Rectal cancer is one of the more common gastrointestinal diseases in life. Whether rectal cancer can be cured varies from person to person, and the most important thing is to choose the right method for treatment. First of all, if we want the disease to be cured better, we must choose the right method for treatment. For patients with rectal cancer, their own physical quality and the choice of treatment method are the keys to cure the disease. For patients with strong health and high immunity and resistance, if they can actively cooperate, the cure rate is still very high. However, if the patient is weak and has poor immunity and resistance, he or she will not be able to tolerate the intensity of disease treatment and will find it difficult to resist the invasion of cancer cells, so it is very important to maintain a healthy body. The principle of surgery is to remove all the tumors and kill the lesions to prevent recurrence of disease and metastasis. Therefore, the effect of radical surgery is very obvious for patients with small tumors and short course of disease. When patients choose surgery, we must do a good job of adjuvant treatment according to their own situation to help the disease recovery. After surgery, patients can choose radiotherapy, chemotherapy and Chinese herbal medicine for adjuvant treatment according to the recovery situation, which has a role of consolidation and promotion. These three treatment methods are more suitable for patients in the middle and late stages of the disease, because the disease has developed to a certain extent, the patient’s body has suffered different degrees of damage, and the physique has become very weak, surgery is no longer able to completely remove the tumor. 4.Radiotherapy and chemotherapy Radiotherapy and chemotherapy are adjuvant treatments which can effectively suppress cancer cells and promote the recovery of the disease. However, at the same time, radiotherapy and chemotherapy bring many side effects to the patients themselves and can also damage the normal cells in the body. Therefore, when choosing treatment, the dosage and duration of drugs should be chosen according to the body condition and the degree of the disease to prevent the side effects from bringing the disease to the trouble. 5.Chinese medicine treatment combined with radiotherapy Chinese medicine treatment is a very conservative treatment method, if it is combined with radiotherapy, it can effectively alleviate the toxic side effects of the disease and can see the effect of the treatment of the disease in the long run, which is a relatively good treatment method, but it takes time and is adhered to.
