enhance the ability of red blood cells to adhere to tumor cells, which has good promotion effect on preventing tumor recurrence and metastasis. Patients can take it appropriately under the guidance of doctors.
